Obesity is increasing worldwide for both adults and children. Genetic disposition is responsible for some variation in body weight but cannot explain the dramatic increase in the last two decades. The increase must be due to structural and behavioral changes. One such behavioral change is the...

Health economists have studied the determinants of the expected value of health status as a function of medical and nonmedical inputs, often finding small marginal effects of the former. This paper argues that both types of input have an additional benefit, viz. a reduced variability of health...

In this paper, we address the issue of spurious correlation in the production of health in a systematic way. Spurious correlation entails the risk of linking health status to medical (and nonmedical) inputs when no links exist. This note first presents the bounds testing procedure as a method to...

This paper analyzes the identifying power of weak convexity assumptions in treatment effect models with endogenous selection. The counterfactual distributions are constrained either in terms of the response function, or conditional on the realized treatment, and sharp bounds on the potential...

There have been many studies of the volume-outcome relationship. In all of these, the unit of analysis is the hospital or physician. However, this level of analysis is mostly limited to the use of in-hospital mortality rates and is particularly sensitive to selective referral. Moreover, the...

This paper uses year-to-year variation in temperature to estimate the long-term effects of climate change on health outcomes in Mexico. Combining temperature data at the district level and three rounds of nationally representative household surveys, an individual’s health as an adult is...

This paper attempts to identify the climatic effect on birth outcomes in Brazil and, thus, to predict the potential impact of climate change. Panel data models indicate that excess and lack of rainfall have the most important harmful effects on newborns' health; temperature stresses and low...

This paper uses microdata from Brazilian natality and mortality vital statistics between 2000 and 2010 to estimate the impact of in-utero exposure to local violence - measured by homicide rates - on birth outcomes. The estimates show that exposure to violence during the first trimester of...

This study explores the impact of air pollution on adverse birth outcomes. The study focuses on the effect of breathable particulate matter with diameter of 10 micrometers or less (PM10) on the likelihood of premature birth and low birth weight (LBW). The study exploits the fact that in 2011 the...

In-service teacher training aims to improve the supply of public education. A randomized experiment was conducted in Mexico to test whether teacher training could increase teacher efficiency in public secondary schools. After seven and a half months of exposure to a trained teacher, students...
