When there’s a successful agricultural extension program, how much of that success is sustained when it is discontinued? How long it takes to change behaviour, and whether change is permanent, can tell us a lot about whether the program is good value. Munshi Sulaiman tells Tim Phillips about a “reverse RCT” in Uganda that tested this question.

Managers often don’t know how much effort their workers are putting into a job. Technology offers a way to solve this problem by monitoring those workers automatically. But do all workers put in more effort when they are monitored? Golvine de Rochambeau talks to Tim Phillips about what happened when Liberia’s truck drivers had GPS trackers fitted to their trucks.

Are fathers more generous to their sons than their daughters?

In the 1960s, Brazil’s military dictatorship set out to undermine the power of local political elites by creating local political competition. New research finds that in the regions where the elites were strongest, the policies led to better governance, and more long-run growth. Claudio Ferraz and Monica Martinez-Bravo explain how this happened to Tim Phillips. Photo: Roberto Rocco TU Delft.

How does providing daycare affect infants, their parents, and even their grandparents during the seven years that follow? When Rio de Janeiro held a lottery for thousands of places, David Evans and Lycia Lima were two of a group of researchers who made the most of the opportunity to discover new evidence for the benefits of childcare, and they tell Tim Phillips what they found out.

If women want or need to work outside the home, someone needs to look after their kids. In Mexico, that person has traditionally been the grandmother. But what happens when she’s suddenly not around? Miguel Angel Talamas Marcos talks to Tim Phillips about his research that shows how important grandmothers are to female participation in the labour market.

When FDI mandates joint ventures foreign firms get market access, and their local partners get access to knowledge and technology in return. Does the policy benefit the host economy and its consumers more than other forms of FDI would have done? Jie Bai of Harvard Kennedy School talks to Tim Phillips.
