Religious divisions have long played a primary role in major conflicts throughout much of the world. Intergroup contact may increase trust between members of different religions. However, evidence on how inter-religious contact affects individuals' behavior towards one another is scarce. We...

To boost college graduation rates, policymakers often advocate for academic supports such as coaching or mentoring. Proactive and intensive coaching interventions are effective, but are costly and difficult to scale. We evaluate a relatively lower-cost group coaching program targeted at...

In an effort to reduce the gender gap in the fields of science, technology, engineering and mathematics (STEM), policymakers often propose providing women with close mentoring by female scientists. This is based on the idea that female scientists might act as role models and counteract negative...

Despite the prevalence of school tracking, evidence on whether it improves student success is mixed. This paper studies how tracking within high school impacts high-achieving students' short- and longer-term academic outcomes. Our setting is a large and selective Chinese high school, where...

Women have historically been underrepresented in STEM majors and occupations, a gap that has persisted over time. There are concerns that this is related to academic choices made at an earlier age. The purpose of this paper is to examine how social environment affects women's STEM choices as...

An estimated 40 percent of the world's garbage is burned in open-air fires, which are responsible for as much as half of the global emissions of some pollutants. However, there is little evidence on the health consequences of open-air waste burning. In this paper, we estimate the effect of in...

Grouping students by ability is a controversial issue, and its impacts are likely to depend on the type of tracking students are exposed to. This paper studies a reform that moved French schools from a rigorous tracking system, which assigned students to tracks with significantly different...

Many countries offer new parents long periods of paid leave. Proponents argue that parental leave programs can reduce gender gaps in the labor market, support marital stability and promote children's well-being. In this paper, I show that lengthy leaves can instead work against several of these...

Most of the existing evidence on the effectiveness of family leave policies comes from studies focusing on their impacts on affected families – that is, mothers, fathers, and their children – without a clear understanding of the costs and effects on firms and coworkers. We use data from...

Labor market policies for expecting and new mothers emerged at the turn of the nineteenth century. The main motivation for these policies was to ensure the health of mothers and their newborn children. With increased female labor market participation, the focus has gradually shifted to the...
