We hypothesize that the impact of antibiotics is moderated by a population's inherent (genetic) resistance to infectious disease. Using the introduction of sulfa drugs in 1937, we show that US states that are more genetically susceptible to infectious disease saw larger declines in their...

This paper examines the extent to which changes in working-age shares associated with population aging might slow economic growth in upcoming years. We first analyze the economic effects of changing working-age shares in a standard empirical growth model using country panel data from 1950-2015....

The world has experienced a dramatic decline in total fertility rate (TFR) since the Industrial Revolution. Yet the consequences of this decline flow not merely from a reduction in births, but from a reduction in the number of surviving children. We propose a new measure of the number of...

Extensive research has documented that elevated air pollution increases mortality and morbidity, with estimates reaching 8 million deaths per year. Many of the world's one billion urban poor face both high ambient concentrations and even higher transient peaks. Should government interventions...

Explanations for the West's escape from premature mortality have focused on chronic malnutrition or income and on public health or state capacity. We argue that by ignoring the multigenerational effects of variance in ancestors' harvests, we are underestimating the contribution of modern...

This study examines the long-term effects of prenatal exposure to war violence on cognitive and developmental outcomes, focusing on children in Afghanistan, a country deeply affected by prolonged violent conflict. Using data from the 2022 Afghanistan Multiple Indicator Cluster Surveys and...

The success of multi-faceted "graduation" programs at reducing poverty raises three questions: can the impacts of these programs be maintained when implemented by governments at scale, will positive effects be offset by negative spillovers, and can bundled programs be streamlined without losing...

Mental health disorders account for a significant share of the overall global disease burden. The economic losses from such disorders are staggeringly large, particularly in low-income countries, where people are faced with several unexpected shocks. We test whether improved communication can...

We study how reminding high-risk patients with chronic disease of their upcoming primary care appointments impacts their health care and behaviors. We leverage a natural experiment in Chile's public healthcare system that sent reminders before preventative care appointments to over 300,000...
