We show that a number of “noncognitive” skills and preferences, including patience and identity, are malleable in adults, and that investments in them reduce crime and violence. We recruited criminally-engaged men and randomized half to eight weeks of cognitive behavioral therapy designed to...

Employment growth could reduce violence during civil conflicts. To determine if increased employment affects violence we analyzed varying employment in development programs run by different US military divisions in Iraqi districts. Employment levels vary with funding periods and the military...

Prevention of mother-to-child transmission of HIV (PMTCT) is the single most effective HIV prevention intervention in practice today. Nonetheless, little reliable empirical evidence exists on the behavioral effects of PMTCT. This paper documents the rapid expansion of access to PMTCT in Zambia...

Eleven percent of the Malawian population is HIV infected. Eighteen percent of sexual encounters are casual. A condom is used one quarter of the time. A choice-theoretic general equilibrium search model is constructed to analyze the Malawian epidemic. In the developed framework, people select...
