This paper provides evidence of the effects of a large-scale intervention that focuses on the quality of nutritional and child care inputs during the early stages of life. The empirical strategy uses a combination of double-difference and weighting estimators in a longitudinal survey to address the purposive placement of participating communities and estimate the effect of the availability of the program at the community level on nutritional outcomes. The authors find that the program helped 0-5 year old children in the participating communities to bridge the gap in weight for age z-scores and the incidence of underweight. The program also had significant effects in protecting long-term nutritional outcomes (height for age z-scores and incidence of stunting) against an underlying negative trend in the absence of the program. Importantly, the effect of the program exhibits substantial heterogeneity: gains in nutritional outcomes are larger for more educated mothers and for villages with better infrastructure. The program enables the analysis to isolate responsiveness to information provision and disentangle the effect of knowledge in the education effect on nutritional outcomes. The results are suggestive of important complementarities among child care, maternal education, and community infrastructure.

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).

This paper undertakes two calculations, one for all developing countries, the other for 34 developing countries that together account for 90 percent of the world's stunted children. The first calculation asks how much lower a country's per capita income is today as a result of some of its workers having been stunted in childhood. The analysis uses a development accounting framework, relying on micro-econometric estimates of the effects of childhood stunting on adult wages, through the effects on years of schooling, cognitive skills, and height, parsing out the relative contribution of each set of returns to avoid double counting. The estimates show that, on average, the per capita income penalty from stunting is around 7 percent. The second calculation estimates the economic value and the costs associated with scaling up a package of nutrition interventions using the same methodology and set of assumptions used in the first calculation. The analysis considers a package of 10 nutrition interventions for which data are available on the effects and costs. The estimated rate-of-return from gradually introducing this program over a period of 10 years in the 34 countries is 17 percent, and the corresponding benefit-cost ratio is 15:1.

One important concern of governments in developing countries is how to phase out large safety net programs. The authors evaluate the short-run effects of one possible exit strategy-programs that promote self-employment-in Argentina. They provide evidence that a small fraction of beneficiaries were attracted by this program. Overall, potential participants to self-employment are more likely to be female household heads and more educated beneficiaries relative to the average Jefes beneficiaries. Using nonexperimental methods, the authors show that participation in the program does affect the labor supply of participants, by reducing the probability of having an outside job, especially for males, and increasing the total number of hours worked. But the intervention fails to produce on average income gains to participating individuals and households in the short run. The fact that a small subset of former welfare beneficiaries are attracted to the program, coupled with the fact that only a subset of participants (younger and more educated beneficiaries, and with previous self-employment experience) benefited from participation has important implications for this intervention to represent a viable exit strategy from welfare.
