    Keywords: Bayesian Impact Evaluation ; Competition Policy ; Competitiveness and Competition Policy ; Economic Theory and Research ; Export Competitiveness ; International Economics and Trade ; Macroeconomics and Economic Growth ; Management ; Prior Elicitation ; Private Sector Development ; Randomized Experiment ; Social Policy Evaluation Method
    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

    Keywords: Counterfactual Reasoning ; Family Formation ; Human Rights ; International Economics and Trade ; International Migration ; Law and Development ; Macroeconomics and Economic Growth ; Migrant Policy ; Migrants Families ; Migration ; Remittances ; Status Quo Bias
    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

    Keywords: Development Economics and Aid Effectiveness ; Firm Support ; Green Growth Agenda ; Impact Evaluation ; Industrial Economics ; Industrial Policy ; Industry ; Macroeconomic Policy ; Macroeconomics and Economic Growth ; Subsidized Loans
    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

    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

    Keywords: Attachment To Home ; Benefits of Urbanization ; Communities and Human Settlements ; Constraints That Limit Movement ; Economics of Migration ; Health, Nutrition and Population ; Human Migrations and Resettlements ; Internal Relocation ; International Economics and Trade ; International Migration ; Mental Health ; Migration Policy ; Psychological Uncertainty of Relocation ; Wealth and Wellbeing
    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 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

    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

    Parallel Title: Erscheint auch als Print Version: Bah, Tijan L How has COVID-19 Affected the Intention to Migrate via the Backway to Europe and to a Neighboring African Country? Survey Evidence and a Salience Experiment in the Gambia
    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: 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

    Keywords: Destination Choice ; Employment and Unemployment ; International Economics and Trade ; International Migration ; Lab Experiment ; Migrant Selection ; Poverty Reduction ; Social Protections and Labor ; Wages, Compensation and Benefits
    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

    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: McKenzie, David Impact Assessments in Finance and Private Sector Development
    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: 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

    Abstract: Is the vast army of the self-employed in low income countries a source of employment generation? This paper uses data from surveys in Sri Lanka to compare the characteristics of own account workers (non-employers) with wage workers and with owners of larger firms. The authors use a rich set of measures of background, ability, and attitudes, including lottery experiments measuring risk attitudes. Consistent with the International Labor Organization's views of the self employed (represented by Tokman), the analysis finds that two-thirds to three-quarters of the own account workers have characteristics which are more like wage workers than larger firm owners. This suggests the majority of the own account workers are unlikely to become employers. Using a two and a half year panel of enterprises, the authors show that the minority of own account workers who are more like larger firm owners are more likely to expand by adding paid employees. The results suggest that finance is not the sole constraint to growth of microenterprises, and provides an explanation for the low rates of growth of enterprises supported by microlending

    Abstract: This paper estimates the impact of registering for taxes on firm profits in Bolivia, the country with the highest levels of informality in Latin America. A new survey of micro and small firms enables the authors to control for a rich set of measures of owner ability and business motivations that can affect both profits and the decision to formalize. The paper identifies the impact of tax registration on business profitability using the distance of a firm from the tax office where registration occurs, conditional on the distance to the city center, as an instrument for registration. Proximity to the tax office provides firms with more information about registration, but is argued to not directly affect profits. The findings show that tax registration leads to significantly higher profits for the firms that the instrument affects. However, there is also evidence of heterogeneous effects of tax formality on profits. Tax registration is found to increase profits for the mid-size firms in the sample, but to lower profits for both the smaller and larger firms, in contrast to the standard view that formality increases profits. The analysis shows that owners of large firms who have managed to stay informal have higher entrepreneurial ability than formal firm owners, in contrast to the standard view (correct among smaller firms) that informal firm owners have low ability

    Abstract: Distance and location are important determinants of many choices that economists study. While these variables can sometimes be obtained from secondary data, economists often rely on information that is self-reported by respondents in surveys. These self-reports are used especially for the distance from households or community centers to various features such as roads, markets, schools, clinics, and other public services. There is growing evidence that self-reported distance is measured with error and that these errors are correlated with outcomes of interest. In contrast to self-reports, the Global Positioning System (GPS) can determine almost exact location (typically within 15 meters). The falling cost of GPS receivers (typically below US

    Abstract: A large share of the world's poor is self-employed. Accurate measurement of profits from microenterprises is therefore critical for studying poverty and inequality, measuring the returns to education, and evaluating the success of microfinance programs. But a myriad of problems plague the measurement of profits. The authors report on a variety of different experiments conducted to better understand the importance of some of these problems and to draw recommendations for collecting profit data. In particular, they (1) examine how far we can reconcile self-reported profits and reports of revenue minus expenses through more detailed questions; (2) examine recall errors in sales and report on the results of experiments which randomly allocated account books to firms; and (3) ask firms how much firms like theirs underreport sales in surveys like this, and have research assistants observe the firms at random times 15-16 times during a month to provide measures for comparison. The authors conclude that firms underreport revenues by about 30 percent, that account diaries have significant effects on both revenues and expenses but not on profits, and that simply asking profits provides a more accurate measure of firm profits than detailed questions on revenues and expenses

    Abstract: People migrate to improve their well-being, whether through an expansion of economic and social opportunities or a reduction in persecution. Yet a large literature suggests that migration can be a stressful process, with potentially negative impacts on mental health, reducing the net benefits of migration. However, to truly understand the effect of migration on mental health one must compare the mental health of migrants to what their mental health would have been had they stayed in their home country. The existing literature is not able to do this and typically settles for comparing the mental health of migrants to that of natives in the destination country, which takes no account of any pre-existing differences between these groups. This paper overcomes the selection problems affecting previous studies of the effect of migration on mental health by examining a migrant lottery program. New Zealand allows a quota of Tongans to immigrate each year with a lottery used to choose among the excess number of applicants. A unique survey conducted by the authors in these two countries allows experimental estimates of the mental health effects of migration to be obtained by comparing the mental health of migrants who were successful applicants in the lottery to the mental health of those who applied to migrate under the quota, but whose names were not drawn in the lottery. Migration is found to lead to improvements in mental health, particularly for women and those with poor mental health in their home country

    Abstract: Millions of people emigrate every year in search of better economic and social opportunities. Anecdotal evidence suggests that emigrants may have over-optimistic expectations about the incomes they can earn abroad, resulting in excessive migration pressure, and in disappointment among those who do migrate. Yet there is almost no statistical evidence on how accurately these emigrants predict the incomes that they will earn working abroad. In this paper the authors combine a natural emigration experiment with unique survey data on would-be emigrants' probabilistic expectations about employment and incomes in the migration destination. Their procedure enables them to obtain moments and quantiles of the subjective distribution of expected earnings in the destination country. The authors find a significant underestimation of both unconditional and conditional labor earnings at all points in the distribution. This underestimation appears driven in part by potential migrants placing too much weight on the negative employment experiences of some migrants, and by inaccurate information flows from extended family, who may be trying to moderate remittance demands by understating incomes

    Abstract: Small and informal firms account for a large share of employment in developing countries. The rapid expansion of microfinance services is based on the belief that these firms have productive investment opportunities and can enjoy high returns to capital if given the opportunity. However, measuring the return to capital is complicated by unobserved factors such as entrepreneurial ability and demand shocks, which are likely to be correlated with capital stock. The authors use a randomized experiment to overcome this problem and to measure the return to capital for the average microenterprise in their sample, regardless of whether they apply for credit. They accomplish this by providing cash and equipment grants to small firms in Sri Lanka, and measuring the increase in profits arising from this exogenous (positive) shock to capital stock. After controlling for possible spillover effects, the authors find the average real return to capital to be 5.7 percent a month, substantially higher than the market interest rate. They then examine the heterogeneity of treatment effects to explore whether missing credit markets or missing insurance markets are the most likely cause of the high returns. Returns are found to vary with entrepreneurial ability and with measures of other sources of cash within the household, but not to vary with risk aversion or uncertainty

    Abstract: This paper reviews common challenges faced by researchers interested in measuring the impact of migration and remittances on income, poverty, inequality, and human capital (or, in general, "welfare") as well as difficulties confronting development practitioners in converting this research into policy advice. On the analytical side, the paper discusses the proper formulation of a research question, the choice of the analytical tools, as well as the interpretation of the results in the presence of pervasive endogeneity in all decisions surrounding migration. Particular attention is given to the use of instrumental variables in migration research. On the policy side, the paper argues that the private nature of migration and remittances implies a need to carefully spell out the rationale for interventions. It also notices the lack of good migration data and proper evaluations of migration-related government policies. The paper focuses mainly on microeconomic evidence about international migration, but much of the discussion extends to other settings as well

    Abstract: The authors examine the role of migration networks in determining self-selection patterns of Mexico-U.S. migration. They first present a simple theoretical framework showing how such networks impact on migration incentives at different education levels and, consequently, how they are likely to affect the expected skill composition of migration. Using survey data from Mexico, the authors then show that the probability of migration is increasing with education in communities with low migrant networks, but decreasing with education in communities with high migrant networks. This is consistent with positive self-selection of migrants being driven by high migration costs, and with negative self-selection of migrants being driven by lower returns to education in the U.S. than in Mexico
