    Abstract: Policymakers often test expensive new programs on relatively small samples. Formally incorporating informative Bayesian priors into impact evaluation offers the promise to learn more from these experiments. A Colombian government program which aimed to increase exporting was trialed experimentally on 200 firms with this goal in mind. Priors were elicited from academics, policymakers, and firms. Contrary to these priors, frequentist estimation can not reject 0 effects in 2019, and finds some negative impacts in 2020. For binary outcomes like whether firms export, frequentist estimates are relatively precise, and Bayesian credible posterior intervals update to overlap almost completely with standard confidence intervals. For outcomes like increasing export variety, where the priors align with the data, the value of these priors is seen in posterior intervals that are considerably narrower than frequentist confidence intervals. Finally, for noisy outcomes like export value, posterior intervals show almost no updating from the priors, highlighting how uninformative the data are about such outcomes

    Abstract: Should governments in developing countries directly support firms with policies such as grants, subsidized loans, and training and consulting programs, or should they instead just aim to enact sensible regulatory and macroeconomic policies and not attempt to engage in industrial policy While industrial policy has gained renewed attention in developed economies, it faces considerable skepticism in developing countries scarred by previous experiences and facing limited fiscal space. This paper discusses the rationale for government involvement, and then lessons from a recent research agenda in development economics on how to target these programs, on whether they induce firms to undertake additional activities, on avoiding political capture, and on how these interact with competition. This work shows that these policies can deliver some of their promised benefits, but that there is still much to learn and the need for systematic and serious attempts at prospective impact evaluation as new policies are launched

    Abstract: Migration changes how families form and dissolve, and how one should conceptualize the family. This has implications for thinking about how the migration decision is modelled when individuals are unable to picture the counterfactual families they may have. Differences in marital status can induce two otherwise identical individuals to make different migration decisions. It also has implications for attempts to causally estimate impacts of migration, when the family composition changes with the migration decision itself. This paper shows empirically that changing marital status after migration is widespread, and that the traditional model of a fixed family sending off a migrant who remains part of that same family only describes a minority of migrants moving from developing countries to the U.S. The authors draw out lessons from thinking about counterfactual families for empirical research and for migration policy

    Abstract: The claim that social protection is a luxury good-with a national income elasticity exceeding unity-has been influential. The paper tests the "luxury good hypothesis" using newly-assembled data on social protection spending across countries since 1995, treating the pandemic period separately, as it entailed a large expansion in social protection efforts. While the mean income share devoted to social protection rises with income, this is attributable to multiple confounders, including relative prices, weak governance in low-income countries and access to information-communication technologies. Controlling for these, social protection is not a luxury good. This was also true during the pandemic

    Abstract: The limited market size of many small emerging economies is a key constraint to the growth of innovative small and medium enterprises. Exporting offers a potential solution, but firms may struggle to locate and appeal to foreign buyers. A six-country randomized experiment was conducted with 225 firms in the Western Balkans to test the effectiveness of 30 hours of live group-based training and 5 hours of one-on-one remote consulting in overcoming these constraints. Treated firms used techniques such as search engine optimization and improved Facebook content to increase their digital presence and better reach foreign customers. A year later, positive and significant impacts are found on the number of customers, and a significant intensive margin increase in export sales. Qualitative interviews suggest this improvement came from a combination of sector-specific advice on market expansion, and through an encouragement effect which gave entrepreneurs the confidence to try new sales strategies

    Keywords: Difference-In-Differences ; Economic Growth ; Experimental Methods ; Instrumental Variables ; Migration Experiments ; Natural Experiment ; Regression Discontinuity ; Social Protection and Labor
    Abstract: Many research and policy questions surrounding migration are causal questions. What causes people to migrate? What are the consequences of migration for the migrants, their families, and their communities? Answering these questions requires dealing with the self-selection inherent in migration choices. Field and natural experiments offer methodological approaches that enable answering these causal questions. This paper discusses the key conceptual and logistical issues that face applied researchers when applying these methods to the study of migration, as well as providing guidance for practitioners and policymakers in assessing the credibility of causal claims. For randomized experiments, this includes providing a framework for thinking through what can be randomized; discussing key measurement and design issues that arise from issues such as migration being a rare event, and in measuring welfare changes when people change locations; as well as discussing ethical issues that can arise. The paper then outlines what makes for a good natural experiment in the context of migration, and discusses the implications of recent econometric work for the use of difference-indifferences, instrumental variables (and especially shift-share instruments), and regression discontinuity methods in migration research. A key lesson from this recent work is that it is not meaningful to talk about ?the? impact of migration, but rather impacts are likely to be heterogeneous, affecting both the validity and interpretation of causal estimates

    Fears and Tears : Should More People be Moving within and from Developing Countries, and what Stops this Movement? (2022)

    Abstract: Only one in seven of the world's population has ever migrated, despite the enormous gains in income possible through international and internal movement. This paper examines the evidence for different explanations given in the economics literature for this lack of movement and their implications for policy. Incorrect information about the gains to migrating, liquidity constraints that prevent poor people paying the costs of moving, and high costs of movement arising from both physical transportation costs and policy barriers all inhibit movement and offer scope for policy efforts to inform, provide credit, and lower moving costs. However, the economics literature has paid less attention to the fears people have when faced with the uncertainty of moving to a new place, and to the reasons behind the tears they shed when moving. While these tears reveal the attachment people have to particular places, this attachment is not fixed, but itself changes with migration experiences. Psychological factors such as a bias toward the status quo and the inability to picture what one is giving up by not migrating can result in people not moving, even when they would benefit from movement and are not constrained by finances or policy barriers from doing so. This suggests new avenues for policy interventions that can help individuals better visualize the opportunity costs of not moving, alleviate their uncertainties, and help shift their default behavior from not migrating

    Abstract: The COVID-19 pandemic has resulted in border closures in many countries and a sharp reduction in overall international mobility. However, this disruption of legal pathways to migration has raised concerns that potential migrants may turn to irregular migration routes as a substitute. This paper examines how the pandemic has changed intentions to migrate from The Gambia, the country with the highest pre-pandemic per-capita irregular migration rates in Africa. A large-scale panel survey conducted in 2019 and 2020 is used to compare changes in intentions to migrate to Europe and to neighboring Senegal. The data show that the pandemic has reduced the intention to migrate to both destinations, with approximately one-third of young males expressing less intention to migrate. The largest reductions in migration intentions are for individuals who were unsure of their intent pre-pandemic, and for poorer individuals who are no longer able to afford the costs of migrating at a time when these costs have increased and their remittance income has fallen. This paper also introduces the methodology of priming experiments to the study of migration intentions, by randomly varying the salience of the COVID-19 pandemic before eliciting intentions to migrate. There is no impact of this added salience, which appears to be because knowledge of the virus, while imperfect, was already enough to inform migration decisions. Nevertheless, despite these decreases in intentions, the overall desire to migrate the backway to Europe remains high, highlighting the need for legal migration pathways to support migrants and divert them from the risks of backway migration

    Abstract: The paper simulates a double-sided competitive market in temporary work permits between the U.S. and Mexico. Eligible working-age Americans would have the option of renting out their implicit work permits while Mexican workers have remunerative new opportunities. With plausible allowances for migration costs, the market can support a self-financed and self-targeted basic income for Americans and lower their poverty rate. With sufficiently high tax rates on work permits, the scheme can be managed to avoid a large increase in the count of total migrants compared to now. The likely change in the skill composition of migrants would raise U.S. GDP

    Abstract: The predictions of different classic migration theories are tested by using incentivized laboratory experiments to investigate how potential migrants decide between working in different destinations. First, the authors test theories of income maximization, migrant skill-selection, and multi-destination choice as they vary migration costs, liquidity constraints, risk, social benefits, and incomplete information. The standard income maximization model of migration with selection on observed and unobserved skills leads to a much higher migration rate and more negative skill-selection than is obtained when migration decisions take place under more realistic assumptions. Second, these lab experiments are used to investigate whether the independence of irrelevant alternatives assumption holds. The results show that it holds for most people when decisions just involve wages, costs, and liquidity constraints. However, once the risk of unemployment and incomplete information is added, independence of irrelevant alternatives no longer holds for about 20 percent of the sample

    What Prevents More Small Firms from Using Professional Business Services? : An Information and Quality-Rating Experiment in Nigeria (2021)

    Abstract: Why do more small firms in developing countries not use the market for professional business services like accounting, marketing, and human resource specialists? Two key reasons may be that firms lack information about the availability of these services, and that they struggle to distinguish the quality of good versus bad providers. A brand recognition exercise finds that most small firms are unaware of most providers in this market, and a survey of service providers reveals that they largely rely on word-of-mouth and informal reputation mechanisms for acquiring customers. This study set up a business services marketplace that contains information about the different providers present in the market and used mystery shopper visits to develop a quality ratings system. A randomized experiment with more than 1,000 firms provided access to this marketplace to the treatment group and randomized whether firms received just information or also quality ratings. The provision of quality ratings information shifts small firms' preferences over which provider they would like to use, increasing the average quality rating of their preferred providers by 0.2 to 0.4 ratings points out of 5. However, neither the provision of information nor these quality ratings had any significant impact on the likelihood that small firms go on to hire a business service provider over the subsequent six months. The results suggest that alleviating information frictions alone is insufficient to increase usage of professional business services

    Abstract: A randomized experiment among poor entrepreneurs tested the impact of exogenously inducing higher financial aspirations. In theory, raising aspirations could have positive effects by inducing higher effort, but could also reduce effort if unmet aspirations lead to frustration. Treatment resulted in more ambitious savings goals, but nearly all individuals fell far short of reaching these goals. Two years later, treated individuals had not saved more, and actually had lower borrowing and business investments. Treatment also reduced belief in the amount of control over one's life. Setting aspirations too high can lead to frustration, leading individuals to reduce their economic investments

    Abstract: The paper provides new measures of global poverty that take seriously the idea of relative-income comparisons but also acknowledge a deep identification problem when the latent norms defining poverty vary systematically across countries. Welfare-consistent measures are shown to be bounded below by a fixed absolute line and above by weakly-relative lines derived from a theoretical model of relative-income comparisons calibrated to data on national poverty lines. Both bounds indicate falling global poverty incidence, but more slowly for the upper bound. Either way, the developing world has a higher poverty incidence but is making more progress against poverty than the developed world

    Abstract: Antipoverty policies in developing countries often assume that targeting poor households will be reasonably effective in reaching poor individuals. This paper questions this assumption, using nutritional status as a proxy for individual poverty. The comprehensive assessment for Sub-Saharan Africa reveals that undernourished women and children are spread widely across the distribution of household wealth and consumption. Roughly three-quarters of underweight women and undernourished children are not found in the poorest 20 percent of households, and around half are not found in the poorest 40 percent. The mean joint probability of being an underweight woman and living in the poorest wealth quintile is only 0.03. Countries with higher overall rates of undernutrition tend to have a higher share of undernourished individuals in nonpoor households. The results are consistent with evidence of substantial intrahousehold inequality

    Abstract: A common concern with efforts to directly help some small businesses to grow is that their growth comes at the expense of their unassisted competitors. This study tests this possibility using a two-stage randomized experiment in Kenya. The experiment randomizes business training at the market level, and then within markets to selected businesses. Three years after training, the treated businesses are selling more, earn higher profits, and their owners have higher well-being. There is no evidence of negative spillovers on the competing businesses, and the markets as a whole appear to have grown in terms of number of customers and sales volumes. This market growth appears to come from enhanced customer service and new product introduction, generating more customers and more sales from existing customers. As a result, business growth in underdeveloped markets is possible without taking sales away from nontreated businesses

    Abstract: It is theoretically ambiguous whether growth of cities matters more to the rural poor than growth of towns. This paper empirically examines whether growth of India's secondary towns or big cities mattered more to recent rural poverty reduction, noting that data deficiencies have made this a difficult question to answer previously. Satellite observations of night lights are used to measure urban growth on the extensive and intensive margins in the context of a spatial Durbin fixed-effects model of poverty measures for rural India, calibrated to a panel of 59 regions observed four times over 1993-2012. The expansion of lit area had greater effect on the rural poverty measures than did intensive margin growth in the brightness of light from urban areas. For India's current stage of development, growth of secondary towns may do more to reduce rural poverty than big city growth, although the theoretical model suggests that cities may eventually take over from towns as the drivers of rural poverty reduction

    Abstract: Jobs are the number one policy concern of policy makers in many countries. The global financial crisis, rising demographic pressures, high unemployment rates, and concerns over automation all make it seem imperative that policy makers employ increasingly more active labor market policies. This paper critically examines recent evaluations of labor market policies that have provided vocational training, wage subsidies, job search assistance, and assistance moving to argue that many active labor market policies are much less effective than policymakers typically assume. Many of these evaluations find no significant impacts on either employment or earnings. One reason is that urban labor markets appear to work reasonably well in many cases, with fewer market failures than is often thought. As a result, there is less of a role for many traditional active labor market policies than is common practice. The review then discusses examples of job creation policies that do seem to offer promise, and concludes with lessons for impact evaluation and policy is this area

    Abstract: Financial education programs are increasingly offered by governments, nonprofits, and financial institutions. However, voluntary participation rates in such programs are often very low, posing a severe challenge for randomized experiments attempting to measure their impact. This study uses a large experiment on more than 100,000 credit card clients in Mexico. The study shows how the richness of financial data allows combining nonexperimental methods with the experiment to yield credible measures of impact, even with take-up rates below 1 percent. The findings show that a financial education workshop and personalized coaching result in a higher likelihood of paying credit cards on time, and of making more than the minimum payment, but do not reduce spending, resulting in higher profitability for the bank

However, most informal firms have not gone on to become formal, especially when tax registration is involved. A randomized experiment based around the introduction of the entreprenant legal status in Benin is used to provide evidence from an African context on the willingness of informal firms to register after introducing a simple, free registration process, and to test the effectiveness of supplementary efforts to enhance the presumed benefits of formalization by facilitating its links to government training programs, support to open bank accounts, and tax mediation services. Few firms register when just given information about the new regime, but 9.6 percentage points more register when they were visited in person and the benefits were explained. The full package of supplementary efforts boosts the impact on the formalization rate to 16.3 percentage points, demonstrating that enhancing the benefits of formalization does induce more firms to formalize. Firms that are larger, and that look more like formal firms to begin with, are more likely to formalize, providing guidance for better targeting of such policies. However, formalization appears to offer limited benefits to the firms, and the costs of personalized assistance are high, suggesting that such enhanced formalization efforts are unlikely to pass cost-benefit tests

    Parallel Title: Erscheint auch als de Mel, Suresh Labor Drops: Experimental Evidence on the Return to Additional Labor in Microenterprises
    Abstract: The majority of enterprises in many developing countries have no paid workers. This paper reports on a field experiment conducted in Sri Lanka that provided wage subsidies to randomly chosen microenterprises to test whether hiring additional labor would benefit such firms. In the presence of labor market frictions, a short-term subsidy could have a lasting impact on firm employment. Using 12 rounds of surveys to track dynamics four years after the end of the subsidy, the study finds that firms increased employment during the subsidy period, but there was no lasting impact on employment, profitability, or sales. Two supplementary interventions and treatment heterogeneity suggest the lack of impact is not due to complementarities with capital or management skills, and detailed survey data help rule out a number of theoretical mechanisms that could result in sub-optimally low employment. The study concludes that the urban labor market facing microenterprises does not have large frictions that would prevent own-account workers from becoming employers

    Abstract: Longstanding development issues are revisited in the light of a newly-constructed data set of poverty measures for India spanning 60 years, including 20 years since reforms began in earnest in 1991. The study finds a downward trend in poverty measures since 1970, with an acceleration post-1991, despite rising inequality. Faster poverty decline came with higher growth and a more pro-poor pattern of growth. Post-1991 data suggest stronger inter-sectoral linkages: urban consumption growth brought gains to the rural as well as the urban poor, and the primary-secondary-tertiary composition of growth has ceased to matter, as all three sectors contributed to poverty reduction

    Parallel Title: Erscheint auch als Brown, Caitlin A Poor Means Test? Econometric Targeting in Africa
    Abstract: Proxy-means testing is a popular method of poverty targeting with imperfect information. In a now widely-used version, a regression for log consumption calibrates a proxy-means test score based on chosen covariates, which is then implemented for targeting out-of-sample. In this paper, the performance of various proxy-means testing methods is assessed using data for nine African countries. Standard proxy-means testing helps filter out the nonpoor, but excludes many poor people, thus diminishing the impact on poverty. Some methodological changes perform better, with a poverty-quantile method dominating in most cases. Even so, either a basic-income scheme or transfers using a simple demographic scorecard are found to do as well, or almost as well, in reducing poverty. However, even with a budget sufficient to eliminate poverty with full information, none of these targeting methods brings the poverty rate below about three-quarters of its initial value. The prevailing methods are particularly deficient in reaching the poorest

    Abstract: Management has a large effect on the productivity of large firms. But does management matter in micro and small firms, where the majority of the labor force in developing countries works? This study developed 26 questions that measure business practices in marketing, stock-keeping, record-keeping, and financial planning. These questions have been administered in surveys in Bangladesh, Chile, Ghana, Kenya, Mexico, Nigeria, and Sri Lanka. This paper shows that variation in business practices explains as much of the variation in outcomes-sales, profits, and labor productivity and total factor productivity-in microenterprises as in larger enterprises. Panel data from three countries indicate that better business practices predict higher survival rates and faster sales growth. The effect of business practices is robust to including many measures of the owner's human capital. The analysis finds that owners with higher human capital, children of entrepreneurs, and firms with employees employ better business practices. Competition has less robust effects

    Abstract: Almost all firms in developing countries have fewer than 10 workers, with the modal firm consisting of just the owner. Are there potential high-growth entrepreneurs with the ability to grow their firms beyond this size? And, if so, can public policy help alleviate the constraints that prevent these entrepreneurs from doing so? A large-scale national business plan competition in Nigeria is used to help provide evidence on these two questions. The competition was launched with much fanfare, and attracted almost 24,000 entrants. Random assignment was used to select some of the winners from a pool of semi-finalists, with US

    Parallel Title: Erscheint auch als Benhassine, Najy Finding a Path to Formalization in Benin: Early Results after the Introduction of the Entreprenant Legal Status
    Abstract: In April 2014, the Government of Benin launched the entreprenant status, a simplified and free legal regime offered to small informal businesses to enter the formal economy. This paper presents the short-term results of a randomized impact evaluation testing three different versions of the entreprenant status on business registration decisions, each version including incremental incentives to registration: (i) information on the new legal status and its benefits, (ii) business training, counseling services, and support to open a bank account, (iii) tax mediation services. The study included 3,600 informal businesses operating with a fixed location in Cotonou, Benin, which were randomly allocated between three treatment groups and one control group. One year after the program launch, all versions of the program had significant impact on formalization rates. The impact was 9.1 percentage points in the first treatment group; 13 percentage points in the second group; and 15.8 percentage points in the last group. The program had a higher impact on male business owners, with more education, operating outside Dantokpa Market, in sectors other than trade, and that before being offered the incentives to formalization had characteristics similar to businesses that were already formal. Data from a second follow-up survey, which is expected to take place in March 2016, will explore the impacts on other outcomes, like business performances or access to banking

    Abstract: This study examines the long-term impacts of international migration by comparing immigrants who had successful ballot entries in a migration lottery program, and first moved almost a decade ago, with people who had unsuccessful entries into those same ballots. The long-term gain in income is found to be similar in magnitude to the gain in the first year, despite migrants upgrading their education and changing their locations and occupations. This results in large, sustained benefits to the migrants' immediate family, who have substantially higher consumption, durable asset ownership, savings, and dietary diversity. In contrast, the study finds no measureable impact on extended family

    Abstract: This paper evaluates a youth internship program in the Republic of Yemen that provided firms with a 50 percent subsidy to hire recent graduates of universities and vocational schools. The first round of the program took place in 2014 and required both firms and youth to apply for the program. The paper examines the demand for such a program, and finds that in the context of an economy facing substantial political and economic uncertainty, it appears there is an oversupply of graduates in science, technology, engineering, and mathematics, and a relative undersupply of graduates in marketing and business. Conditional on the types of graduates firms were looking to hire as interns, applicants were then randomly chosen for the program. Receiving an internship resulted in an almost doubling of work experience in 2014, and a 73 percent increase in income during this period compared with the control group. A short-term follow-up survey conducted just as civil conflict was breaking out shows that internship recipients had better employment outcomes than the control group in the first five months after the program ended

    Abstract: Matching grants are one of the most common types of private sector development programs used in developing countries. But government subsidies to private firms can be controversial. A key question is that of additionality: do these programs get firms to undertake innovative activities that they would not otherwise do, or merely subsidize activities that would take place anyway? Randomized controlled trials can provide the counterfactual needed to answer this question, but efforts to experiment with matching grant programs have often failed. This paper uses a randomized controlled trial of a matching grant program for firms in the Republic of Yemen to demonstrate the feasibility of conducting experiments with well-designed programs, and to measure the additionality impact. In the first year, the matching grant is found to have led to more product innovation, firms upgrading their accounting systems, marketing more, making more capital investments, and being more likely to report their sales grew

    Abstract: Despite regulatory efforts designed to make it easier for firms to formalize, informality remains extremely high among firms in Sub-Saharan Africa. In most of the region, business registration in a national registry is separate from tax registration. This paper provides initial results from an experiment in Malawi that randomly allocated firms into a control group and three treatment groups: a) a group offered assistance for costless business registration; b) a group offered assistance with costless business registration and (separate) tax registration; and c) a group offered assistance for costless business registration along with an information session at a bank that ended with the offer of business bank accounts. The study finds that all three treatments had extremely large impacts on business registration, with 75 percent of those offered assistance receiving a business registration certificate. The findings offer a cost-effective way of getting firms to formalize in this dimension. However, in common with other studies, information and assistance has a limited impact on tax registration. The paper measures the short-term impacts of formalization on financial access and usage. Business registration alone has no impact for either men or women on bank account usage, savings, or credit. However, the combination of formalization assistance and the bank information session results in significant impacts on having a business bank account, financial practices, savings, and use of complementary financial products

A detailed follow-up survey of a large sample with low attrition enables precise estimation of treatment impacts and their heterogeneity. The average impact of training on employment is positive, but close to zero and statistically insignificant, which is much lower than either program officials or applicants expected. Over the first year after training, the paper finds that training had statistically significant effects on the quality of employment and that the positive impacts are stronger when training is offered by private providers. However, longer-term administrative data show that after three years these effects have also dissipated

    Abstract: This paper reviews the empirical evidence on the existence of poverty traps, understood as self-reinforcing mechanisms through which poor individuals or countries remain poor. Poverty traps have captured the interest of many development policy makers, because poverty traps provide a theoretically coherent explanation for persistent poverty. They also suggest that temporary policy interventions may have long-term effects on poverty. However, a review of the reduced-form empirical evidence suggests that truly stagnant incomes of the sort predicted by standard models of poverty traps are in fact quite rare. Moreover, the empirical evidence regarding several canonical mechanisms underlying models of poverty traps is mixed

    Abstract: Although measured remittances by migrant workers have soared in recent years, macroeconomic studies have difficulty detecting their effect on economic growth. This paper reviews existing explanations for this puzzle and proposes three new ones. First, it offers evidence that a large majority of the recent rise in measured remittances may be illusory-arising from changes in measurement, not changes in real financial flows. Second, it shows that even if these increases were correctly measured, cross-country regressions would have too little power to detect their effects on growth. Third, it points out that the greatest driver of rising remittances is rising migration, which has an opportunity cost to economic product at the origin. Net of that cost, there is little reason to expect large growth effects of remittances in the origin economy. Migration and remittances clearly have first-order effects on poverty at the origin, on the welfare of migrants and their families, and on global gross domestic product; but detecting their effects on growth of the origin economy is likely to remain elusive

    Parallel Title: De Arcangelis, Giuseppe Directing Remittances to Education with Soft and Hard Commitments
    Abstract: This paper tests how migrants' willingness to remit changes when given the ability to direct remittances to educational purposes using different forms of commitment. Variants of a dictator game in a lab-in-the-field experiment with Filipino migrants in Rome are used to examine remitting behavior under varying degrees of commitment. These range from the soft commitment of simply labeling remittances as being for education, to the hard commitment of having funds directly paid to a school and the student's educational performance monitored. The analysis finds that the introduction of simple labeling for education raises remittances by more than 15 percent. Adding the ability to directly send this funding to the school adds only a further 2.2 percent. The information asymmetry between migrants and their most closely connected household is randomly varied, but no significant change is found in the remittance response to these forms of commitment as information varies. Behavior in these games is shown to be predictive of take-up of a new financial product called EduPay, designed to allow migrants to pay remittances directly to schools in the Philippines. This take-up seems largely driven by a response to the ability to label remittances for education, rather than to the hard commitment feature of directly paying schools

    Abstract: Unemployment rates for tertiary-educated youth in Jordan are high, as is the duration of unemployment. Two randomized experiments in Jordan were used to test different theories that may explain this phenomenon. The first experiment tested the role of search and matching frictions by providing firms and job candidates with an intensive screening and matching service based on educational backgrounds and psychometric assessments. Although more than 1,000 matches were made, youth rejected the opportunity to even have an interview in 28 percent of cases, and when a job offer was received, they rejected this offer or quickly quit the job 83 percent of the time. A second experiment built on the first by examining the willingness of educated, unemployed youth to apply for jobs of varying levels of prestige. Youth applied to only a small proportion of the job openings they were told about, with application rates higher for higher prestige jobs than lower prestige jobs. Youth failed to show up for the majority of interviews scheduled for low prestige jobs. The results suggest that reservation prestige is an important factor underlying the unemployment of educated Jordanian youth

    Abstract: Accurate measurement of stock levels, turnover, and profitability in microenterprises in developing countries is difficult because the majority of these firms do not keep detailed records. This paper tests the use of radio frequency identification tags as a means of objectively measuring stock levels and stock flow in small retail firms in Sri Lanka. In principle, the tags offer the potential to track stock movements accurately. The paper compares the stock counts obtained from RFID reads to physical stock counts and to survey responses. There are three main findings. First, current RFID-technology is more difficult to use, and more time-consuming to employ, than had been envisaged. Second, the technology works reasonably well for paper products, but very poorly for most products sold by microenterprises: on average only about one-quarter of the products tagged could be read and there was considerable day-to-day variation in read-efficiency. Third, a comparison of survey responses and physical stock-takes shows much higher accuracy for survey measures. As a result, the study concludes that this technology is currently unsuitable for improving stock measurement in microenterprises, except perhaps for a few products

    Parallel Title: Gibson, John Development through Seasonal Worker Programs
    Abstract: Seasonal worker programs are increasingly seen as offering the potential to be part of international development policy. New Zealand's Recognised Seasonal Employer program is one of the first and most prominent of programs designed with this perspective. This paper provides a detailed examination of this policy through the first six seasons. This includes the important role of policy facilitation measures taken by governments and aid agencies. The evolution of the program in terms of worker numbers is discussed, along with new data on the (high) degree of circularity in worker movements, and new data on (very low) worker overstay rates. There appears to have been little displacement of New Zealand workers, and new data show Recognised Seasonal Employer workers to be more productive than local labor and that workers appear to gain productivity as they return for subsequent seasons. The program has also benefitted the migrants participating in the program, with increases in per capita incomes, expenditure, savings, and subjective well-being. Taken together, this evidence suggests that the program is largely living up to its promise of a "triple win" for migrants, their sending countries in the Pacific, and New Zealand

    Parallel Title: Groh, Matthew Macroinsurance for Microenterprises
    Abstract: Firms in many developing countries cite macroeconomic instability and political uncertainty as major constraints to their growth. Economic theory suggests uncertainty can cause firms to delay investments until uncertainty is resolved. A randomized experiment was conducted in post-revolution Egypt to measure the impact of insuring microenterprises against macroeconomic and political uncertainty. Demand for macroeconomic shock insurance was high; 36.7 percent of microentrepreneurs in the treatment group purchased insurance. However, purchasing insurance does not change the likelihood that a business takes a new loan, the size of the loan, or how the loan is invested. This lack of effect is attributed to microenterprises largely investing in inventories and raw materials rather than irreversible investments like equipment. These results suggest that, contrary to what some firms profess, macroeconomic and political risk is not inhibiting the investment behavior of microenterprises. However, insurance may still be of value to help firms cope with shocks when they do occur, but the paper is unable to examine this dimension, because the insurance product did not pay out over the course of the pilot

    Parallel Title: McKenzie, David Evidence on Policies to Increase the Development Impacts of International Migration
    Abstract: International migration offers individuals and their families the potential to experience immediate and large gains in their incomes, and offers a large number of other positive benefits to the sending communities and countries. However, there are also concerns about potential costs of migration, including concerns about trafficking and human rights, a desire for remittances to be used more effectively, and concerns about externalities from skilled workers being lost. As a result there is increasing interest in policies which can enhance the development benefits of international migration and mitigate these potential costs. This paper provides a critical review of recent research on the effectiveness of these policies at three stages of the migration process: pre-departure, during migration, and directed toward possible return. The existing evidence base suggests some areas of policy success: bilateral migration agreements for countries whose workers have few other migration options, developing new savings and remittance products that allow migrants more control over how their money is used, and some efforts to provide financial education to migrants and their families. Suggestive evidence together with theory offers support for a number of other policies, such as lowering the cost of remittances, reducing passport costs, offering dual citizenship, and removing exit barriers to migration. Research offers reasons to be cautious about some policies, such as enforcing strong rights for migrants like high minimum wages. Nevertheless, the paper finds the evidence base to be weak for many policies, with no reliable research on the impact of most return migration programs, nor for whether countries should be trying to induce communal remitting through matching funds

    Parallel Title: McKenzie, David Eliciting Illegal Migration Rates through List Randomization
    Abstract: Most migration surveys do not ask about the legal status of migrants due to concerns about the sensitivity of this question. List randomization is a technique that has been used in a number of other social science applications to elicit sensitive information. This paper trials this technique by adding it to surveys conducted in Ethiopia, Mexico, Morocco, and the Philippines. It shows how, in principal, this can be used both to give an estimate of the overall rate of illegal migration in the population being surveyed, as well as to determine illegal migration rates for subgroups such as more or less educated households. The results suggest that there is some useful information in this method: higher rates of illegal migration in countries where illegal migration is thought to be more prevalent and households who say they have a migrant are more likely to report having an illegal migrant. Nevertheless, some of the other findings also suggest some possible inconsistencies or noise in the conclusions obtained using this method. The authors suggest directions for future attempts to implement this approach in migration surveys

    Parallel Title: De Andrade, Gustavo Henrique A Helping Hand or the Long Arm of the Law?
    Abstract: Many governments have spent much of the past decade trying to extend a helping hand to informal businesses by making it easier and cheaper for them to formalize. Much less effort has been devoted to raising the costs of remaining informal, through increasing enforcement of existing regulations. This paper reports on a field experiment conducted in Belo Horizonte, Brazil, in order to test which government actions work in getting informal firms to register. Firms were randomized to a control group or one of four treatment groups: the first received information about how to formalize; the second received this information and free registration costs along with the use of an accountant for a year; the third group was assigned to receive an enforcement visit from a municipal inspector; while the fourth group was assigned to have a neighboring firm receive an enforcement visit to see if enforcement has spillovers. The analysis finds zero or negative impacts of information and free cost treatments, and a significant but small increase in formalization from inspections. Estimates of the impact of actually receiving an inspection give a 21 to 27 percentage point increase in the likelihood of formalizing. The results show most informal firms will not formalize unless forced to do so, suggesting formality offers little private benefit to them. But the tax revenue benefits to the government of bringing firms of this size into the formal system more than offset the costs of inspections

    Parallel Title: Quy-Toan Do Trade Insulation as Social Protection
    Abstract: In a world with volatile food prices, countries have an incentive to shelter their populations from induced real income shocks. When some agents are net food producers while others are net consumers, there is scope for insurance between the two groups. A domestic social protection scheme would therefore transfer resources away from the former group to the latter in times of high food prices, and do the reverse otherwise. This paper shows that in the presence of consumer preference heterogeneity, implementing the optimal social protection policy can potentially induce higher food price volatility. Such policy indeed generates a counter-cyclical demand shock that amplifies the effects of the underlying food shortage. The results call for a reassessment of food stabilization policies. In particular, the authors urge caution against the systematic condemnation of trade insulation practices

    Abstract: India's huge expansion in rural electrification in the 1980s and 1990s offers lessons for other countries today. The paper examines the long-term effects of household electrification on consumption, labor supply, and schooling in rural India over 1982-99. It finds that household electrification brought significant gains to consumption and earnings, the latter through changes in market labor supply. It finds positive effects on schooling for girls but not for boys. External effects are also evident, whereby households without electricity benefit from village electrification. Wage rates were unaffected. Methodologically, the results suggest sizeable upward biases in past estimates of the gains from electrification associated with how past analyses dealt with geographic effects

    Parallel Title: Murgai, Rinku Is Workfare Cost-Effective against Poverty in a Poor Labor-Surplus Economy?
    Abstract: Workfare schemes impose work requirements on beneficiaries. This has seemed an attractive idea for self-targeting transfers to poor people. This incentive argument does not imply, however, that workfare is more cost-effective against poverty than even poorly-targeted options, given hidden costs of participation. In particular, even poor workfare participants in a labor-surplus economy can be expected to have some forgone income when they take up such a scheme. A survey-based method is used to assess the cost-effectiveness of India's Employment Guarantee Scheme in Bihar. Participants are found to have forgone earnings, although these fall well short of market wages on average. Factoring in these hidden costs, the paper finds that for the same budget, workfare has less impact on poverty than either a basic-income scheme (providing the same transfer to all) or uniform transfers based on the government's below-poverty-line ration cards. For workfare to dominate other options, it would have to work better in practice. Reforms would need to reduce the substantial unmet demand for work, close the gap between stipulated wages and wages received, and ensure that workfare is productive-that the assets created are of value to poor people. Cost-effectiveness would need to be reassessed at the implied higher levels of funding

    Abstract: Significant income gains from migrating from poorer to richer countries have motivated unilateral (source-country) policies facilitating labor emigration. However, their effectiveness is unknown. The authors conducted a large-scale randomized experiment in the Philippines testing the impact of unilaterally facilitating international labor migration. The most intensive treatment doubled the rate of job offers but had no identifiable effect on international labor migration. Even the highest overseas job-search rate that was induced (22 percent) falls far short of the share initially expressing interest in migrating (34 percent). The paper concludes that unilateral migration facilitation will at most induce a trickle, not a flood, of additional emigration

    Parallel Title: Ravallion, Martin Benefit Incidence with Incentive Effects, Measurement Errors and Latent Heterogeneity
    Abstract: Empirical studies of tax and benefit incidence routinely ignore behavioral responses and measurement errors. This paper offers an econometric method of estimating the mean benefit withdrawal rate (marginal tax rate) allowing for incentive effects, measurement errors, and correlated latent heterogeneity in incidence. Under the method's identifying assumptions, a feasible instrumental variables estimator corrects for incentive effects and measurement errors, and provides a bound for the true value when there is correlated incidence heterogeneity. A case study for a large cash transfer program in China indicates that past methods of assessing benefit incidence using either nominal official rates or raw tabulations from survey data are deceptive. The program entails a nominal 100 percent benefit withdrawal rate-a poverty trap. However, the paper finds that the actual rate is much lower, and clearly too low in the light of the literature on optimal income taxation. The paper discusses likely reasons based on the qualitative observations

    Parallel Title: Bruhn, Miriam Using Administrative Data to Evaluate Municipal Reforms
    Abstract: Efforts to make it easier for firms to register formally are the most common form of business regulatory reform over the past decade. While there is evidence that large reforms have resulted in some increases in registration rates, recent experimental evidence suggests very few informal firms choose to register when given information about how to do so. This raises the question of whether it is productive for governments to continue to extend simplification efforts to all firms, especially those in more remote areas where many of the benefits of registering may be reduced. This study uses administrative data to evaluate the impact of Minas Fácil Expresso, a program in the state of Minas Gerais, Brazil, which attempted to expand a business start-up simplification program to more remote municipalities. Using difference-in-differences with 56 months of registration data for 822 municipalities, the analysis finds introducing these units actually led to a reduction in registration rates, and no change in tax revenues. The paper uses this evaluation to illustrate the design choices and issues involved in using administrative data to evaluate reforms, with the goal of also providing a template that can be used for evaluating similar reforms elsewhere

    Parallel Title: Bruhn, Miriam Why is Voluntary Financial Education so Unpopular?
    Abstract: Take-up of voluntary financial education programs is typically extremely low. This paper reports on randomized experiments around a large financial literacy course offered in Mexico City to understand the reasons for low take-up, and to measure the impact of financial education. It documents that the general public displays little interest in such courses and that participation is low even among individuals who express interest in financial education. The paper experimentally investigates barriers to take-up, and finds no impact of relaxing reputational or logistical constraints and no evidence that time inconsistency is the reason for limited participation. Even relatively sizeable monetary incentives get less than 40 percent of interested individuals invited to training to attend. Using a randomized encouragement design, the authors measure the impact of the course on financial knowledge and behavior. Attending training results in a 9 percentage point increase in financial knowledge and a 9 percentage point increase in saving outcomes, but no impact on borrowing behavior. Administrative data indicate that the savings impact is relatively short-lived. The results suggest people are making optimal choices not to attend financial education courses, and point to the limits of using general purpose courses to improve financial behavior for the general population

    Abstract: The majority of microenterprises in most developing countries remain informal despite more than a decade of reforms aimed at making it easier and cheaper for them to formalize. This paper summarizes the evidence on the effects of entry reforms and related policy actions to promote firm formalization. Most of these policies result only in a modest increase in the number of formal firms, if at all. Less is known about the impact of other forms of business regulations on the performance of low-scale enterprises. Most informal firms appear not to benefit on net from formalizing, so ease of formalization alone will not lead to most of them formalizing. Increased enforcement of rules can increase formality. Although there is a fiscal benefit of doing this with larger informal firms, it is unclear whether there is a public rationale for trying to formalize subsistence enterprises

    Abstract: Public knowledge about India's ambitious Employment Guarantee Scheme is low in one of India's poorest states, Bihar, where participation is also unusually low. Is the solution simply to tell people their rights? Or does their lack of knowledge reflect deeper problems of poor people's agency and an unresponsive supply side? This paper reports on an information campaign that was designed and implemented in the form of an entertaining movie to inform people of their rights under the scheme. In randomly-assigned villages, the movie brought significant gains in knowledge and more positive perceptions about the impact of the scheme. But objectively measured employment showed no gain on average, suggesting that the movie created a "groupthink," changing social perceptions about the scheme but not individual efficacy in accessing it. The paper concludes that awareness generation needs to go hand-in-hand with supply-side changes

    Abstract: While self-assessments of welfare have become popular for measuring poverty and estimating welfare effects, the methods can be deceptive given systematic heterogeneity in respondents' scales. Little is known about this problem. This study uses specially-designed surveys in three countries, Tajikistan, Guatemala, and Tanzania, to study scale heterogeneity. Respondents were asked to score stylized vignettes, as well as their own household. Diverse scales are in evidence, casting considerable doubt on the meaning of widely-used summary measures such as subjective poverty rates. Nonetheless, under the identifying assumptions of the study, only small biases are induced in the coefficients on widely-used regressors for subjective poverty and welfare

    Parallel Title: Ravallion, Martin Poor, or Just Feeling Poor?
    Abstract: The challenges faced in calibrating poverty and welfare measures to objective data have long been recognized. Until recently, most economists have resisted a seemingly obvious solution, namely to ask people themselves: "Do you feel poor?" The paper studies the case for and against this approach. It is argued that, while one would not want to use self-assessments as welfare metrics in their own right, there is scope for using such data to help calibrate multidimensional measures. Indeed, the idea of a "social subjective poverty line" (below which people tend to think they are poor, but above which they do not) is arguably the most conceptually appealing way of defining poverty. However, the paper points to a number of concerns that have received insufficient attention, including the choice of covariates, survey design issues, measurement errors, frame-of-reference effects, and latent heterogeneity in personality traits and personal tradeoffs. Directions for future research are identified

    Parallel Title: De Mel, Suresh The Demand for, and Consequences of, Formalization among Informal Firms in Sri Lanka
    Abstract: The majority of firms in most developing countries are informal. The authors of this paper conducted a field experiment in Sri Lanka that provided incentives for informal firms to formalize. Offering only information about the registration process and reimbursement for direct registration costs had no impact on formalization. Adding payments equivalent to one-half to one month's profits for the median firm led to registration of around one-fifth of firms. A larger payment equivalent to two months' median profits induced half the firms to register. The main reasons for not formalizing when offered incentives included issues related to ownership of land and concerns about facing labor taxes in the future. The degree of bureaucracy in the registration process also seems to matter for those with the incentive to register, with response to the incentives higher in Colombo, where the registration process was easier, than in Kandy. Three follow-up surveys, at 15 to 31 months after the intervention, measure the impact of formalizing on these firms. Although mean profits increased, this appears largely due to the experiences of a few firms that grew rapidly, with most firms experiencing no increase in income as a result of formalizing. The authors also find little evidence for most of the channels through which formalization is hypothesized to benefit firms, although formalized firms do advertise more and are more likely to use receipt books. In qualitative interviews owners of formalized firms also feel their businesses have more legitimacy. Finally, formalizing is found to result in a large increase in trust in the state. Their focus is largely on the private costs and benefits of existing firms formalizing. Within their sample they cannot measure broader impacts of formalization on other firms (who may prosper from not having to compete against informal firms not paying taxes), nor impacts of easier formalization on entry of new firms. Nevertheless, our results suggest that although most informal firms do not want to formalize, given the current private costs and benefits of formalizing, policy efforts that lead to relatively modest increases in the net benefits of formalizing would induce a sizeable share of informal firms to formalize

    Abstract: Many more impact evaluations could be done, and at lower unit cost, if evaluators could avoid the need for baseline data using objective socio-economic surveys and rely instead on retrospective subjective questions on how outcomes have changed, asked post-intervention. But would the results be reliable? This paper tests a rapid-appraisal, "shoestring," method using subjective recall for welfare changes. The recall data were collected at the end of a full-scale evaluation of a large poor-area development program in China. Qualitative recalls of how living standards have changed are found to provide only weak and biased signals of the changes in consumption as measured from contemporaneous surveys. Importantly, the shoestring method was unable to correct for the selective placement of the program favoring poor villages. The results of this case study are not encouraging for future applications of the shoestring method, although similar tests are needed in other settings

    Abstract: The authors use an original panel dataset of migrant departures from the Philippines to identify the responsiveness of migrant numbers and wages to gross domestic product shocks in destination countries. They find a large significant elasticity of migrant numbers to gross domestic product shocks at destination, but no significant wage response. This is consistent with binding minimum wages for migrant labor. This result implies that labor market imperfections that make international migration attractive also make migrant flows more sensitive to global business cycles. Difference-in-differences analysis of a minimum wage change for maids confirms that minimum wages bind and demand is price sensitive without these distortions

    Abstract: Relative deprivation, shame and social exclusion can matter to the welfare of people everywhere. The authors argue that such social effects on welfare call for a reconsideration of how we assess global poverty, but they do not support standard measures of relative poverty. The paper argues instead for using a weakly-relative measure as the upper-bound complement to the lower-bound provided by a standard absolute measure. New estimates of global poverty are presented, drawing on 850 household surveys spanning 125 countries over 1981-2008. The absolute line is

    Parallel Title: Ravallion, Martin Benchmarking Global Poverty Reduction
    Abstract: Against what standards should we judge the developing world's overall performance against poverty going forward? The paper proposes two measures, each with both "optimistic" and "ambitious" targets for 2022, 10 years from the time of writing. The first measure is absolute consumption poverty, as judged by what "poverty" means in the poorest countries. The second is a new relative poverty measure, embracing social inclusion needs consistently with national poverty lines. The optimistic benchmark would entail an absolute poverty rate of 9 percent in 2022, and a relative poverty rate of 40 percent. The more ambitious targets would bring the absolute rate down to 3 percent and the relative rate to 33 percent. The optimistic target would maintain the (impressive) progress against poverty of the last 20 years, without global crises to stall that progress. The ambitious target would require about a 1 percentage point higher growth rate for the gross domestic product of the developing world, as long as this did not come with a reduction in the household sector's share or any further increase in overall inequality after its level in 2008. Alternatively, the 3 percent target could be reached at currently expected growth rates but at the lower level of inequality in 1999

    Parallel Title: Dutta, Puja Does India's Employment Guarantee Scheme Guarantee Employment?
    Abstract: In 2005 India introduced an ambitious national anti-poverty program, now called the Mahatma Gandhi National Rural Employment Guarantee Scheme. The program offers up to 100 days of unskilled manual labor per year on public works projects for any rural household member who wants such work at the stipulated minimum wage rate. The aim is to dramatically reduce poverty by providing extra earnings for poor families, as well as empowerment and insurance. If the program worked in practice the way it is designed, then anyone who wanted work on the scheme would get it. However, analysis of data from India's National Sample Survey for 2009/10 reveals considerable un-met demand for work in all states. The authors confirm expectations that poorer families tend to have more demand for work on the scheme, and that (despite the un-met demand) the self-targeting mechanism allows it to reach relatively poor families and backward castes. The extent of the un-met demand is greater in the poorest states-ironically where the scheme is needed most. Labor-market responses to the scheme are likely to be weak. The scheme is attracting poor women into the workforce, although the local-level rationing processes favor men

    Parallel Title: Groh, Matthew Soft Skills or Hard Cash?
    Abstract: Throughout the Middle East, unemployment rates of educated youth have been persistently high and female labor force participation, low. This paper studies the impact of a randomized experiment in Jordan designed to assist female community college graduates find employment. One randomly chosen group of graduates was given a voucher that would pay an employer a subsidy equivalent to the minimum wage for up to 6 months if they hired the graduate; a second group was invited to attend 45 hours of employability skills training designed to provide them with the soft skills employers say graduates often lack; a third group was offered both interventions; and the fourth group forms the control group. The analysis finds that the job voucher led to a 40 percentage point increase in employment in the short-run, but that most of this employment is not formal, and that the average effect is much smaller and no longer statistically significant 4 months after the voucher period has ended. The voucher does appear to have persistent impacts outside the capital, where it almost doubles the employment rate of graduates, but this appears likely to largely reflect displacement effects. Soft-skills training has no average impact on employment, although again there is a weakly significant impact outside the capital. The authors elicit the expectations of academics and development professionals to demonstrate that these findings are novel and unexpected. The results suggest that wage subsidies can help increase employment in the short term, but are not a panacea for the problems of high urban female youth unemployment

    Abstract: The authors conduct a randomized experiment among women in urban Sri Lanka to measure the impact of the most commonly used business training course in developing countries, the Start-and-Improve Your Business program. They work with two representative groups of women: a random sample of women operating subsistence enterprises and a random sample of women who are out of the labor force but interested in starting a business. They track the impacts of two treatments - training only and training plus a cash grant - over two years with four follow-up surveys and find that the short and medium-term impacts differ. For women already in business, training alone leads to some changes in business practices but has no impact on business profits, sales or capital stock. In contrast, the combination of training and a grant leads to large and significant improvements in business profitability in the first eight months, but this impact dissipates in the second year. For women interested in starting enterprises, business training speeds up entry but leads to no increase in net business ownership by the final survey round. Both profitability and business practices of the new entrants are increased by training, suggesting training may be more effective for new owners than for existing businesses. The study also finds that the two treatments have selection effects, leading to entrants being less analytically skilled and poorer

    Parallel Title: McKenzie, David What are we Learning from Business Training and Entrepreneurship Evaluations around the Developing World?
    Abstract: Business training programs are a popular policy option to try to improve the performance of enterprises around the world. The last few years have seen rapid growth in the number of evaluations of these programs in developing countries. This paper undertakes a critical review of these studies with the goal of synthesizing the emerging lessons and understanding the limitations of the existing research and the areas in which more work is needed. It finds that there is substantial heterogeneity in the length, content, and types of firms participating in the training programs evaluated. Many evaluations suffer from low statistical power, measure impacts only within a year of training, and experience problems with survey attrition and measurement of firm profits and revenues. Over these short time horizons, there are relatively modest impacts of training on survivorship of existing firms, but stronger evidence that training programs help prospective owners launch new businesses more quickly. Most studies find that existing firm owners implement some of the practices taught in training, but the magnitudes of these improvements in practices are often relatively modest. Few studies find significant impacts on profits or sales, although a couple of the studies with more statistical power have done so. Some studies have also found benefits to microfinance organizations of offering training. To date there is little evidence to help guide policymakers as to whether any impacts found come from trained firms competing away sales from other businesses versus through productivity improvements, and little evidence to guide the development of the provision of training at market prices. The paper concludes by summarizing some directions and key questions for future studies

    Parallel Title: Alik Lagrange, Arthur Evaluating Workfare When the Work is Unpleasant
    Abstract: Prevailing practices in evaluating workfare programs have ignored the disutility of the type of work done, with theoretically ambiguous implications for the impacts on poverty. In the case of India's National Rural Employment Guarantee Scheme, past assessments have relied solely on household consumption per person as the measure of economic welfare. The paper generalizes this measure to allow for the disutility of casual manual work. The new measure is calibrated to the distribution of the preference parameters implied by maximization of an idiosyncratic welfare function assuming that there is no rationing of the available work. The adjustment implies a substantially more "poor-poor" incidence of participation in the scheme than suggested by past methods. However, the overall impacts on poverty are lower, although still positive. The main conclusions are robust to a wide range of alternative parameter values and to allowing for involuntary unemployment using a sample of (self-declared) un-rationed workers

    Learning from the Experiments That Never Happened : Lessons from Trying to Conduct Randomized Evaluations of Matching Grant Programs in Africa (2012)

    Parallel Title: Campos, Francisco Learning from the Experiments That Never Happened
    Abstract: Matching grants are one of the most common policy instruments used by developing country governments to try to foster technological upgrading, innovation, exports, use of business development services and other activities leading to firm growth. However, since they involve subsidizing firms, the risk is that they could crowd out private investment, subsidizing activities that firms were planning to undertake anyway, or lead to pure private gains, rather than generating the public gains that justify government intervention. As a result, rigorous evaluation of the effects of such programs is important. The authors attempted to implement randomized experiments to evaluate the impact of seven matching grant programs offered in six African countries, but in each case were unable to complete an experimental evaluation. One critique of randomized experiments is publication bias, whereby only those experiments with "interesting" results get published. The hope is to mitigate this bias by learning from the experiments that never happened. This paper describes the three main proximate reasons for lack of implementation: continued project delays, politicians not willing to allow random assignment, and low program take-up; and then delves into the underlying causes of these occurring. Political economy, overly stringent eligibility criteria that do not take account of where value-added may be highest, a lack of attention to detail in "last mile" issues, incentives facing project implementation staff, and the way impact evaluations are funded, and all help explain the failure of randomization. Lessons are drawn from these experiences for both the implementation and the possible evaluation of future projects

    Abstract: Remittances are a major source of external finance for many developing countries but the cost of sending remittances remains high for many migration corridors. International efforts to lower costs by facilitating the entry of new financial products and new cost comparison information sources rely heavily on the financial literacy of migrants. This paper presents the results of a randomized experiment designed to measure the impact of providing financial literacy training to migrants. Training appears to increase financial knowledge and information seeking behavior and reduce the risk of switching to costlier remittance products. But it does not change either the frequency or level of remittances

    Parallel Title: Doi, Yoko Who You Train Matters?
    Abstract: There has long been a concern among policymakers that too much of remittances are consumed and too little saved, limiting the development impact of migration. Financial literacy programs have become an increasingly popular way to try and address this issue, but to date there is no evidence that they are effective in inducing savings among remittance-receiving households, nor is it clear whether such programs are best targeted at the migrant, the remittance receiver, or both. The authors conducted a randomized experiment in Indonesia which allocated migrants and their families to a control group, a migrant-only training group, a family member-only training group, and a training group in which both the migrant and a family member were trained. Three rounds of follow-up surveys are then used to measure impacts on the financial knowledge, behaviors, and remittance and savings outcomes of the remaining household. They find that training both the migrant and the family member together has large and significant impacts on knowledge, behaviors, and savings. Training the family member alone has some positive, but smaller effects, whilst training only the migrant leads to no impacts on the remaining family members. The results show that financial education can have large effects when provided at a teachable moment, but that this impact varies greatly with who receives training

    Parallel Title: Ravallion, Martin On multidimensional indices of poverty
    Abstract: There has been a growing interest in what have come to be termed "multidimensional indices of poverty." Advocates for these new indices correctly point out that command over market goods is not all that matters to peoples' well-being, and that other factors need to be considered when quantifying the extent of poverty and informing policy making for fighting poverty. However, the author argues that there are two poorly understood issues in assessing these indices. First, does one believe that any single index can ever be a sufficient statistic for poverty assessments? Second, when aggregation is called for, should it be done in the space of "attainments," using prices when appropriate, or that of "deprivations," using weights set by the analyst? The paper argues that the goal for future poverty monitoring efforts should be to develop a credible set of multiple indices, spanning the dimensions of poverty most relevant to a specific setting, rather than a single multidimensional index. When weights are needed, they shouldn't be set solely by an analyst measuring poverty. Rather, they should be, as much as possible, consistent with well-informed choices made by poor people

    Parallel Title: McKenzie, David Beyond Baseline and Follow-up
    Abstract: The vast majority of randomized experiments in economics rely on a single baseline and single follow-up survey. If multiple follow-ups are conducted, the reason is typically to examine the trajectory of impact effects, so that in effect only one follow-up round is being used to estimate each treatment effect of interest. While such a design is suitable for study of highly autocorrelated and relatively precisely measured outcomes in the health and education domains, this paper makes the case that it is unlikely to be optimal for measuring noisy and relatively less autocorrelated outcomes such as business profits, household incomes and expenditures, and episodic health outcomes. Taking multiple measurements of such outcomes at relatively short intervals allows the researcher to average out noise, increasing power. When the outcomes have low autocorrelation, it can make sense to do no baseline at all. Moreover, the author shows how for such outcomes, more power can be achieved with multiple follow-ups than allocating the same total sample size over a single follow-up and baseline. The analysis highlights the large gains in power from ANCOVA rather than difference-in-differences when autocorrelations are low and a baseline is taken. The paper discusses the issues involved in multiple measurements, and makes recommendations for the design of experiments and related non-experimental impact evaluations

    Abstract: High-skilled emigration is an emotive issue that in popular discourse is often referred to as brain drain, conjuring images of extremely negative impacts on developing countries. Recent discussions of brain gain, diaspora effects, and other advantages of migration have been used to argue against this, but much of the discussion has been absent of evidence. This paper builds upon a new wave of empirical research to answer eight key questions underlying much of the brain drain debate: 1) What is brain drain? 2) Why should economists care about it? 3) Is brain drain increasing? 4) Is there a positive relationship between skilled and unskilled migration? 5) What makes brain drain more likely? 6) Does brain gain exist? 7) Do high-skilled workers remit, invest, and share knowledge back home? And 8) What do we know about the fiscal and production externalities of brain drain?

    Parallel Title: McKenzie, David How Can We Learn Whether Firm Policies are Working in Africa?
    Abstract: Firm productivity is low in African countries, prompting governments to try a number of active policies to improve it. Yet despite the millions of dollars spent on these policies, we are far from a situation where we know whether many of them are yielding the desired payoffs. This paper establishes some basic facts about the number and heterogeneity of firms in different sub-Saharan African countries and discusses their implications for experimental and structural approaches towards trying to estimate firm policy impacts. It shows that the typical firm program such as a matching grant scheme or business training program involves only 100 to 300 firms, which are often very heterogeneous in terms of employment and sales levels. As a result, standard experimental designs will lack any power to detect reasonable sized treatment impacts, while structural models which assume common production technologies and few missing markets will be ill-suited to capture the key constraints firms face. Nevertheless, the author suggests a way forward which involves focusing on a more homogeneous sub-sample of firms and collecting a lot more data on them than is typically collected

    Parallel Title: Lambert, Sylvie Is it what you Inherited or what you Learnt?
    Abstract: Institutional features of the African setting-large extended families and imperfect credit and land markets-matter to the equity and efficiency roles played by intergenerational linkages. Using original survey data on Senegal that include an individualized measure of consumption, this paper studies the role played by land inheritance, other bequests and parental background as influences on an adult's economic welfare and economic activities. Although intergenerational linkages are evident, the analysis finds a seemingly high degree of mobility across generations, associated with the shift from farm to non-farm sectors and the greater economic activity of women. Male-dominated bequests of land and housing bring little gain to mean consumption and play little role in explaining inequality, although they have effects on the sector of activity. Inheritance of non-land assets and the education and occupation of parents (especially the mother) and their choices about children's schooling are more important to adult welfare than property inheritance. Significant gender inequality in consumption is evident, although it is almost entirely explicable in terms of factors such as education and (non-land) inheritance. There are a number of other pronounced gender differences, with intergenerational linkages coming through the mother rather than the father

    Abstract: Standard models of investment predict that credit-constrained firms should grow rapidly when given additional capital, and that how this capital is provided should not affect decisions to invest in the business or consume the capital. The authors randomly gave cash and in-kind grants to male- and female-owned microenterprises in urban Ghana. Their findings cast doubt on the ability of capital alone to stimulate the growth of female microenterprises. First, while the average treatment effects of the in-kind grants are large and positive for both males and females, the gain in profits is almost zero for women with initial profits below the median, suggesting that capital alone is not enough to grow subsistence enterprises owned by women. Second, for women they strongly reject equality of the cash and in-kind grants; only in-kind grants lead to growth in business profits. The results for men also suggest a lower impact of cash, but differences between cash and in-kind grants are less robust. The difference in the effects of cash and in-kind grants is associated more with a lack of self-control than with external pressure. As a result, the manner in which funding is provided affects microenterprise growth

    Abstract: Development impact calls for knowledgeable development practitioners. How then do the operational staff of the largest development agency value and use its research? Is there an incentive to learn and does it translate into useful knowledge? A new survey reveals that the bulk of the World Bank's senior staff value the Bank's research for their work, and most come to know it well, although a sizable minority have difficulty accessing research to serve their needs. Another group sees little value to research for their work and does not bother to find out about it. Higher perceived value is reflected in greater knowledge about research, though there are frictions in this process. Staff working on poverty, human development and economic policy tend to value and use research more than staff in the more traditional sectors of Bank lending-agriculture and rural development; the latter sectors account for 45 percent of lending but only 15 percent of staff highly familiar with Bank research. Without stronger incentives for learning and more relevant and accessible research products, it appears likely that this lag in demand for research by the traditional sectors will persist

First, links from blogs cause a striking increase in the number of abstract views and downloads of economics papers. Second, blogging raises the profile of the blogger (and his or her institution) and boosts their reputation above economists with similar publication records. Finally, a blog can transform attitudes about some of the topics it covers

    Parallel Title: Ravallion, Martin On the Implications of Essential Heterogeneity for Estimating Causal Impacts Using Social Experiments
    Abstract: Randomized control trials are sometimes used to estimate the aggregate benefit from some policy or program. To address the potential bias from selective take-up, the randomization is used as an instrumental variable for treatment status. Does this (popular) method of impact evaluation help reduce the bias when take-up depends on unobserved gains from take up? Such "essential heterogeneity" is known to invalidate the instrumental variable estimator of mean causal impact, though one still obtains another parameter of interest, namely mean impact amongst those treated. However, if essential heterogeneity is the only problem then the naïve (ordinary least squares) estimator also delivers this parameter; there is no gain from using randomization as an instrumental variable. On allowing the heterogeneity to also alter counterfactual outcomes, the instrumental variable estimator may well be more biased for mean impact than the naïve estimator. Examples are given for various stylized programs, including a training program that attenuates the gains from higher latent ability, an insurance program that compensates for losses from unobserved risky behavior and a microcredit scheme that attenuates the gains from access to other sources of credit. Practitioners need to think carefully about the likely behavioral responses to social experiments in each context

    Parallel Title: Ravallion, Martin The two poverty enlightenments
    Abstract: Word searches of Google's library of digitized books suggest that there have been two “Poverty Enlightenments” since 1700, one near the end of the 18th century and the second near the end of the 20th. The historical literature suggests that only the second came with a widespread belief that poverty could and should be eliminated. After the first Poverty Enlightenment, references to “poverty” (as a percentage of all words) were on a trend decline until 1960, after which there was a striking resurgence of interest, which came with rising attention to economics and more frequent references to both general and specific policies relevant to poverty. Developing countries also became more prominent in the literature. Both Enlightenments came with greater attention to human rights. The written record reflects the push-back against government intervention and the retreat from leftist economics and politics since the late 1970s. Although many debates from 200 years ago continue today, there is little sign that the modern revival of the classical 19th century views on the limitations of government has come with a revival of the complacency about poverty that was common early in that century

    Parallel Title: Dang, Hai-Anh Using Repeated Cross-Sections to Explore Movements into and Out of Poverty
    Abstract: Movements in and out of poverty are of core interest to both policymakers and economists. Yet the panel data needed to analyze such movements are rare. In this paper, the authors build on the methodology used to construct poverty maps to show how repeated cross-sections of household survey data can allow inferences to be made about movements in and out of poverty. They illustrate that the method permits the estimation of bounds on mobility, and provide non-parametric and parametric approaches to obtaining these bounds. They test how well the method works on data sets for Vietnam and Indonesia where we are able to compare our method to true panel estimates. The results are sufficiently encouraging to offer the prospect of some limited, basic, insights into mobility and poverty duration in settings where historically it was judged that the data necessary for such analysis were unavailable

    Parallel Title: Woodruff, Christopher Enterprise Recovery Following Natural Disasters
    Abstract: Using data from surveys of enterprises in Sri Lanka after the December 2004 tsunami, the authors undertake the first microeconomic study of the recovery of the private firms in a developing country following a major natural disaster. Disaster recovery in low-income countries is characterized by the prevalence of relief aid rather than of insurance payments; the data show this distinction has important consequences. The data indicate that aid provided directly to households correlates reasonably well with reported losses of household assets, but is uncorrelated with reported losses of business assets. Business recovery is found to be slower than commonly assumed, with disaster-affected enterprises lagging behind unaffected comparable firms more than three years after the disaster. Using data from random cash grants provided by the project, the paper shows that direct aid is more important in the recovery of enterprises operating in the retail sector than for those operating in the manufacturing and service sectors

    Accounting for Selectivity and Duration-Dependent Heterogeneity When Estimating the Impact of Emigration On Incomes and Poverty in Sending Areas (2010)

    Parallel Title: Stillman, Steven Accounting for Selectivity and Duration-Dependent Heterogeneity When Estimating the Impact of Emigration On Incomes and Poverty in Sending Areas
    Abstract: The impacts of international emigration and remittances on incomes and poverty in sending areas are increasingly studied with household survey data. But comparing households with and without emigrants is complicated by a triple-selectivity problem: first, households self-select into emigration; second, in some emigrant households everyone moves while others leave members behind; and third, some emigrants choose to return to the origin country. Allowing for duration-dependent heterogeneity introduces a fourth form of selectivity - one must now worry not just about whether households migrate, but also when they do so. This paper clearly sets out these selectivity issues and their implications for existing migration studies, and then addresses them by using survey data designed specifically to take advantage of a randomized lottery that determines which applicants to the over-subscribed Samoan Quota may immigrate to New Zealand. The analysis compares incomes and poverty rates among left behind members in households in Samoa that sent Samoan Quota emigrants with those for members of similar households that were unsuccessful in the lottery. Policy rules control who can accompany the principal migrant, providing an instrument to address the second selectivity problem, while differences among migrants in which year their ballot was selected allow for estimation of duration effects. The authors find that migration reduced poverty among former household members, but they also find suggestive evidence that this effect may be short-lived as both remittances and agricultural income are negatively related to the duration that the migrant has been abroad

Yet currently favored measures lack a clear conceptual foundation and are known to have counter-intuitive properties. The authors propose a new approach that is grounded on a theoretical "influence function," representing explicit prior beliefs about how citations reflect influence. They provide conditions for robust qualitative comparisons of influence - conditions that can be implemented using readily-available data. An example is provided using the economics publication records of selected universities and the World Bank

    Parallel Title: McKenzie, David Experimental Approaches in Migration Studies
    Abstract: The decision of whether or not to migrate has far-reaching consequences for the lives of individuals and their families. But the very nature of this choice makes identifying the impacts of migration difficult, since it is hard to measure a credible counterfactual of what the person and their household would have been doing had migration not occurred. Migration experiments provide a clear and credible way for identifying this counterfactual, and thereby allowing causal estimation of the impacts of migration. The authors provide an overview and critical review of the three strands of this approach: policy experiments, natural experiments, and researcher-led field experiments. The purpose is to introduce readers to the need for this approach, give examples of where it has been applied in practice, and draw out lessons for future work in this area

    Parallel Title: Ravallion, Martin Troubling tradeoffs in the Human Development Index
    Abstract: The 20th Human Development Report has introduced a new version of its famous Human Development Index (HDI). The HDI aggregates country-level attainments in life expectancy, schooling and income per capita. Each year's rankings by the HDI are keenly watched in both rich and poor countries. The main change in the 2010 HDI is that it relaxes its past assumption of perfect substitutability between its three components. However, most users will probably not realize that the new HDI has also greatly reduced its implicit weight on longevity in poor countries, relative to rich ones. A poor country experiencing falling life expectancy due to (say) a collapse in its health-care system could still see its HDI improve with even a small rate of economic growth. By contrast, the new HDI's valuations of the gains from extra schooling seem unreasonably high - many times greater than the economic returns to schooling. These troubling tradeoffs could have been largely avoided using a different aggregation function for the HDI, while still allowing imperfect substitution. While some difficult value judgments are faced in constructing and assessing the HDI, making its assumed tradeoffs more explicit would be a welcome step

    Parallel Title: McKenzie, David The development impact of a best practice seasonal worker policy
    Abstract: Seasonal migration programs are widely used around the world, and are increasingly seen as offering a potential “triple-win”- benefiting the migrant, sending country, and receiving country. Yet there is a dearth of rigorous evidence as to their development impact, and concerns about whether the time periods involved are too short to realize much in the way of benefits, and whether poorer, less skilled households actually get to participate in such programs. This paper studies the development impacts of a recently introduced seasonal worker program that has been deemed to be “best practice.” New Zealand's Recognized Seasonal Employer program was launched in 2007 with an explicit focus on development in the Pacific alongside the aim of benefiting employers at home. A multi-year prospective evaluation allows measurement of the impact of participation in this program on households and communities in Tonga and Vanuatu. Using a matched difference-in-differences analysis based on detailed surveys fielded before, during, and after participation, the authors find that the Recognized Seasonal Employer program has indeed had largely positive development impacts. It has increased income and consumption of households, allowed households to purchase more durable goods, increased the subjective standard of living, and had additional benefits at the community level. It also increased child schooling in Tonga. This should rank it among the most effective development policies evaluated to date. The policy was designed as a best practice example based on lessons elsewhere, and now should serve as a model for other countries to follow

    Parallel Title: Morten, Melanie The Remitting Patterns of African Migrants in the OECD
    Abstract: Recorded remittances to Africa have grown dramatically over the past decade. Yet data limitations still mean relatively little is known about which migrants remit, how much they remit, and how their remitting behavior varies with gender, education, income levels, and duration abroad. This paper constructs the most comprehensive remittance database on immigrants in the OECD currently available, containing microdata on more than 12,000 African immigrants. Using this microdata the authors establish several basic facts about the remitting patterns of Africans, and then explore how key characteristics of policy interest relate to remittance behavior. Africans are found to remit twice as much on average as migrants from other developing countries, and those from poorer African countries are more likely to remit than those from richer African countries. Male migrants remit more than female migrants, particularly among those with a spouse remaining in the home country; more-educated migrants remit more than less educated migrants; and although the amount remitted increases with income earned, the gradient is quite flat over a large range of income. Finally, there is little evidence that the amount remitted decays with time spent abroad, with reductions in the likelihood of remitting offset by increases in the amount remitted conditional on remitting

    Price Levels and Economic Growth : Making Sense of the PPP Changes Between ICP Rounds (2010)

    Parallel Title: Ravallion, Martin Price Levels and Economic Growth
    Abstract: To the surprise of many observers, the 2005 International Comparison Program (ICP) found substantially higher purchasing power parity (PPP) rates, relative to market exchange rates, in most developing countries. For example, China’s price level index - the ratio of its PPP to its exchange rate - doubled between the 1993 and 2005 rounds of the ICP. The paper tries to explain the observed changes in PPPs. Consistently with the Balassa-Samuelson model, evidence is found of a "dynamic Penn effect," whereby more rapidly growing economies experience steeper increases in their price level index. This effect has been even stronger for initially poorer countries. Thus the widely-observed static (cross-sectional) Penn effect has been attenuated over time. On also taking account of exchange rate changes and prior participation in the ICP’s price surveys, 99 percent of the variance in the observed changes in PPPs is explicable. Using a nested test, the World Bank’s longstanding method of extrapolating PPPs between ICP rounds using inflation rates alone is out performed by the model proposed in this paper

    Abstract: The World Bank has produced a huge volume of books and papers on development - 20,000 publications spanning decades, but growing appreciably since 1990. This paper finds evidence that many of these publications have influenced development thinking, as indicated by the citations found using Google Scholar and in bibliographic data bases. However, the authors also find that a non-negligible share of the Bank's publications have received no citations, suggesting that they have had little scholarly influence, though they may well have had influence on non-academic audiences. Individually-authored journal articles have been the main channel for scholarly influence. The volume of the Bank's research output on development is greater than that of any of the comparator institutions identified, including other international agencies and the top universities in economics. The bibliometric indicators of the quality and influence of the Bank's portfolio of scholarly publications are on a par with, or better than, most of the top universities

    Parallel Title: McKenzie, David The Economic Consequences of "Brain Drain" of the Best and Brightest
    Abstract: Brain drain has long been a common concern for migrant-sending countries, particularly for small countries where high-skilled emigration rates are highest. However, while economic theory suggests a number of possible benefits, in addition to costs, from skilled emigration, the evidence base on many of these is very limited. Moreover, the lessons from case studies of benefits to China and India from skilled emigration may not be relevant to much smaller countries. This paper presents the results of innovative surveys which tracked academic high-achievers from five countries to wherever they moved in the world in order to directly measure at the micro level the channels through which high-skilled emigration affects the sending country. The results show that there are very high levels of emigration and of return migration among the very highly skilled; the income gains to the best and brightest from migrating are very large, and an order of magnitude or more greater than any other effect; there are large benefits from migration in terms of postgraduate education; most high-skilled migrants from poorer countries send remittances; but that involvement in trade and foreign direct investment is a rare occurrence. There is considerable knowledge flow from both current and return migrants about job and study opportunities abroad, but little net knowledge sharing from current migrants to home country governments or businesses. Finally, the fiscal costs vary considerably across countries, and depend on the extent to which governments rely on progressive income taxation

    Parallel Title: Ravallion, Martin Mashup indices of development
    Abstract: Countries are increasingly being ranked by some new "mashup index of development," defined as a composite index for which existing theory and practice provides little or no guidance to its design. Thus the index has an unusually large number of moving parts, which the producer is essentially free to set. The parsimony of these indices is often appealing - collapsing multiple dimensions into just one, yielding unambiguous country rankings, and possibly reducing concerns about measurement errors in the component series. But the meaning, interpretation and robustness of these indices are often unclear. If they are to be properly understood and used, more attention needs to be given to their conceptual foundations, the tradeoffs they embody, the contextual factors relevant to country performance, and the sensitivity of the implied rankings to changing the data and weights. In short, clearer warning signs are needed for users. But even then, nagging doubts remain about the value-added of mashup indices, and their policy relevance, relative to the "dashboard" alternative of monitoring the components separately. Future progress in devising useful new composite indices of development will require that theory catches up with measurement practice

The authors conducted an experiment in India that tested the sensitivity of elicited expectations to variations in three facets of the elicitation methodology: the number of beans, the design of the support (pre-determined or self-anchored), and the ordering of questions. The results show remarkable robustness to variations in elicitation design. Nevertheless, the added precision offered by using more beans and a larger number of intervals with a predetermined support improves accuracy

    Abstract: Until recently rigorous impact evaluations have been rare in the area of finance and private sector development. One reason for this is the perception that many policies and projects in this area lend themselves less to formal evaluations. However, a vanguard of new impact evaluations on areas as diverse as fostering microenterprise growth, microfinance, rainfall insurance, and regulatory reform demonstrates that in many circumstances serious evaluation is possible. The purpose of this paper is to synthesize and distil the policy and implementation lessons emerging from these studies, use them to demonstrate the feasibility of impact evaluations in a broader array of topics, and thereby help prompt new impact evaluations for projects going forward

    Parallel Title: Gibson, John The Impacts of International Migration On Remaining Household Members
    Abstract: The impacts of international migration on development in the sending countries, and especially the effects on remaining household members, are increasingly studied. However, comparisons of households in developing countries with and without migrants are complicated by a double-selectivity problem: households self-select into migration, and among households involved in migration, some send a subset of members with the rest remaining while other households migrate en masse. The authors address these selectivity issues using the randomization provided by an immigration ballot under the Pacific Access Category of New Zealand’s immigration policy. They survey applicants to the 2002-05 ballots in Tonga and compare outcomes for the remaining household members of emigrants with those for members of similar households that were unsuccessful in the ballots. The immigration laws determine which household members can accompany the principal migrant, providing an instrument to address the second selectivity issue. Using this natural experiment, the authors examine the myriad impacts that migration has on remaining household members, focussing on labor supply, income, durable assets, financial service usage, diet, and physical and mental health. The analysis uses multiple hypothesis testing procedures to examine which impacts are robust. The findings indicate that the overall impact on households left behind is largely negative. The findings also reveal evidence that both sources of selectivity matter, leading studies that fail to adequately address them to misrepresent the impact of migration

    Parallel Title: Bollard, Albert Remittances and the Brain Drain Revisited
    Abstract: Two of the most salient trends surrounding the issue of migration and development over the past two decades are the large rise in remittances, and an increased flow of skilled migration. However, recent literature based on cross-country regressions has claimed that more educated migrants remit less, leading to concerns that further increases in skilled migration will hamper remittance growth. This paper revisits the relationship between education and remitting behavior using microdata from surveys of immigrants in 11 major destination countries. The data show a mixed pattern between education and the likelihood of remitting, and a strong positive relationship between education and the amount remitted conditional on remitting. Combining these intensive and extensive margins gives an overall positive effect of education on the amount remitted. The microdata then allow investigation as to why the more educated remit more. The analysis finds that the higher income earned by migrants, rather than characteristics of their family situations, explains much of the higher remittances

    Parallel Title: Gibson, John The Microeconomic Determinants of Emigration and Return Migration of the Best and Brightest
    Abstract: A unique survey which tracks worldwide the best and brightest academic performers from three Pacific countries is used to assess the extent of emigration and return migration among the very highly skilled, and to analyze, at the microeconomic level, the determinants of these migration choices. Although the estimates indicate that the income gains from migration are very large, not everyone migrates and many return. Within this group of highly skilled individuals, the emigration decision is found to be most strongly associated with preference variables such as risk aversion, patience, and choice of subjects in secondary school, and not strongly linked to either liquidity constraints or the gain in income to be had from migrating. Likewise, the decision to return is strongly linked to family and lifestyle reasons, rather than to the income opportunities in different countries. Overall the data show a relatively limited role for income maximization in distinguishing migration propensities among the very highly skilled, and point to the need to pay more attention to other components of the utility maximization decision

    Parallel Title: Ravallion, Martin Why Don't We See Poverty Convergence?
    Abstract: We are not seeing faster progress against poverty amongst the poorest developing countries. Yet this is implied by widely accepted "stylized facts" about the development process. The paper tries to explain what is missing from those stylized facts. Consistently with models of economic growth incorporating borrowing constraints, the analysis of a new data set for 100 developing countries reveals an adverse effect on consumption growth of high initial poverty incidence at a given initial mean. A high incidence of poverty also entails a lower subsequent rate of progress against poverty at any given growth rate (and poor countries tend to experience less steep increases in poverty during recessions). Thus, for many poor countries, the growth advantage of starting out with a low mean ("conditional convergence") is lost due to their high poverty rates. The size of the middle class - measured by developing-country, not Western, standards - appears to be an important channel linking current poverty to subsequent growth and poverty reduction. However, high current inequality is only a handicap if it entails a high incidence of poverty relative to mean consumption

    Parallel Title: Ravallion, Martin A Comparative Perspective On Poverty Reduction in Brazil, China and India
    Abstract: Brazil, China and India have seen falling poverty in their reform periods, but to varying degrees and for different reasons. History left China with favorable initial conditions for rapid poverty reduction through market-led economic growth; at the outset of the reform process there were ample distortions to remove and relatively low inequality in access to the opportunities so created, though inequality has risen markedly since. By concentrating such opportunities in the hands of the better off, prior inequalities in various dimensions handicapped poverty reduction in both Brazil and India. Brazil's recent success in complementing market-oriented reforms with progressive social policies has helped it achieve more rapid poverty reduction than India, although Brazil has been less successful in terms of economic growth. In the wake of its steep rise in inequality, China might learn from Brazil's success with such policies. India needs to do more to assure that poor people are able to participate in both the country's growth process and its social policies; here there are lessons from both China and Brazil. All three countries have learned how important macroeconomic stability is to poverty reduction

    Parallel Title: Datt, Gaurav Has India's Economic Growth Become More Pro-Poor in the Wake of Economic Reforms ?
    Abstract: The extent to which India's poor have benefited from the country’s economic growth has long been debated. This paper revisits the issues using a new series of consumption-based poverty measures spanning 50 years, and including a 15-year period after economic reforms began in earnest in the early 1990s. Growth has tended to reduce poverty, including in the post-reform period. There is no robust evidence that the responsiveness of poverty to growth has increased, or decreased, since the reforms began, although there are signs of rising inequality. The impact of growth is higher for poverty measures that reflect distribution below the poverty line, and it is higher using growth rates calculated from household surveys than national accounts. The urban-rural pattern of growth matters to the pace of poverty reduction. However, in marked contrast to the pre-reform period, the post-reform process of urban economic growth has brought significant gains to the rural poor as well as the urban poor

    Parallel Title: Montalvo, Jose G The Pattern of Growth and Poverty Reduction in China
    Abstract: China has seen a huge reduction in the incidence of extreme poverty since the economic reforms that started in the late 1970s. Yet, the growth process has been highly uneven across sectors and regions. The paper tests whether the pattern of China´s growth mattered to poverty reduction using a new provincial panel data set constructed for this purpose. The econometric tests support the view that the primary sector (mainly agriculture) has been the main driving force in poverty reduction over the period since 1980. It was the sectoral unevenness in the growth process, rather than its geographic unevenness, that handicapped poverty reduction. Yes, China has had great success in reducing poverty through economic growth, but this happened despite the unevenness in its sectoral pattern of growth. The idea of a trade-off between these sectors in terms of overall progress against poverty in China turns out to be a moot point, given how little evidence there is of any poverty impact of non-primary sector growth, controlling for primary-sector growth. While the non-primary sectors were key drivers of aggregate growth, it was the primary sector that did the heavy lifting against poverty

    Parallel Title: Ravallion, Martin Do Poorer Countries Have Less Capacity for Redistribution?
    Abstract: Development aid and policy discussions often assume that poorer countries have less internal capacity for redistribution in favor of their poorest citizens. The assumption is tested using data for 90 developing countries. The capacity for redistribution is measured by the marginal tax rate on those who are not poor by rich-country standards that is needed to cover the poverty gap or to provide a poverty-level of basic income, judged by developing-country standards. For most (but not all) countries with annual consumption per capita under

    Abstract: At the outset of China's reform period, the country had a far higher poverty rate than for Africa as a whole. Within five years that was no longer true. This paper tries to explain how China escaped from a situation in which extreme poverty persisted due to failed and unpopular policies. While acknowledging that Africa faces constraints that China did not, and that context matters, two lessons stand out. The first is the importance of productivity growth in smallholder agriculture, which will require both market-based incentives and public support. The second is the role played by strong leadership and a capable public administration at all levels of government
