The researcher used a randomized evaluation in Papua New Guinea to study the impact of the Community Auxiliary Police (CAP), a program that devolves policing powers to carefully selected community members. Results suggest increased state presence may have widened the gap between men and women’s preferences for state versus customary authorities but did not reduce crime.

Researchers evaluated the impact of bank accounts that allowed mobile deposits on savings behavior in Sri Lanka. Few account holders used the service frequently, even when offered for free. Mobile-linked accounts increased savings deposits with the partner bank and formal banks more generally but had no impact on total savings.

Researchers partnered with the Indian NGO Pratham to evaluate whether different technologies and implementation methods can increase students’ English test scores. Overall, the interventions were effective at increasing students’ knowledge of English.

Researchers conducted a randomized evaluation to measure the demand for private tutoring services and estimate how pricing can influence enrollment in these services. Results suggest that higher prices reduced demand for private tutoring and also led to higher drop-out rates over time, with no impact of tutoring on test scores.

Researchers evaluated the impact of immediately following up an early childhood development intervention for one-to-three-year-old children with a second intervention for three-to-six-year-olds. The early and late interventions each increased IQ and school readiness for children, although there was not enough evidence to determine whether offering both programs was more effective than offering one.
