Researchers partnered with the Senegalese government to evaluate the impact of a decentralized school grants program on student learning. The program improved test scores overall and for girls in younger grades. The impact was stronger in schools that invested more in human resource training rather than in school materials.

To evaluate potential methods of increasing voter participation, researchers examined the effect of a simple nonpartisan leaflet (e.g., a printed card) on voter turnout in the 1998 general election in the US city of Hamden, Connecticut. The card had no impact on turnout of voters registered with one of the two major political parties, but had a significant impact on turnout of unaffiliated voters.

Researchers used two randomized evaluations, an online survey and a field experiment, to test how personality traits affect responses to persuasive appeals to vote. They found that individuals with high levels of openness were most responsive to a range of appeals.
