Researchers tested whether making weekly calls to teachers, students, and the village chief during an adult education program in Niger could increase teacher accountability and improve student learning. Both the education program and the weekly calls increased students’ scores in reading and math.

In Mozambique, researchers evaluated if an information campaign using SMS, a hotline for electoral misconduct, and a free newspaper could affect voter turnout and other elections-related outcomes. All three programs increased voter turnout, while only distributing the newspaper strengthened demand for political accountability and reduced electoral problems.

Researchers tested the relative effectiveness and cost-effectiveness of an unconditional cash transfer and a voucher program on household consumption and well-being in a camp for internally displaced persons in the Democratic Republic of Congo. Both programs increased food security and asset ownership, but cash transfers were more cost-effective and allowed households to purchase a more diverse set of food and non-food items.

Researchers ran an evaluation in Niger to determine if training adults to use mobile phones could improve their learning outcomes when added to a standard adult education program. The mobile phone program increased student writing and math test scores relative to the standard curriculum.

In partnership with Concern Worldwide, researchers examined the relative effectiveness of traditional versus mobile cash transfers in Niger. Households who received electronic transfers had more diverse diets than those who received traditional cash transfers, in part due to time savings and shifts in women’s decision-making power within the household.

Researchers are evaluating the impact of an intensive nurse home visiting program for low-income mothers on pregnancy and birth outcomes, child health and development, and future life-courses for the family. The program had no effect on adverse birth outcomes or prenatal outcomes such as health care utilization; the other categories of outcomes are still being evaluated.

Researchers conducted a randomized evaluation with 9th graders’ parents in São Paulo to investigate whether weekly messages giving updates on a child’s attendance and effort, or messages emphasizing their importance, better motivated parents. Both types of messages led parents to ask more about school and encourage studying. Children’s attendance and learning also improved equally in both groups, showing that simple, importance-focused nudges can be just as effective and cheaper than updates on a specific child’s data.

Together with the provincial government, researchers evaluated the impact of a performance-based incentive scheme on tax inspectors’ performance in Punjab, Pakistan. The incentive scheme allowed tax inspectors to choose their next posting location based on their past performance; specifically, how each inspector performed, relative to others, determined the order in which inspectors would choose their next posting.

In Bogotá, Colombia, researchers partnered with the city to measure the impact of either concentrated policing, increased municipal clean-ups, or both on crime reduction and displacement. The evaluation found that the two approaches reduced crime on targeted streets when implemented together, but not when implemented alone. While most crime, particularly property crime, appears to have shifted to nearby streets, there is suggestive evidence that violent crimes, especially homicides and rapes, decreased citywide as a result of the intervention.
