Overuse of medical care is often attributed to an informed expert problem, whereby doctors induce patients to purchase unnecessary treatments. Alternatively, patients may drive overuse of medications by exerting pressure on doctors to overprescribe, undermining the doctor's gatekeeping function...

Pre-Analysis Plans (PAPs) for randomized evaluations are becoming increasingly common in Economics, but their definition remains unclear and their practical applications therefore vary widely. Based on our collective experiences as researchers and editors, we articulate a set of principles for...

Although there is an extensive literature on the determinants of child labor and many initiatives aimed at combating it, there is limited evidence on the consequences of child labor on socio-economic outcomes such as education, wages, and health. We evaluate the causal effect of child labor...

This paper examines the relationship between household income shocks and child labor. In particular, we investigate the extent to which transitory income shocks lead to increases in child labor and whether household access to credit mitigates the effects of these shocks. Using panel data from a...

The returns to schooling and the skill premium are key parameters in various fields and policy debates, including the literatures on globalization and inequality, international migration, and technological change. This paper explores the skill premium and its correlation with exports in Latin...

This paper explores the links between exports, export destinations and skill utilization by firms. We identify two mechanisms behind these links, which we integrate into a unified theory of export destinations and skills. First, exporting to high-income countries with higher valuation for...
