Information asymmetries are prominent in theory but difficult to estimate. This paper exploits discontinuities in loan eligibility to test for moral hazard and adverse selection in the payday loan market. Regression discontinuity and regression kink approaches suggest that payday borrowers are...

This paper examines whether giving large cash transfers to financially distressed people causes them to avoid bankruptcy. A comparison of Florida Lottery winners who randomly received $50,000 to $150,000 to small winners indicates that such transfers only postpone bankruptcy rather than prevent...

A fundamental question faced by policymakers is how best to help individuals who are in financial trouble. This paper examines the consequences of the most basic approach: giving people large cash transfers. To determine whether this prevents or merely postpones bankruptcy, we exploit a unique...

Publicly funded exam schools educate many of the world's most talented students. These schools typically contain higher achieving peers, more rigorous instruction, and additional resources compared to regular public schools. This paper uses a sharp discontinuity in the admissions process at...

Nearly one million American youth have participated in service programs such as Peace Corps and Teach For America. This paper provides the first causal estimate of the impact of service programs on those who serve, using data from a web-based survey of former Teach For America applicants. We...

Charter schools were developed, in part, to serve as an R&D engine for traditional public schools, resulting in a wide variety of school strategies and outcomes. In this paper, we collect unparalleled data on the inner-workings of 35 charter schools and correlate these data with credible...

In this paper, we collect data on the inner-workings of 39 charter schools and correlate these data with school effectiveness. We find that traditionally collected input measures—class size, per-pupil expenditure, teacher certification, and teacher training—are not correlated with school...

Harlem Children's Zone (HCZ), which combines community investments with reform minded charter schools, is one of the most ambitious social experiments to alleviate poverty of our time. We provide the first empirical test of the causal impact of HCZ on educational outcomes, with an eye toward...
