In partnership with Bridges to Prosperity, the researchers are conducting a randomized evaluation across 23 districts in Rwanda to determine the impact of building footbridges on wages and agricultural technology adoption and production.

Researchers evaluated the impact of an early childhood psychosocial stimulation program on child development outcomes in urban Odisha, India. They found that a home-visiting stimulation program led to greater development outcomes, particularly for boys, stunted children, and children with more educated mothers.

In Hong Kong, researchers conducted a randomized evaluation to test the impact of indirectly incentivizing protest participation on sustained participation in a political movement and to identify the role social networks play in protest turnout. Indirectly incentivizing participants to attend a political protest increased their participation regardless of how many of their peers received the same incentive. Participants’ subsequent protest participation remained persistently higher a year later, but only when at least half of their social network was also incentivized to attend the initial protest.

In Liberia and Malawi, researchers partnered with Innovations for Poverty Action, GiveDirectly, and USAID to evaluate the impact of an unconditional cash transfer and market access program on food security, spending, income, resilience to health shocks, intimate partner violence, and psychological well-being. In both countries, households that received cash transfers experienced lasting increases in food security, psychological well-being, and resilience to health shocks.

Researchers conducted two randomized evaluations in Bangladesh to study the impact of a new irrigation method and different pricing schemes on water use and conservation. The new irrigation method reduced water consumption and costs for farmers who were already paying for water by the hour, or by volume.

In partnership with the Latvian tax authority, researchers tested several types of emails to investigate the effect of behaviorally-informed messages on tax compliance. Messages that aimed to deter bad behavior by highlighting taxpayers’ moral obligations towards action increased on-time tax declaration submissions. In contrast, messages meant to induce social pressure did not increase on-time compliance, though they increased overall submission rates (i.e., the submission of on-time as well as late declarations).

Researchers partnered with the Government of Indonesia to conduct a randomized evaluation that tested whether adding questions on flat-screen televisions and cellphone SIM cards to a targeting census would change people’s reporting and actual purchases of those items. The findings suggest that while targeting may cause people to misreport what they own in the short term for some goods, it is unlikely to change people’s decisions about whether to actually purchase those items.

Primary school teachers in Uganda face public scrutiny and high pressure around primary school exit exam results. As a result of the incentives around students being successful on this exam, teachers focus their energy on students who could receive passing marks and encourage lower-performing students to drop out prior to taking the exam. Researchers evaluated whether an alternative teacher incentive scheme, providing rewards based on the performance of all students, could help reduce dropout and improve student math learning. Introducing the pay-for-percentile incentive scheme reduced overall student dropout rates. However, these reductions were driven almost entirely by students at intervention schools with math textbooks. Among schools with math books, the incentive scheme also improved the math achievement for higher performing students.

In Niger, researchers evaluated the impact of a training program for input distributors (agro-dealers) on smallholder access to and use of agricultural inputs. Researchers found that trainings for agro-dealers combined with a demonstration plot increased the share of farmers adopting improved seeds, but did not increase the quantity used to have an impact on agricultural output.

Researchers are measuring the impact of a quiz-style information strategy on people’s learning and adherence to Covid-19 health protocols. This study is part of a three-country research program in Ghana, the US, and Zambia aiming to find evidence on the best strategies to communicate health measures.
