    Keywords: Carbon Policy and Trading ; Carbon Tax Revenue Distribution ; Climate Change ; Distributional Impact ; Environment ; GDP Reduction ; General Equilibrium Model ; Paris Climate Agreement ; Progressive Tax
    Abstract: Developing countries are increasingly giving attention to carbon pricing to reduce their emissions, particularly in meeting their nationally determined contribution under the Paris Climate Agreement. However, they would like to understand the potential economic, distributional, and environmental impacts of carbon pricing policies before they consider implementation. Using a computable general equilibrium model of Ethiopia, this study examines the effects of a hypothetical carbon tax (USD 20/total carbon dioxide) under several alternative schemes to recycle carbon tax revenue to the economy. The study finds that a carbon tax would be regressive in all schemes considered except those when the tax revenue is recycled, as a cash transfer, to household income groups either equally or inversely proportional to their incomes. The schemes that make the carbon tax progressive also cause a higher reduction of carbon dioxide emissions, thereby ensuring the alignment of equity and environmental outcomes of the carbon tax. However, these schemes are not necessarily economically efficient because they cause higher reductions of gross domestic product compared to other options considered

    Keywords: Climate Change Mitigation and Green House Gases ; Competitiveness and Competition Policy ; Emissions Policy ; Emissions Tax ; Environment ; Environmental Economics ; Environmental Economics and Policies ; Green Technology ; Green Technology Research ; Imperfect Competition ; Innovation ; Local Adaptation ; Private Sector Development ; Public Firms ; State-Owned Enterprises
    Abstract: Green technologies, such as renewable energy, often require adaptation to local conditions, such as high humidity, high altitudes or the specifics of a country's infrastructure, to achieve a maximal technical efficiency and a long lifetime of investments. This poses a problem for green technology transitions, as adaptations usually imply protected intellectual property rights and thus market imperfections that can lead to higher prices and thereby a lower uptake of the green technology. An alternative could be to use state-owned enterprises to adapt and promote green technologies, such as public utilities, which are more easily steered toward pursuing societal objectives. However, many empirical studies find state-owned enterprises to be less efficient. This theoretical contribution investigates the question whether a green technology transition that requires research and development is better driven by private firms or state-owned enterprises. The paper adapts a model to this setting, derives possible market outcomes from this model, investigates research and development and production decisions of private firms and a state-owned enterprise, and compares the welfare implications of the two options. The results show that there are cases where the cost inefficiency of the state-owned enterprise dominates (for example, if competition of directly importing firms reduces possible markups of private innovating firms), but also cases where a state-owned enterprise is the preferred choice (for example, if several private firms would adapt the technology, causing over-innovation). Most importantly, this is not solely a question of comparing costs, but rather of comparing market outcomes. For example, the use of a state-owned enterprise can avoid the often found problem of overinvestment in research and development by private firms and, in many cases, a state-owned enterprise will induce a wider diffusion of the green technology

    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

    Keywords: Determinants, Infrasturcture Investment ; Government Expenditure ; Infrastructure Development ; Infrastructure Economics and Finance ; Infrastructure Expenditure
    Abstract: The literature suggests that one of the main factors behind the interstate inequality in economic development in India is the variation in the level of infrastructure development. However, unequal infrastructure development across the Indian States is less understood. This study empirically analyzes various factors (economic, fiscal, demographic, social, institutional, and political) to explain interstate infrastructure inequality using a panel data set for 18 states in India between 2004 and 2020. Employing the principal component analysis technique, three separate infrastructure indices are developed for physical, social, and financial infrastructures. The relationship of each index with its explanatory variables is estimated using System Generalized Method of Moments. The results show that economic factors? including economic performance, financial development, investment, and economic structure?are more influential on physical infrastructure. For social infrastructure, in addition to economic factors, fiscal and demographic factors are more influential. Meanwhile, economic and demographic factors are found to drive financial infrastructure. Financial development fosters physical infrastructure, while its impact on social infrastructure is weak

    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: Distributed photovoltaics are a growing technology for grid electricity consumers in low- and middle-income countries due to declining costs and government support. In Bangladesh, distributed photovoltaics iare part of broader solar and consumer programs. This study analyzes the economics of stylized grid-connected residential, commercial, and industrial distributed photovoltaics in Bangladesh, considering a year of hourly patterns of solar irradiation and electricity exchanges between the distributed photovoltaics owners and the electricity utilities. The economics vary between different stakeholders-distributed photovoltaics owners, electricity utilities, and society. From the consumers' perspective, the study finds that the economics of distributed photovoltaics depends on the difference in electricity production costs between the distributed photovoltaics and the electricity utility, transmission and distribution loss, and feed-in arrangements. The study also reveals that a distributed photovoltaics do not necessarily cause loss to the national electricity utility if they replaces expensive oil-fired generation. From a national or societal perspective, distributed photovoltaics are beneficial even if their positive environmental effects are not taken into account. The environmental benefits further improve the economics of distributed photovoltaics

    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

    Parallel Title: Erscheint auch als Timilsina, Govinda R The Nexus of Energy Supply and Human Health
    Abstract: Uses of main primary energy resources, such as coal, oil, and solid biomass, are directly linked with adverse impacts on human health. Air pollution emitted from various activities in the energy supply chains is the main risk factor to human health, along with accidental and occupational risk exposures. Estimates of premature deaths are over four million per year for ambient air pollution (2015) and household or indoor air pollution (2012). More than 80 percent of the mortality from ambient air pollution emitted from the energy supply chains occurs in developing countries. The impact of household air pollution, mainly from traditional biomass used for cooking and space heating, disproportionately falls on women and children under age five years. Acute respiratory infections, mainly caused by household air pollution, are one of the largest categories of deaths (64 percent) of children under age five years in developing countries. These statistics indicate the deep nexus between the energy supply chain and human health. Yet, the negative implications for human health from energy use often receive inadequate consideration. It is critically important to take account of these human health impacts in developing energy supply plans and energy policies in developing countries

    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: 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

    Parallel Title: Erscheint auch als Cao, Jing Impacts of Carbon Pricing in Reducing the Carbon Intensity of China's GDP
    Abstract: In contributing to global climate change mitigation efforts as agreed in Paris in 2015, China has set a target of reducing the carbon dioxide intensity of gross domestic product by 60-65 percent in 2030 compared with 2005 levels. Using a dynamic computable general equilibrium model of China, this study analyzes the economic and greenhouse gas impacts of meeting those targets through carbon pricing. The study finds that the trajectory of carbon prices to achieve the target depends on several factors, including how the carbon price changes over time and how carbon revenue is recycled to the economy. The study finds that carbon pricing that starts at a lower rate and gradually rises until it achieves the intensity target would be more efficient than a carbon price that remains constant over time. Using carbon revenue to cut existing distortionary taxes reduces the impact on the growth of gross domestic product relative to lump-sum redistribution. Recycling carbon revenue through subsidies to renewables and other low-carbon energy sources also can meet the targets, but the impact on the growth of gross domestic product is larger than with the other policies considered

    Abstract: This study develops an end-use energy demand analysis model for Romania to project energy demand by sector and end-use for 2015–50. The study finds that Romania's energy demand in 2050 would be 34 percent higher than the level in 2013. The industry sector would be the largest final energy-consuming sector, surpassing the residential sector from 2025 onward. The services sector would exhibit the fastest growth of energy consumption in line with the expected structural change from manufacturing to services. Although population in the country is projected to drop by 7 percent in 2050 from the 2013 level, electricity demand would increase by 46 percent over the same period, because of increased household income and the expanded service sector, which is relatively electricity intensive. Still, per capita electricity consumption in Romania will be about half the European Union 28 average. At the end-use level, thermal processes in the industry sector, space heating in the residential and services sectors, and road transportation in the transport sector would be dominant throughout the study period. The study also shows that improvement of energy efficiency in the heating system would be the main channel to cut energy demand in the country

    Abstract: Large-scale deployment of renewable energy technologies, such as wind power and solar energy, has been taking place in industrialized and developing economics mainly because of various fiscal and regulatory policies. An understanding of the economy-wide impacts of those policies is an important part of an overall analysis of them. Using a perfect foresight computable general equilibrium model, this study analyzes the economy-wide costs of achieving a 10 percent share of wind power in Brazil's electricity supply mix by 2030. Brazil is in the midst of an active program of wind capacity expansion. The welfare loss would be small, 0.1 percent of total baseline welfare in the absence of the 10 percent wind power expansion. The study also finds that, in the case of Brazil, production subsidies financed through increased value-added tax would have superior impacts on welfare and greenhouse gas mitigation, compared with a consumption mandate where electricity utilities are allowed to pass the increased electricity supply costs directly to consumers. These two policies would impact various production sectors differently to achieve the wind power expansion targets: the burden of the mandate falls mostly on electricity-intensive production and consumption, whereas the burden of the subsidy is distributed toward goods and services with higher value added

    Parallel Title: Hochman, Gal Why Has Energy Efficiency Not Scaled-up in the Industrial and Commercial Sectors in Ukraine?
    Abstract: Improvement of energy efficiency is one of the main options to reduce energy demand and to reduce greenhouse gas emissions in Ukraine. However, large-scale deployment of energy efficient technologies has been constrained by several financial, technical, information, behavioral, and institutional barriers. This study assesses these barriers through a survey of 500 industrial and commercial firms throughout Ukraine. The results from the survey were used in a cumulative multi-logit model to understand the importance of the barriers. The analysis shows that financial barriers caused by high upfront costs of energy efficient technologies, higher costs of finance, and higher opportunity costs of energy efficiency investment are key barriers to the adoption of energy efficiency measures in Ukraine. Institutional barriers particularly lack government policies, which also contributes to the slow adoption of energy efficient technologies in the country. The results suggest targeted policy and credit enhancements could help trigger adoption of energy efficient measures. The empirical analysis shows strong inter-linkages among the barriers and finds heterogeneity between industrial and commercial sectors on the realization of the barriers

    Parallel Title: Timilsina, Govinda R Economics of Transiting to Renewable Energy in Morocco
    Abstract: Morocco has set an ambitious target of supplying 42 percent of electricity through renewable sources, 14 percent each through hydro, wind, and solar, by 2020. To analyze the economic and environmental implications of implementing this target, this study uses a dynamic computable general equilibrium model with foresight that includes explicit representation of various electricity generation technologies. Two types of policy instruments, a production subsidy financed through fossil fuel taxation and a renewable energy mandate financed through increased electricity prices, have been considered to attract investment in renewable energy. The study shows that meeting the renewable target would achieve up to 15 percent reduction of national greenhouse gas emissions in 2020 compared with a situation in the absence of the target, or the baseline. However, meeting the target would decrease household consumption of goods and services, thereby worsening household welfare. The study also shows that the renewable production subsidy financed through fossil fuel taxation is superior to the mandate policy to meet the renewable energy target in Morocco, as the former would cause a lower loss in economic welfare and a larger reduction of greenhouse gas emissions than the latter

    Abstract: Transaction costs are major challenge to moving forward toward low-carbon economic growth, as new technologies or policies tend to have higher transaction costs compared with those in the business as usual situation. However, neither a well-developed theoretical foundation nor a consensus interpretation is available for those transaction costs in the existing literature. The definitions and therefore the estimations of transaction costs vary across existing studies. The wide variations in the estimates could be attributed to several factors such as the very definitions and scope of transaction costs considered in the studies, the methodology for quantifying these costs, the type and size of low-carbon technologies, and complexities involved in the transactions. Nevertheless, the existing literature converges on addressing market failures, such as lack of information, in developing regulatory and institutional capacity to enhance private sector confidence in energy efficiency business as a key means to help reduce the transaction costs of low-carbon technologies

    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

    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: 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: 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: 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

    Parallel Title: De Gorter, Harry The Effect of Biodiesel Policies on World Oilseed Markets and Developing Countries
    Abstract: Using an empirical model, this study provides some insights into the functioning of the oilseed-biodiesel-diesel market complex in a large country that determines the biodiesel price, reflecting market equilibrium changes resulting from volatility in the crude oil price. Oilseed crushing produces joint products-oil and meal-and this weakens the link between the biodiesel and oilseed feedstock prices. Higher crude oil prices increase biodiesel prices if biofuel benefits from a fuel tax exemption, but lower them with a blending mandate (minimum biofuel content requirement in marketed fuel). When both canola and soybeans are used to produce biodiesel, an increase in the crude oil price leads to higher canola prices, but the effect on soybean prices is ambiguous and depends on relative elasticities of meal demand and canola supply because canola produces more oil than soybeans. An oil price shock with a blending mandate results in a smaller change in oilseed prices compared with a fuel tax exemption. Jumps in world crude oil prices have differential impacts on commodity prices and welfare in developing countries, depending on which policy determines the biodiesel price in OECD countries

    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: Cororaton, Caesar B Impacts of Large-Scale Expansion of Biofuels on Global Poverty and Income Distribution
    Abstract: This paper analyzes the impact of large-scale expansion of biofuels on the global income distribution and poverty. A global computable general equilibrium model is used to simulate the effects of the expansion of biofuels on resource allocation, commodity prices, factor prices and household income. A second model based on world-wide household surveys uses these results to calculate the impacts on poverty and global income inequality. The study finds that the large-scale expansion of biofuels leads to an increase in production and prices of agricultural commodities. The increased prices would cause higher food prices, especially in developing countries. Moreover, wages of unskilled rural labor would also increase, which slows down the rural to urban migration in many developing countries. The study also shows that the effects on poverty vary across regions; it increases in South Asia and Sub-Saharan Africa, whereas it decreases in Latin America. At the global level, the expansion of biofuels increases poverty slightly

    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 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: Shiyan, Chang Development of Biofuels in China
    Abstract: China promulgated the Medium and Long-Term Development Plan for Renewable Energy in 2007, which included targets of 2010 and 2020 for various renewable energy technologies including biofuels. The 2010 biofuel targets were met and even surpassed except for non-grain fuel ethanol; however, there is debate on whether and how the country will be able to meet the 2020 biofuels target. This paper provides a resource and technological assessment of biofuel feedstocks, compares biofuel production costs from various feddstocks and technologies, and evaluates policies introduced in the country for the development of biofuels. The paper also presents the projections on the production of biofuels under various policy scenarios. The study shows that China can potentially satisfy its non-grain fuel ethanol target by 2020 from the technology perspective. But it will probably fall far short of this target without additional fiscal incentives as production costs of non-grain feedstock based biofuels are expected to remain relatively high. By contrast, the 2020 target of biodiesel production has a high probability of being achieved because the target itself is relatively small. With additional support policies, it could develop even further

    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: Ravallion, Martin Can We Trust Shoestring Evaluations?
    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

    Parallel Title: Y.-H. Henry Chen Economic Implications of Reducing Carbon Emissions from Energy use and Industrial Processes in Brazil
    Abstract: The overall impacts on the Brazilian economy of reducing CO2 emissions from energy use and industrial processes can be assessed using a recursive dynamic general equilibrium model and a hypothetical carbon tax. The study projects that in 2040 under a business-as-usual scenario, CO2 emissions from energy use and industrial processes would be almost three times as high as in 2010 and would account for more than half of total national CO2 emissions. Current policy aims to reduce deforestation by 70 percent by 2017 and emissions intensity of the overall economy by 36-39 percent by 2020. If policy is implemented as planned and continued to 2040, CO2 emissions from energy use and industrial processes would not have to be cut until 2035 as reductions of emissions through controlling deforestation would be enough to meet emission targets. The study also finds evidence that supports the double dividend hypothesis: using revenue from a hypothetical carbon tax to finance a cut in labor income tax significantly lowers the gross domestic product impacts of the carbon tax. Using carbon tax revenue to subsidize wind power can effectively increase the output of wind power in the country, although the impact of the tax on gross domestic product would be somewhat increased

    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: 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

    Parallel Title: Timilsina, Govinda R A Review of Solar Energy
    Abstract: Solar energy has experienced phenomenal growth in recent years due to both technological improvements resulting in cost reductions and government policies supportive of renewable energy development and utilization. This study analyzes the technical, economic and policy aspects of solar energy development and deployment. While the cost of solar energy has declined rapidly in the recent past, it still remains much higher than the cost of conventional energy technologies. Like other renewable energy technologies, solar energy benefits from fiscal and regulatory incentives and mandates, including tax credits and exemptions, feed-in-tariff, preferential interest rates, renewable portfolio standards and voluntary green power programs in many countries. Potential expansion of carbon credit markets also would provide additional incentives to solar energy deployment; however, the scale of incentives provided by the existing carbon market instruments, such as the Clean Development Mechanism of the Kyoto Protocol, is limited. Despite the huge technical potential, development and large-scale, market-driven deployment of solar energy technologies world-wide still has to overcome a number of technical and financial barriers. Unless these barriers are overcome, maintaining and increasing electricity supplies from solar energy will require continuation of potentially costly policy supports

    Parallel Title: Timilsina, Govinda R Biofuels and Climate Change Mitigation
    Abstract: The question of whether biofuels help mitigate climate change has attracted much debate in the literature. Using a global computable general equilibrium model that explicitly represents land-use change impacts due to the expansion of biofuels, this study attempts to shed some light on this question. The study shows that if biofuel mandates and targets currently announced by more than 40 countries around the world are implemented by 2020 using crop feedstocks, and if both forests and pasture lands are used to meet the new land demands for biofuel expansion, this would cause a net increase of greenhouse gas emissions released to the atmosphere until 2043, since the cumulative greenhouse gas emissions released through land-use change would exceed the reduction of emissions due to replacement of gasoline and diesel until then. However, if the use of forest lands is avoided by channeling only pasture lands to meet the demand for new lands, a net increase of cumulative greenhouse gas emissions would occur but would cease by 2021, only a year after the assumed full implementation of the mandates and targets. The study also shows, contrary to common perceptions, that the rate of deforestation does not increase with the rate of biofuel expansion; instead, the marginal rate of deforestation and corresponding land-use emissions decrease even if the production of biofuels increases

    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: 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

    Parallel Title: Timilsina, Govinda R Under What Conditions Does a Carbon Tax on Fossil Fuels Stimulate Biofuels?
    Abstract: A carbon tax is an efficient economic instrument to reduce emissions of carbon dioxide released from fossil fuel burning. Its impacts on production of renewable energy depend on how it is designed-particularly in the context of the penetration of biofuels into the energy supply mix for road transportation. Using a multi-sector, multi-country computable general equilibrium model, this study shows first that a carbon tax with the entire tax revenue recycled to households through a lump-sum transfer does not stimulate biofuel production significantly, even at relatively high tax rates. This reflects the high cost of carbon dioxide abatement through biofuels substitution, relative to other energy substitution alternatives; in addition, the carbon tax will have negative economy-wide consequences that reduce total demand for all fuels. A combined carbon tax and biofuel subsidy policy, where part of the carbon tax revenue is used to finance a biofuel subsidy, would significantly stimulate market penetration of biofuels. Although the carbon tax and biofuel subsidy policy would cause higher loss in global economic output compared with the carbon tax with lump sum revenue redistribution, the incremental output loss is relatively small

    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

    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: Timilsina, Govinda R World Oil Price and Biofuels
    Abstract: The price of oil could play a significant role in influencing the expansion of biofuels. However, this issue has not been fully investigated yet in the literature. Using a global computable general equilibrium model, this study analyzes the impact of oil price on biofuel expansion, and subsequently, on food supply. The study shows that a 65 percent increase in oil price in 2020 from the 2009 level would increase the global biofuel penetration to 5.4 percent in 2020 from 2.4 percent in 2009. A doubling of oil price in 2020 from its baseline level, or a 230 percent increase from the 2009 level, would increase the global biofuel penetration in 2020 to 12.6 percent. The penetration of biofuels is highly sensitive to the substitution possibility between biofuels and their fossil fuel counterparts. The study also shows that aggregate agricultural output drops due to an oil price increase, but the drop is small in major biofuel producing countries as the expansion of biofuels would partially offset the negative impacts of the oil price increase on agricultural outputs. An increase in oil price would reduce global food supply through direct impacts as well as through diversion of food commodities and cropland toward the production of biofuels

    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

    Abstract: This paper reviews recent developments in biofuel markets and their economic, social and environmental impacts. Several countries have introduced mandates and targets for biofuel expansion. Production, international trade and investment have increased sharply in the past few years. However, several existing studies have blamed biofuels as one of the key factors behind the 2007-2008 global food crisis, although the magnitudes of impacts in these studies vary widely depending on the underlying assumptions and structure of the models. Existing studies also have huge disparities in the magnitude of long-term impacts of biofuels on food prices and supply; studies that model only the agricultural sector show higher impacts, whereas studies that model the entire economy show relatively lower impacts. In terms of climate change mitigation impacts, there exists a consensus that current biofuels lead to greenhouse gas mitigation only when greenhouse gas emissions related to land-use change are not counted. If conversion of carbon rich forest land to crop land is not avoided, the resulting greenhouse gas release would mean that biofuels would not reduce cumulative greenhouse gas emissions until several years had passed. Overall, results from most of the existing literature do not favor diversion of food for large-scale production of biofuels, although regulated production of biofuels in countries with surplus land and a strong biofuel industry are not ruled out. Developments in second generation biofuels offer some hope, yet they still compete with food supply through land use and are currently constrained by a number of technical and economic barriers

    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

    Parallel Title: Timilsina, Govinda R The impacts of biofuel targets on land-use change and food supply
    Abstract: This study analyzes the long-term impacts of large-scale expansion of biofuels on land-use change, food supply and prices, and the overall economy in various countries or regions using a global computable general equilibrium model, augmented by a land-use module and detailed representation of biofuel sectors. The study finds that an expansion of global biofuel production to meet currently articulated or even higher national targets in various countries for biofuel use would reduce gross domestic product at the global level; however, the gross domestic product impacts are mixed across countries or regions. The expansion of biofuels would cause significant land re-allocation with notable decreases in forest and pasture lands in a few countries. The results also suggest that the expansion of biofuels would cause a reduction in food supply. Although the magnitude of the impact on food supply at the global level is not as large as perceived earlier, it would be significant in developing countries like India and those in Sub-Saharan Africa. Agricultural commodities such as sugar, corn, and oil seeds, which serve as the main biofuel feedstocks, would experience significant increases in their prices in 2020 compared with the prices at baseline due to the expansion of biofuels to meet the existing targets

    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

    Parallel Title: Wagstaff, Adam The World Bank's Publication Record
    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

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.

    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: Timilsina, Govinda R Second-generation biofuels
    Abstract: Recent increases in production of crop-based (or first-generation) biofuels have engendered increasing concerns over potential conflicts with food supplies and land protection, as well as disputes over greenhouse gas reductions. This has heightened a sense of urgency around the development of biofuels produced from non-food biomass (second-generation biofuels). This study reviews the economic potential and environmental implications of production of second-generation biofuels from a variety of various feedstocks. Although second-generation biofuels could significantly contribute to the future energy supply mix, cost is a major barrier to increasing commercial production in the near to medium term. Depending on various factors, the cost of second-generation (cellulosic) ethanol can be two to three times as high as the current price of gasoline on an energy equivalent basis. The cost of biodiesel produced from microalgae, a prospective feedstock, is many times higher than the current price of diesel. Policy instruments for increasing biofuels use, such as fiscal incentives, should be based on the relative merits of different types of biofuels

    Parallel Title: Timilsina, Govinda R Advanced biofuel technologies
    Abstract: Large-scale production of crop based (first generation) biofuels may not be feasible without adversely affecting global food supply or encroaching on other important land uses. Because alternatives to liquid fossil fuels are important to develop in order to address greenhouse gas mitigation and other energy policy objectives, the potential for increased use of advanced (non-crop, second generation) biofuel production technologies has significant policy relevance. This study reviews the current status of several advanced biofuel technologies. Technically, it would be possible to produce a large portion of transportation fuels using advanced biofuel technologies, specifically those that can be grown using a small portion of the world's land area (for example, microalgae), or those grown on arable lands without affecting food supply (for example, agricultural residues). However, serious technical barriers limit the near-term commercial application of advanced biofuels technologies. Key technical barriers include low conversion efficiency from biomass to fuel, limits on supply of key enzymes used in conversion, large energy requirements for operation, and dependence in many cases on commercially unproven technology. Despite a large future potential, large-scale expansion of advanced biofuels technologies is unlikely unless and until further research and development lead to lowering these barriers

    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: Timilsina, Govinda R Why Have CO2 Emissions Increased in the Transport Sector in Asia ?
    Abstract: Rapidly increasing emissions of carbon dioxide from the transport sector, particularly in urban areas, is a major challenge to sustainable development in developing countries. This study analyzes the factors responsible for transport sector CO2 emissions growth in selected developing Asian countries during 1980-2005. The analysis splits the annual emissions growth into components representing economic development; population growth; shifts in transportation modes; and changes in fuel mix, emission coefficients, and transportation energy intensity. The study also reviews existing government policies to limit CO2 emissions growth, particularly various fiscal and regulatory policy instruments. The study finds that of the six factors considered, three - economic development, population growth, and transportation energy intensity - are responsible for driving up transport sector CO2 emissions in Bangladesh, the Philippines, and Vietnam. In contrast, only economic development and population growth are responsible in the case of China, India, Indonesia, Republic of Korea, Malaysia, Pakistan, Sri Lanka, and Thailand. CO2 emissions exhibit a downward trend in Mongolia due to decreasing transportation energy intensity. The study also finds that some existing policy instruments help reduce transport sector CO2 emissions, although they were not necessarily targeted for this purpose when introduced

    Parallel Title: Anas, Alex Impacts of Policy Instruments To Reduce Congestion and Emissions From Urban Transportation
    Abstract: This study examines impacts on net social benefits or economic welfare of alternative policy instruments for reducing traffic congestion and atmospheric emissions in São Paulo, Brazil. The study shows that expanding road networks, subsidizing public transit, and improving automobile fuel economy may not be as effective as suggested by economic theories because these policies could cause significant rebound effects. Although pricing instruments such as congestion tolls and fuel taxes would certainly reduce congestion and emissions, the optimal level of these instruments would steeply increase the monetary cost of travel per trip and are therefore politically difficult to implement. However, a noticeable finding is that even smaller tolls, which are more likely to be politically acceptable, have substantial benefits in terms of reducing congestion and emissions. Among the various policy instruments examined in the study, the most socially preferable policy option for São Paulo would be to introduce a mix of congestion toll and fuel taxes on automobiles and use the revenues to improve public transit systems

    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: 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: Anas, Alex Lock-In Effects of Road Expansion On CO2 Emissions
    Abstract: In the urban planning literature, it is frequently explicitly asserted or strongly implied that ongoing urban sprawl and decentralization can lead to development patterns that are unsustainable in the long run. One manifestation of such an outcome is that if extensive road investments occur, urban sprawl and decentralization are advanced and locked-in, making subsequent investments in public transit less effective in reducing vehicle kilometers traveled by car, gasoline use and carbon dioxide emissions. Using a simple core-periphery model of Beijing, the authors numerically assess this effect. The analysis confirms that improving the transit travel time in Beijing’s core would reduce the city’s overall carbon dioxide emissions, whereas the opposite would be the case if peripheral road capacity were expanded. This effect is robust to perturbations in the model’s calibrated parameters. In particular, the effect persists for a wide range of assumptions about how location choice depends on travel time and a wide range of assumptions about other aspects of consumer preferences

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.

    Abstract: Using a nested multinomial logit model of car ownership and personal travel in Beijing circa 2005, this paper compares the effectiveness of different policy instruments to reduce traffic congestion and CO2 emissions. The study shows that a congestion toll is more efficient than a fuel tax in reducing traffic congestion, whereas a fuel tax is more effective as a policy instrument for reducing gasoline consumption and emissions. An improvement in car efficiency would also reduce congestion, fuel consumption, and CO2 emissions significantly; however, this policy benefits only richer households that own a car. Low-income households do better under the fuel tax policy than under the efficiency improvement and congestion toll policies. The congestion toll and fuel tax require the travel cost per mile to more than triple. The responsiveness of aggregate fuel and CO2 are, approximately, a 1 percent drop for each 10 percent rise in the money cost of a car trip

    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

    Abstract: This paper analyzes the economic and environmental consequences of a potential demand side management program in Thailand using a general equilibrium model. The program considers replacement of less efficient electrical appliances in the household sector with more efficient counterparts. The study further examines changes in the economic and environmental effects of the program if it is implemented under the clean development mechanism of the Kyoto Protocol, which provides carbon subsidies to the program. The study finds that the demand side management program would increase economic welfare if the ratio of unit cost of electricity savings to price of electricity is 0.4 or lower even in the absence of the clean development mechanism. If the program's ratio of unit cost of electricity savings to price of electricity is greater than 0.4, registration of the program under the clean development mechanism would be needed to achieve positive welfare impacts. The level of welfare impacts would, however, depend on the price of carbon credits the program generates. For a given level of welfare impacts, the registration of the demand side management program under the clean development mechanism would increase the volume of emission reductions

    Abstract: This paper reviews the literature on the fiscal policy instruments commonly used to reduce transport sector externalities. The findings show that congestion charges would reduce vehicle traffic by 9 to 12 percent and significantly improve environmental quality. The vehicle tax literature suggests that every 1 percent increase in vehicle taxes would reduce vehicle miles by 0.22 to 0.45 percent and CO2 emissions by 0.19 percent. The fuel tax is the most common fiscal policy instrument; however its primary objective is to raise government revenues rather than to reduce emissions and traffic congestion. Although subsidizing public transportation is a common practice, reducing emissions has not been the primary objective of such subsidies. Nevertheless, it is shown that transport sector emissions would be higher in the absence of both public transportation subsidies and fuel taxation. Subsidies are also the main policy tool for the promotion of clean fuels and vehicles. Although some studies are very critical of biofuel subsidies, the literature is mostly supportive of clean vehicle

    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

    Abstract: In 2005, China participated for the first time in the International Comparison Program (ICP), which collects primary data across countries on the prices for an internationally comparable list of goods and services. This paper examines the implications of the new Purchasing Power Parity (PPP) rate (derived by the ICP) for China's poverty rate (by international standards) and how it has changed over time. We provide estimates with and without adjustment for a likely sampling bias in the ICP data. Using an international poverty line of USD 1.25 at 2005 PPP, we find a substantially higher poverty rate for China than past estimates, with about 15% of the population living in consumption poverty, implying about 130 million more poor by this standard. The income poverty rate in 2005 is 10%, implying about 65 million more people living in poverty. However, the new ICP data suggest an even larger reduction in the number of poor since 1981

    Abstract: While the 2008 financial crisis is global in nature, it is likely to have heterogeneous welfare impacts within the developing world, with some countries, and some people, more vulnerable than others. It also threatens to have lasting impacts for some of those affected, notably through the nutrition and schooling of children in poor families. These features point to the need for a differentiated social policy response, aiming to provide rapid income support to those in most need, while preserving the key physical and human assets of poor people and their communities. The paper points out some mistakes in past crisis responses and identifies key design features for safety net programs that can help compensate for the likely welfare losses in the short-term while also promoting longer-term recovery

    Abstract: The theory and evidence supporting a relativist approach to poverty measurement are critically reviewed. Various sources of welfare interdependence are identified, including the idea of "relative deprivation" as well other (positive and negative) welfare effects for poor people of belonging to a better-off group. An economic model combines informal risk sharing with the idea of a "positional good," and conditions are derived in which the relative deprivation effect dominates, implying a relative poverty measure. The paper then reviews the problems encountered in testing for welfare effects of relative deprivation and discusses the implications of micro evidence from Malawi. The results are consistent with the emphasis given to absolute level of living in development policy discussions. However, relative deprivation is still evident in the data from this poor but unequal country, and it is likely to become a more important factor as the country develops

    Abstract: Drawing on a compilation of data from household surveys representing 130 countries, many over a period of 25 years, this paper reviews the evidence on levels and recent trends in global poverty and income inequality. It documents the negative correlations between both poverty and inequality indices, on the one hand, and mean income per capita on the other. It points to the dominant role of Asia in accounting for the bulk of the world's poverty reduction since 1981. The evolution of global inequality in the last decades is also described, with special emphasis on the different trends of inequality within and between countries. The statistical relationships between growth, inequality and poverty are discussed, as is the correlation between inequality and the growth elasticity of poverty reduction. Some of the recent literature on the drivers of distributional change in developing countries is also reviewed

    Abstract: Knowledge about development effectiveness is constrained by two factors. First, the project staff in governments and international agencies who decide how much to invest in research on specific interventions are often not well informed about the returns to rigorous evaluation and (even when they are) cannot be expected to take full account of the external benefits to others from new knowledge. This leads to under-investment in evaluative research. Second, while standard methods of impact evaluation are useful, they often leave many questions about development effectiveness unanswered. The paper proposes ten steps for making evaluations more relevant to the needs of practitioners. It is argued that more attention needs to be given to identifying policy-relevant questions (including the case for intervention); that a broader approach should be taken to the problems of internal validity; and that the problems of external validity (including scaling up) merit more attention

    Abstract: The paper presents the first major update of the international "USD 1 a day" poverty line, first proposed in 1990 for measuring absolute poverty by the standards of the world's poorest countries. In a new data set of national poverty lines we find that a marked economic gradient only emerges when consumption per person is above about USD 2.00 a day at 2005 purchasing power parity. Below this, the average poverty line is USD 1.25, which we propose as the new international poverty line. Relative poverty appears to matter more to developing countries than has been thought. Our proposed schedule of relative poverty lines is bounded below by USD 1.25, and rises at a gradient of USD 1 in USD 3 when mean consumption is above USD 2.00 a day

    Abstract: The authors provide new evidence on the extent to which absolute poverty has urbanized in the developing world, and the role that population urbanization has played in overall poverty reduction. They find that one-quarter of the world's consumption poor live in urban areas and that the proportion has been rising over time. By fostering economic growth, urbanization helped reduce absolute poverty in the aggregate but did little for urban poverty. Over 1993-2002, the count of the

    Abstract: The central governments of many developing countries have chosen to decentralize their anti-poverty programs, in the expectation that local agents are better informed about local needs. The paper shows that this potential advantage of decentralized eligibility criteria can come at a large cost, to the extent that the induced geographic inequities undermine performance in reaching the income- poor nationally. These issues are studied empirically for (probably) the largest transfer-based poverty program in the world, namely China's Di Bao program, which aims to assure a minimum income through means-tested transfers. Poor municipalities are found to adopt systematically lower eligibility thresholds, reducing the program's ability to reach poor areas, and generating considerable horizontal inequity

    Abstract: This paper shows how differences in aggregate human development outcomes over time and space can be additively decomposed into a pure economic-growth component, a component attributed to differences in the distribution of income, and components attributed to "non-income" factors and differences in the model linking outcomes to income or non-income characteristics. The income effect at the micro level is modeled non-parametrically, so as to flexibly reflect distributional changes. The paper illustrates the decomposition using data for Morocco and Vietnam, and the results offer some surprising insights into the observed aggregate gains in schooling attainments.

    Abstract: Policy-oriented discussions often assume that "better targeting" implies larger impacts on poverty or more cost-effective interventions. The literature on the economics of targeting warns against that assumption, but evidence has been scarce. The paper begins with a critical review of the strengths and weaknesses of the targeting measures found in practice. It then exploits an unusually large micro data set for China to estimate aggregate and local-level poverty impacts of the country's main urban antipoverty program. Standard measures of targeting are found to be uninformative, or even deceptive, about impacts on poverty and cost-effectiveness in reducing poverty. In program design and evaluation, it would be better to focus directly on the program's outcomes for poor people than to rely on prevailing measures of targeting

    Abstract: Brazil's slow pace of poverty reduction over the last two decades reflects both low growth and a low growth elasticity of poverty reduction. Using GDP data disaggregated by state and sector for a twenty-year period, this paper finds considerable variation in the poverty-reducing effectiveness of growth-across sectors, across space, and over time. Growth in the services sector was substantially more poverty-reducing than was growth in either agriculture or industry. Growth in industry had very different effects on poverty across different states and its impact varied with initial conditions related to human development and worker empowerment. The determinants of poverty reduction changed around 1994: positive growth rates and a greater (absolute) elasticity with respect to agricultural growth contributed to faster poverty reduction. But because there was so little of it, economic growth played a relatively small role in accounting for Brazil's poverty reduction between 1985 and 2004. The taming of hyperinflation (in 1994) and substantial expansions in social security and social assistance transfers, beginning in 1988, accounted for a larger share of the overall reduction in poverty

    Abstract: The authors report new estimates of measures of absolute poverty for the developing world over 1981-2004. A clear trend decline in the percentage of people who are absolutely poor is evident, although with uneven progress across regions. They find more mixed success in reducing the total number of poor. Indeed, the developing world outside China has seen little or no sustained progress in reducing the number of poor, with rising poverty counts in some regions, notably Sub-Saharan Africa. There are encouraging signs of progress in reducing the incidence of poverty in all regions after 2000, although it is too early to say if this is a new trend

    Abstract: This study analyzes CO2 emissions reduction targets for various countries and geopolitical regions by the year 2030 in order to stabilize atmospheric concentrations of CO2 at the level of 450 ppm (550 ppm including non CO2 greenhouse gases). It also determines CO2 intensity cuts that would be needed in those countries and regions if the emission reductions were achieved through intensity-based targets while assuming no effect on forecasted economic growth. Considering that the stabilization of CO2 concentrations at 450 ppm requires the global trend of CO2 emissions to reverse before 2030, this study develops two scenarios: reversing the global CO2 trend in (i) 2020 and (ii) 2025. The study shows that global CO2 emissions would be 42 percent above the 1990 level in 2030 if the increasing trend of global CO2 emissions is reversed by 2020. If reversing the trend is delayed by 5 years, the 2030 global CO2 emissions would be 52 percent higher than the 1990 level. The study also finds that to achieve these targets while maintaining assumed economic growth, the global average CO2 intensity would require a 68 percent drop from the 1990 level or a 60 percent drop from the 2004 level by 2030

    Abstract: This study examines the roles of revenue recycling schemes for the selection of alternative tax instruments (i.e., carbon-, sulphur-, energy- and output-tax) to reduce CO2 emissions to a specified level in Thailand. A static, single period, multi-sectoral computable general equilibrium (CGE) model of the Thai economy has been developed for this purpose. This study finds that the selection of a tax instrument to reduce CO2 emissions would be significantly influenced by the scheme to recycle the tax revenue to the economy. If the tax revenue is recycled to finance cuts in the existing labour or indirect tax rates, carbon tax would be more efficient than the sulphur-, energy- and output-taxes to reduce CO2 emissions. On the other hand, if the tax revenue is recycled to households through a lump-sum transfer, sulphur and carbon taxes would be more efficient than energy and output taxes. The ranking between the sulphur and carbon taxes under the lump sum transfer scheme depends on substitution possibility of fossil fuels. Sulphur tax is found superior over carbon tax at the higher substitution possibility between fossil fuels; the reverse is found true at the lower substitution possibility. In all schemes of revenue recycling considered, the output tax is found to be the most costly (i.e., in welfare terms) despite the fact that it generates two to three times higher revenue than the other tax instruments

    Abstract: The paper examines the ways in which recent economic growth has been uneven in China and India and what this has meant for inequality and poverty. Drawing on analyses based on existing household survey data and aggregate data from official sources, the authors show that growth has indeed been uneven-geographically, sectorally, and at the household level-and that this has meant uneven progress against poverty, less poverty reduction than might have been achieved had growth been more balanced, and an increase in income inequality. The paper then examines why growth was uneven and why this should be of concern. The discussion is structured around the idea that there are both "good" and "bad" inequalities-drivers and dimensions of inequality and uneven growth that are good or bad in terms of what they imply for both equity and long-term growth and development. The authors argue that the development paths of both China and India have been influenced by, and have generated, both types of inequalities and that while good inequalities-most notably those that reflect the role of economic incentives-have been critical to the growth experience thus far, there is a risk that bad inequalities-those that prevent individuals from connecting to markets and limit investment and accumulation of human capital and physical capital-may undermine the sustainability of growth in the coming years. The authors argue that policies are needed that preserve the good inequalities-continued incentives for innovation and investment-but reduce the scope for bad ones, notably through investments in human capital and rural infrastructure that help the poor connect to markets

    Abstract: The paper revisits the site of a large, World Bank-financed, rural development program in China 10 years after it began and four years after disbursements ended. The program emphasized community participation in multi-sectoral interventions (including farming, animal husbandry, infrastructure and social services). Data were collected on 2,000 households in project and nonproject areas, spanning 10 years. A double-difference estimator of the program's impact (on top of pre-existing governmental programs) reveals sizeable short-term income gains that were mostly saved. Only modest gains to mean consumption emerged in the longer term-in rough accord with the gain to permanent income. Certain types of households gained more than others. The educated poor were under-covered by the community-based selection process-greatly reducing overall impact. The main results are robust to corrections for various sources of selection bias, including village targeting and interference due to spillover effects generated by the response of local governments to the external aid

    Abstract: While the incidence of extreme poverty in China fell dramatically over 1980–2001, progress was uneven over time and across provinces. Rural areas accounted for the bulk of the gains to the poor, though migration to urban areas helped. The pattern of growth mattered. Rural economic growth was far more important to national poverty reduction than urban economic growth. Agriculture played a far more important role than the secondary or tertiary sources of GDP. Rising inequality within the rural sector greatly slowed poverty reduction. Provinces starting with relatively high inequality saw slower progress against poverty, due both to lower growth and a lower growth elasticity of poverty reduction. Taxation of farmers and inflation hurt the poor. External trade had little short-term impact. This paper—a product of the Poverty Team, Development Research Group—is part of a larger effort in the group to understand the causes of country success in poverty reduction

    Abstract: Chen and Ravallion use China's national household surveys for rural and urban areas to measure and explain the welfare impacts of the changes in goods and factor prices attributed to WTO accession. Price changes are estimated separately using a general equilibrium model to capture both direct and indirect effects of the initial tariff changes. The welfare impacts are first-order approximations based on a household model incorporating own-production activities and are calibrated to the household-level data imposing minimum aggregation. The authors find negligible impacts on inequality and poverty in the aggregate. However, diverse impacts emerge across household types and regions associated with heterogeneity in consumption behavior and income sources, with possible implications for compensatory policy responses. This paper—a product of the Poverty Team, Development Research Group—is part of a larger effort in the group to assess the household welfare impacts of economywide policy changes

    Abstract: While liberalizing key factor markets is a crucial step in the transition from a socialist control-economy to a market economy, the process can be stalled by imperfect information, high transaction costs, and covert resistance from entrenched interests. Ravallion and van de Walle study land-market adjustment in the wake of Vietnam's reforms aiming to establish a free market in land-use rights following de-collectivization. Inefficiencies in the initial administrative allocation are measured against an explicit counterfactual market solution. The authors' tests using a farm-household panel data set spanning the reforms suggest that land allocation responded positively but slowly to the inefficiencies of the administrative allocation. They find no sign that the transition favored the land rich or that it was thwarted by the continuing power over land held by local officials. This paper—a joint product of the Poverty Team and the Public Services Team, Development Research Group—is part of a larger effort in the group to understand the welfare impacts of major policy reforms

    Abstract: Does "empowerment" come hand-in-hand with higher economic welfare? In theory, higher income is likely to raise both power and welfare, but heterogeneity in other characteristics and household formation can either strengthen or weaken the relationship. Survey data on Russian adults indicate that higher individual and household incomes raise both self-rated power and welfare. The individual income effect is primarily direct, rather than through higher household income. There are diminishing returns to income, though income inequality emerges as only a minor factor reducing either aggregate power or welfare. At given income, the identified covariates have strikingly similar effects on power and welfare. There are some notable differences between men and women in perceived power. This paper—a product of the Poverty Team, Development Research Group—is part of a larger effort in the group to explore broader measures of well-being.

    Abstract: There has been much debate about how much India's poor have shared in the economic growth unleashed by economic reforms in the 1990s. Datt and Ravallion argue that India has probably maintained its 1980s rate of poverty reduction in the 1990s. However, there is considerable diversity in performance across states. This holds some important clues for understanding why economic growth has not done more for India's poor. India's economic growth in the 1990s has not been occurring in the states where it would have the most impact on poverty nationally. If not for the sectoral and geographic imbalance of growth, the national rate of growth would have generated a rate of poverty reduction that was double India's historical trend rate. States with relatively low levels of initial rural development and human capital development were not well-suited to reduce poverty in response to economic growth. The study's results are consistent with the view that achieving higher aggregate economic growth is only one element of an effective strategy for poverty reduction in India. The sectoral and geographic composition of growth is also important, as is the need to redress existing inequalities in human resource development and between rural and urban areas. This paper—a product of the Poverty Team, Development Research Group—is part of a larger effort in the department to better understand the relationship between economic growth and poverty.

    Abstract: April 1999 - As conventionally measured, current household income relative to a poverty line can only partially explain how Russian adults perceive their economic welfare. Other factors include past incomes, individual incomes, household consumption, current unemployment, risk of unemployment, health status, education, and relative income in the area of residence. Paradoxically, when economists analyze a policy's impact on welfare they typically assume that people are the best judges of their own welfare, yet resist directly asking them if they are better off. Early ideas of utility were explicitly subjective, but modern economists generally ignore people's expressed views about their own welfare. Even using a broad set of conventional socioeconomic data may not reflect well people's subjective perceptions of their poverty. Ravallion and Lokshin examine the determinants of subjective economic welfare in Russia, including its relationship to conventional objective indicators. For data on subjective perceptions, they use survey responses in which respondents rate their level of welfare from poor to rich on a nine-point ladder. As an objective indicator of economic welfare, they use the most common poverty indicator in Russia today, in which household incomes are deflated by household-specific poverty lines. They find that Russian adults with higher family income per equivalent adult are less likely to place themselves on the lowest rungs of the subjective ladder and more likely to put themselves on the upper rungs. But current household income does not explain well self-reported assessments of whether someone is poor or rich. Expanding the set of variables to include incomes at different dates, expenditures, educational attainment, health status, employment, and average income in the area of residence doubles explanatory power. Healthier and better educated adults with jobs perceive themselves to be better off, controlling for income. The unemployed view their welfare as lower, even with full income replacement. Individual income matters independent of per capita household income. Relative income also matters. Living in a richer area lowers perceived economic welfare, controlling for income and other factors. This paper-a product of Poverty and Human Resources, Development Research Group-is part of a larger effort in the group to better understand the relationship between objective and subjective economic welfare. The study was funded by the Bank's Research Support Budget under the research project Policies for Poor Areas (RPO 681-39).

    Abstract: July 1999 - A workfare program was introduced in response to high unemployment in Argentina. An ex-post evaluation using matching methods indicates that the program generated sizable net income gains to generally poor participants. Jalan and Ravallion use propensity-score matching methods to estimate the net income gains to families of workers participating in an Argentinian workfare program. The methods they propose are feasible for evaluating safety net interventions in settings in which many other methods are not feasible. The average gain is about half the gross wage. Even allowing for forgone income, the distribution of gains is decidedly pro-poor. More than half the beneficiaries are in the poorest decile nationally and 80 percent of them are in the poorest quintile - reflecting the self-targeting feature of the program design. Average gains for men and women are similar, but gains are higher for younger workers. Women's greater participation would not enhance average income gains, and the distribution of gains would worsen. Greater participation by the young would raise average gains but would also worsen the distribution. This paper - a product of Poverty and Human Resources, Development Research Group - is part of a larger effort in the group to improve methods for evaluating the poverty impact of Bank-supported programs.

    Abstract: March 2000 - In subjective surveys, people who become ill or lose their jobs report reduced well-being, even if they later get a job. Perhaps their exposure to uninsured risk outside the formal employment sector reduces their expectations about future income. Do potential biases cloud the inferences that can be drawn from subjective surveys? Ravallion and Lokshin argue that the welfare inferences drawn from subjective answers to questions on qualitative surveys are clouded by concerns about the structure of measurement errors and how latent psychological factors influence observed respondent characteristics. They propose a panel data model that allows more robust tests. In applying the model to high-quality panel data for Russia for 1994-96, they find that some results widely reported in past studies of subjective well-being appear to be robust but others do not. Household income, for example, is a highly significant predictor of self-rated economic welfare; per capita income is a weaker predictor. Ill health and loss of a job reduce self-reported economic welfare, but demographic effects are weak at a given current income. And the effect of unemployment is not robust. Returning to work does not restore a sense of welfare unless there is an income gain. The results imply that even transient unemployment brings the feeling of a permanent welfare loss, suggesting that high unemployment benefits do not attract people out of work but do discourage a return to work. This paper - a product of Poverty and Human Resources, Development Research Group - is part of a larger effort in the group to understand the relationship between subjective and objective economic welfare.

    Abstract: April 2000 - Community-level targeting of antipoverty programs is now common. Do local community organizations target the poor better than the central government? In one program in Bangladesh, the answer tends to be yes, but performance varies from village to village. The authors try to explain why. It is common for central governments to delegate authority over the targeting of welfare programs to local community organizations - which may be better informed about who is poor, though possibly less accountable for getting the money to the local poor - while the center retains control over how much goes to each local region. Galasso and Ravallion outline a theoretical model of the interconnected behavior of the various actors in such a setting. The model's information structure provides scope for econometric identification. Applying data for a specific program in Bangladesh, they find that overall targeting was mildly pro-poor, mostly because of successful targeting within villages. But this varied across villages. Although some village characteristics promoted better targeting, these were generally not the same characteristics that attracted resources from the center. Galasso and Ravallion observe that the center's desire for broad geographic coverage appears to have severely constrained the scope for pro-poor village targeting. However, poor villages tended not to be better at reaching their poor. They find some evidence that local institutions matter. The presence of cooperatives for farmers and the landless appears to be associated with more pro-poor program targeting. The presence of recreational clubs has the opposite effect. Sometimes the benefits of decentralized social programs are captured by local elites, depending on the type of spending being decentralized. When public spending is on a private (excludable) good, and there is no self-targeting mechanism to ensure that only the poor participate, there is ample scope for local mistargeting. This paper - a product of Poverty and Human Resources, Development Research Group - is part of a larger effort in the group to assess the performance of alternative means of reaching the poor through public programs. The study was funded by the Bank's Research Support Budget under the research project Policies for Poor Areas (RPO 681-39).

    Abstract: December 1999 - Nonfarm economic growth in India had very different effects on poverty in different states. Nonfarm growth was least effective at reducing poverty in states where initial conditions were poor in terms of rural development and human resources. Among initial conditions conducive to pro-poor growth, literacy plays a notably positive role. Ravallion and Datt use 20 household surveys for India's 15 major states, spanning 1960-94, to study how initial conditions and the sectoral composition of economic growth interact to influence how much economic growth reduced poverty. The elasticities of measured poverty to farm yields and development spending did not differ significantly across states. But the elasticities of poverty to (urban and rural) nonfarm output varied appreciably, and the differences were quantitatively important to the overall rate of poverty reduction. States with initially lower farm productivity, lower rural living standards relative to those in urban areas, and lower literacy experienced a less pro-poor growth process. This paper - a joint product of Poverty and Human Resources, Development Research Group, and the Poverty Reduction and Economic Management Sector Unit, South Asia Region - is part of a larger effort in the Bank to better understand the conditions required for pro-poor growth.
