By the widely used difference-in-difference method, the Southwest China Poverty Reduction Project had little impact on the proportion of people in beneficiary villages consuming less than $1 a day-despite a public outlay of $400 million. Is that right, or is the true impact being hidden somehow? The authors find that impact estimates are quite sensitive to the choice of outcome indicator, the poverty line, and the matching method. There are larger poverty impacts at lower poverty lines. And there are much larger impacts on incomes than consumptions. Uncertainty about the impact probably made it hard for participants to infer the gain in permanent income, so they saved a high proportion of the short-term gain.

By the widely used difference-in-difference method, the Southwest China Poverty Reduction Project had little impact on the proportion of people in beneficiary villages consuming less than $1 a day - despite a public outlay of $400 million. Is that right, or is the true impact being hidden somehow? Chen and Ravallion find that impact estimates are quite sensitive to the choice of outcome indicator, the poverty line, and the matching method. There are larger poverty impacts at lower poverty lines. And there are much larger impacts on incomes than consumptions. Uncertainty about the impact probably made it hard for participants to infer the gain in permanent income, so they saved a high proportion of the short-term gain. This paper - a product of the Poverty Team, Development Research Group - is part of a larger effort in the group to assess the impact on poverty of World Bank lending. The study was funded by the Bank's Research Support Budget under the research project Looking Beyond Averages: A Research Program on Poverty and Inequality (RPO 681-39).

"The author critically reviews the methods available for the ex-post counterfactual analysis of programs that are assigned exclusively to individuals, households, or locations. The discussion covers both experimental and non-experimental methods (including propensity-score matching, discontinuity designs, double and triple differences, and instrumental variables). Two main lessons emerge. First, despite the claims of advocates, no single method dominates; rigorous, policy-relevant evaluations should be open-minded about methodology. Second, future efforts to draw more useful lessons from evaluations will call for more policy-relevant measures and deeper explanations of measured impacts than are possible from the classic ("black box") assessment of mean impact.

Reviews the micro-level evidence on the effects of trade and investment liberalization in the developing world. He focuses, in particular, on the effects of the 1991 trade reform in India since it provides an excellent controlled experiment in which the effects of a drastic trade regime change can be measured. His main findings are: 1) There is evidence of trade-induced productivity gains (in this respect, however, India is an exception. 2) These gains mainly stem from intra-industry reallocation of resources among firms with different productivity levels. 3) The gains are larger in import-competing sectors. 4) There is no evidence of significant scale efficiency gains. Unilateral trade liberalization is often associated with a reduced scale efficiency. 5) There is evidence of a pro-competitive effect of trade liberalization. 6) There is no evidence either of learning-by-exporting effects or of beneficial spillover effects from foreign-owned to local firms active in the same sectors. 7) There is evidence, however, of positive vertical spillovers from foreign direct investment. 8) There is evidence of skill upgrading induced either by technology imports or by trade-induced reallocations of market shares in favor of plants with higher skill-intensity. 9) There is no evidence of trade-induced increases in labor demand elasticities. But direct evidence suggests that trade exposure raises wage volatility. 10) There is no evidence of substantial employment contraction in import-competing sectors.

Fernandes explores Colombian trade policy from 1977-91, a period of substantial variation in protection across industries, to examine whether increased exposure to foreign competition generates plant-level productivity gains. Using a large panel of manufacturing plants, she finds a strong positive impact of tariff liberalization on consistent productivity estimates, controlling for plant and industry heterogeneity. This result is not driven by the endogeneity of protection nor by plant exit. The impact of tariff liberalization on productivity is stronger for large plants and for plants in less competitive industries. Qualitatively similar results are obtained when using effective rates of protection and import penetration ratios as measures of protection. This paper--a product of Investment Climate, Development Research Group--is part of a larger effort in the group to understand the links between trade and productivity.

Even a modestly effective HIV-1 vaccine would be highly useful in India and could avoid millions of deaths. How should such a vaccine be introduced? Based on evidence of adoption of other vaccines in India, current levels of spending on them and coverage of prevention programs targeting both high- and low-risk groups, Seshadri, Subramaniyam, and Jha assess the potential demand for and strategic use of an HIV-1 vaccine in the four southern Indian states of Andhra Pradesh, Karnataka, Maharashtra, and Tamil Nadu. The authors also discuss potential strategies for delivery of the vaccine, prioritization for vaccination, and the political economy of such a vaccine in India. Assuming a vaccine cost of $10 a dose and including estimated delivery costs, the total cost of vaccinating 21.6 million adolescents 11-14 years of age and 1 percent of adults would be Rs. 12.25 billion (US$ 245 million). To maintain the vaccination rate in the 11-14 year old cohort, an additional 6.77 million in that age range would have to be vaccinated each year, at a vaccine cost of Rs. 3.39 billion (US$ 67.5 million). An HIV-1 vaccine will greatly reduce HIV/AIDS in India, but it will not be a panacea. There will be a continued need for effective prevention programs to guard against behavior reversals or an imperfect vaccine. Key inputs for prevention, immunization, and treatment programs such as identification of various groups that could be immunized (vulnerable groups or general populations), strengthened surveillance, capacity building, operations research, and evaluation at local levels will continue to require intensive support. This paper--a product of Public Services, Development Research Group--is part of the research project on The Economics of an HIV/AIDS Vaccine in Developing Countries: Potential Impact, Cost-Effectiveness, and Willingness to Pay," sponsored by the European Commission and the Development Research Group of the World Bank. The project was launched in response to recommendations of the World Bank's AIDS Vaccine Task Force.

This volume is intended to provide a comprehensive understanding of recent innovations related to the study of agricultural and environmental management for sustainable development. The book clearly identifies why the fight to achieve sustainable development in agricultural production must be fought along a broad multidisciplinary front to overcome issues such as soil erosion, poor water quality, pesticide contamination, and food insecurity. Readers are given a broad exposition of the trends and current practices of basic principles on sustainable agriculture, along with a detailed understanding of the use of sustainable agriculture to develop environmentally sustainable food production systems. The chapters describe the ecological sustainability of agricultural systems, current innovations to improve efficiency in the use of resources for sustainable agriculture, and the proposal for technological options and new areas of research in this very significant field of ​​agriculture. The authors aim to provide readers with a good subject understanding which will assist in the identification of agricultural development, environmental risk, sustainable resource management and design of appropriate responses. This book will be very helpful for students, researchers and practitioners interested in the fields of agriculture, environment and sustainable development.
