Child welfare programs and child nutrition: Evidence from a mandated school meal program in India

Utilizing the data I collected on a nationally mandated school meal program in India, I examine the extent to which children benefit from the targeted public transfer. Relying upon built-in randomness in whether a child's 24-hour food consumption recall was for a school or non-school day, I find that the daily nutrient intake of program participants increased substantially by 49% to 100% of the transfers. The results are robust to the potential endogeneity of program placement and individual participation. The findings suggest that for as low a cost as 3 cents per child per school day the scheme reduced the daily protein deficiency of a primary school student by 100%, the calorie deficiency by almost 30% and the daily iron deficiency by nearly 10%. At least in the short-run, therefore, the program had a substantial effect on reducing hunger at school and protein-energy malnutrition.     

Poverty,undernutrition and vulnerability in rural India: role of rural public works and food for work programmes

This paper analyses the effects of access to Rural Public Works (RPW) or Food for Work programme (FFW) on consumption poverty, vulnerability and undernutrition in India using the large household data sets constructed by the National Sample Survey for 1993 and 2004. The treatment-effects model is used to take account of sample selection bias in evaluating the effects of RPW in 1993 or FFW in 2004 on poverty. We have found significant and negative effects of participation in RPW and the Food for Work Programme on poverty, undernutrition (e.g. protein) and vulnerability in 1993 and 2004.     

A proposal for social pricing of water supply in Côte d'Ivoire

We consider the design of a nonlinear social tariff for residential water in Côte d'Ivoire, which is a case of a monopolistic private operator supplying a population of heterogeneous consumers. The proposed optimal tariff includes an initial “social” block with a low unit price, and higher consumption blocks with a monopoly pricing rule. This optimal nonlinear tariff is calibrated using econometric estimates of a panel-data residential water demand equation. Welfare changes associated with moving from the actual tariff to approximations of the optimal pricing system are computed under different tariff scenarios. We find that gains in consumer welfare would outweigh losses in producer surplus in a majority of Ivorian local communities.     

Economic grounds for affirmative action: The evidence on architects and engineers in South Florida

Using data developed for, and presented to, the US District Court, this study evaluates the performance of women-, African-American-, and Hispanic-owned firms vis-à-vis firms owned by neither women nor minorities in three different South Florida markets: architecture, structural engineering, and civil engineering. After controlling for the influence of experience, size, and location, three of the most commonly used determinants of firms' earnings, the empirical results suggest that the three markets do not convert firms' characteristics into economic outcomes in the same manner for women and Hispanic owners as for owners who are neither women nor minorities.     

Growing richer and taller: Explaining change in the distribution of child nutritional status during Vietnam's economic boom

Over a five-year period in the 1990s Vietnam experienced annual economic growth of more than 8% and a 15 point decrease in the proportion of children chronically malnourished (stunted). We estimate the extent to which changes in the distribution of child nutritional status can be explained by changes in the level and distribution of income, and of other covariates. This is done using data from the 1993 and 1998 Vietnam Living Standards Surveys and a flexible decomposition technique based on quantile regression that explains change throughout the complete distribution of child height. One-half of the decrease in the proportion of children stunted is explained by changes in the distributions of covariates and 35% is explained by change in the distribution of income. Covariates, including income, explain less of the decrease in very severe malnutrition, which is largely attributable to change in the conditional distribution of child height.     

A healthier start: The effect of conditional cash transfers on neonatal and infant mortality in rural Mexico

Conditional cash transfer programs seek to break the intergenerational transmission of poverty by building the human capital of poor children. Despite their popularity throughout the developing world, relatively little is known about their effect on children's health outcomes. This paper evaluates the impact of the Mexican conditional cash transfer program, Progresa, on two important health outcomes: infant and neonatal mortality. It exploits the phasing-in of Progresa over time throughout rural Mexico to identify the impact of the program. The paper shows that Progresa led to a large 17% decline in rural infant mortality among the treated, but did not reduce neonatal mortality on average. The benefit-cost ratio is between 1.3 and 3.6. Tests for heterogeneity show larger declines for some groups including those municipalities whose pre-program levels of mortality were above the median, and those that prior to the program had higher illiteracy rates, and less access to electricity.     

Social Affiliation and the Demand for Health Services: Caste and Child Health in South India

This paper assesses the role of social affiliation, measured by caste, in shaping investments in child health. The special setting that we have chosen for the analysis - tea estates in the South Indian High Range - allows us to control nonparametrically for differences in income, access to health services, and patterns of morbidity across low caste and high caste households. In this controlled setting, low caste households spend more on their children's health than high caste households, reversing the pattern we would expect to find elsewhere in India. Moreover, health expenditures do not vary by gender within either caste group, in contrast once again with the male preference documented throughout the country. A simple explanation, based on differences in the returns to human capital across castes in the tea estates is proposed to explain these striking results.     

Women as agents of change: Female income and mobility in India

Economic globalization will give many women in developing countries access to steady and relatively remunerative employment for the first time, potentially shifting bargaining power within their households and changing the choices that are made for their children. This paper exploits a unique setting — a group of tea plantations in South India where women are employed in permanent wage labor and where incomes do not vary by caste — to anticipate the impact of globalization on mobility across social groups in the future. The main result of the paper is that a relative increase in female income weakens the family's ties to the ancestral community and the traditional economy, but these mobility enhancing effects are obtained for certain historically disadvantaged castes alone. Although the paper provides a context-specific explanation for why the women from these castes emerge as agents of change, the first general implication of the analysis is that the incentive and the ability of women to use their earnings to influence household decisions depends importantly on their social background. The second implication is that historically disadvantaged groups may, in fact, be especially responsive to new opportunities precisely because they have fewer ties to the traditional economy to hold them back.     

The social economic impact of AIDS: Accounting for intergenerational transmission,productivity and fertility

In this paper we develop a model that aims to investigate the economic and demographic impacts of three effects of the HIV-AIDS epidemic in developing countries. The direct effect of the HIV epidemic is that it increases mortality and morbidity. The two indirect effects, resulting from the first, are the reduction in productivity of adults and the transmission of the disease to their offsprings. We allow these different effects to act either separately or together, and we investigate the marginal efficiency of health expenditures on the survival probability of individuals and demographics. The direct effect of the HIV virus is that it leads adults to increase their own health expenditure and to decrease that of their children. On the contrary, the transmission effect of the HIV virus leads parents to spend more on their children than on their own. We show that the reduction in productivity of young adults decreases health expenditures for themselves and their children. Furthermore, we find that the productivity effect dominates by large the two others. Moreover, when adults decide to have fewer children because of HIV, we show that the ratio of low to high skilled workers increases. This demographic impact impoverishes the economy in the short and medium run.
