Air Quality and Early-Life Mortality: Evidence from Indonesia's Wildfires

Smoke from massive wildfires blanketed Indonesia in late 1997. This paper examines the impact this air pollution (particulate matter) had on fetal, infant, and child mortality. Exploiting the sharp timing and spatial patterns of the pollution and inferring deaths from "missing children" in the 2000 Indonesian Census, I find that the pollution led to 15,600 missing children in Indonesia (1.2% of the affected birth cohorts). Prenatal exposure to pollution largely drives the result. The effect size is much larger in poorer areas, suggesting that differential effects of pollution contribute to the socioeconomic gradient in health.

Why the firstborn is more likely to succeed in life

Physical height is an important economic variable reflecting health and human capital. Puzzlingly, however, differences in average height across developing countries are not well explained by differences in wealth. We cannot close the malnutrition gap without addressing the social norms and economic rationales that deprive girls and younger siblings of the resources they nee

Life Expectancy and Human Capital Investments: Evidence From Maternal Mortality Declines

Longer life expectancy should encourage human capital accumulation, since a longer time horizon increases the value of investments that pay out over time. Previous work has been unable to determine the empirical importance of this life-expectancy effect due to the difficulty of isolating it from other effects of health on education. We examine a sudden drop in maternal mortality risk in Sri Lanka between 1946 and 1953, which creates a sharp increase in life expectancy for school-age girls without contemporaneous effects on health, and which also allows for the use of boys as a control group. Using additional geographic variation, we find that the 70% reduction in maternal mortality risk over the sample period increased female life expectancy at age 15 by 4.1%, female literacy by 2.5%, and female years of education by 4.0%.

The Price Effects of Cash Versus In-Kind Transfers

This paper compares how cash and in-kind transfers affect local prices. Both types of transfers increase the demand for normal goods, but only in-kind transfers also increase supply. Hence, in-kind transfers should lead to lower prices than cash transfers, which helps consumers at the expense of local producers. We test and confirm this prediction using a program in Mexico that randomly assigned villages to receive boxes of food (trucked into the village), equivalently-valued cash transfers, or no transfers. The pecuniary benefit to consumers of in-kind transfers, relative to cash transfers, equals 11% of the direct transfer.
