Early life conditions can have profound effects on individual health, longevity, and biological fitness. Two classes of hypotheses are used to explain the evolutionary origins of these effects: developmental constraints (DC) hypotheses, which focus on the deleterious effects of low-quality...

In many regions of the world, sparse data on key economic outcomes inhibits the development, targeting, and evaluation of public policy. We demonstrate how advancements in satellite imagery and machine learning can help ameliorate these data and inference challenges. In the context of an...

The natural environment is central to all aspects of life, but efforts to quantify its influence have been hindered by data availability and measurement constraints. To mitigate some of these challenges, we introduce a new prototype of a microdata infrastructure: the Census Environmental Impacts...

In the late nineteenth century, the North American bison was brought to the brink of extinction in just over a decade. We demonstrate that the loss of the bison had immediate, negative consequences for the Native Americans who relied on them and ultimately resulted in a permanent reversal of...

The rigorous evaluation of anti-poverty programs is key to the fight against global poverty. Traditional approaches rely heavily on repeated in-person field surveys to measure program effects. However, this is costly, time-consuming, and often logistically challenging. Here we provide the first...

Time use data facilitate deeper understanding of individual labor supply choices, especially for women, who are more likely to engage in unpaid care and home production. However, traditional time use data collection methods are time-consuming, expensive and susceptible to significant attrition....

In the context of interwar Poland, we find that Jews tended to be more literate than non Jews, but show that this finding is driven by a composition effect. In particular, most Jews lived in cities and most non-Jews lived in rural areas, and people in cities were more educated than people in...

Health systems globally face increasing morbidity and mortality from chronic disease, yet many--especially in low- and middle-income countries--lack strong primary care. We analyze China's efforts to promote primary care management for insured rural Chinese with chronic disease, analyzing unique...

This paper examines the impact of California's hospital closures occurring from 1995-2011 on adjusted inpatient mortality for time-sensitive conditions: sepsis, stroke, asthma/chronic obstructive pulmonary disease (COPD) and acute myocardial infarction (AMI). Using a difference- in-difference...

In low-income countries, educators often encourage weak primary students to drop out before reaching the end of primary school in order to avoid the negative attention they receive when their students perform poorly on primary leaving exams. We conducted an experiment in rural Uganda that sought...
