Researchers conducted a randomized evaluation to measure the impact of a school-based program that used a non-monetary penalty and regular monitoring to prevent adolescent tobacco use. The program reduced the probability that adolescents smoked, with effects sustained three months after the program ended. Incorporating a school competition component to the program had no further impact on smoking abstinence.

In Egypt, a sizable portion of the prison population is incarcerated solely for failing to repay private debts, highlighting serious concerns about the social, economic, and legal consequences of debtor imprisonment. Researchers are conducting two randomized evaluations, the first tests the impact of paying off the debts of incarcerated individuals on their post-release outcomes. The second study examines how the threat of imprisonment affects moral hazards and adverse selection in credit markets.
