Evaluations

Improved crop varieties have the potential to produce higher yields than traditional varieties, but rural farmers often do not have the knowledge to properly grow these crops. Researchers seek to understand how providing different amounts of training on how to cultivate NERICA-3, a high-yield but...

Researchers conducted a randomized evaluation to test whether organizing short learning sessions for villagers about early adopters’ use of a flood-tolerant rice seed variety, Swarna-Sub1, impacted other farmers’ adoption of it. These “farmer field days” were a cost-effective strategy to improve...

Researchers evaluated the effect of randomly offering varied wages to bean-sorting workers in rural Malawi. While offering higher wages caused workers to increase their productivity, it did not attract more productive workers.

Researchers introduced a recruitment drive for a firm in Malawi to evaluate the impact of referral-based hiring on women’s employment at the company. Results from the randomized evaluation indicate that men systematically referred fewer women, and women’s referral of other qualified women was not...

Researchers will conduct a randomized evaluation to test the impact of different types of notifications on rates of failure to appear in traffic and criminal misdemeanor courts.

Researchers partnered with policymakers in New York City to evaluate the impacts of a redesigned court summons form and text message reminders on failure to appear (FTA) in court. A randomized evaluation found that text message reminders were able to reduce FTA by up to 26 percent, translating to 3...

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...

Researchers collaborated with Uber in Egypt to assess the impacts of expanding access to its ride services through price on the demand for ride-hailing and overall consumer mobility. Lowering the price of ride-hailing services increased people’s use of Uber and overall consumer mobility.
