We study a Conditional Cash Transfer program in which the cash transfers to the mother only depend on the fulfillment of the national preventive visit schedule by her children born before she registered in the program. We estimate that preventive visits of children born after the mother...

The fetal origins hypothesis asserts that nutrient deprivation in utero can raise chronic disease risk. Within economics, this hypothesis has gained acceptance as a leading explanation for the correlations between birth weight, a proxy for fetal nutrient intake, and adult outcomes. Exploiting...

This paper studies the response of fertility to the HIV/AIDS epidemic in sub-Saharan Africa. I use repeated cross sections of the Demographic and Health Surveys for 12 countries in sub-Saharan Africa to examine this question empirically. Using individual birth histories from these data, I...

We evaluate the effect of smoking bans and excise taxes on the exposure to tobacco smoke of nonsmokers, and we show their unintended consequences on children. Smoking bans perversely increase nonsmokers' exposure by displacing smokers to private places where they contaminate nonsmokers. We...

In 1968, the Taiwanese government extended compulsory education from 6 to 9 years and opened over 150 new junior high schools at a differential rate among regions. Within each region, we exploit variations across cohorts in new junior high school openings to construct an instrument for...

This paper analyzes Thailand's 2001 healthcare reform, "30 Baht." The program increased funding available to hospitals to care for the poor and reduced copays to 30 Baht (~$0.75). Our estimates suggest the supply-side funding of the program increased healthcare utilization, especially among the...

We collect data on the rules and practices of financial and conflict disclosure by members of Parliament in 175 countries. Although two-thirds of the countries have some disclosure laws, less than one-third make disclosures available to the public, and less than one-sixth of potentially useful...

This study uses the malaria-eradication campaigns in the United States (circa 1920) and in Brazil, Colombia, and Mexico (circa 1955) to measure how much childhood exposure to malaria depresses labor productivity. The campaigns began because of advances in health technology, which mitigates...

We use a randomized experiment to test whether and what information changes teenagers' sexual behavior in Kenya. Providing information on the relative risk of HIV infection by partner's age led to a 28 percent decrease in teen pregnancy, an objective proxy for the incidence of unprotected sex....

We exploit the introduction of electronic toll collection, (E-ZPass), which greatly reduced both traffic congestion and vehicle emissions near highway toll plazas. We show that the introduction of E-ZPass reduced prematurity and low birth weight among mothers within 2 kilometers (km) of a toll...
