This paper explores the foundations of religious influence in politics and society. We show that an important Islamic institution fostered the entrenchment of Islamism at a critical juncture in Indonesia, the world's largest Muslim country. In the early 1960s, rural elites transferred large...

What influences college student borrowing? In a field experiment with a large community college, we send emails about federal student loans to students who have received information about financial aid but have not made a borrowing decision. A treatment reminding students that they need not...

We estimate the effects of one of the largest anti-vote-buying campaigns ever studied -- with half a million voters exposed across 1427 villages--in Uganda's 2016 elections. Working with civil society organizations, we designed the study to estimate how voters and candidates responded to their...

We present the results from a field experiment on team diversity. Individuals working as door-to-door canvassers for a non-profit organization were randomly assigned a teammate, a supervisor, and a list of individuals to canvass. This created random variation within teams in the degree of...

Voter mobilization campaigns face trade-offs in young democracies. In a large-scale experiment implemented in 2013 with the Kenyan Electoral Commission (IEBC), text messages intended to mobilize voters boosted participation but also decreased trust in electoral institutions after the election, a...

We use regression discontinuity and regression kink designs to estimate the impact of need-based grant aid on the borrowing and educational attainment of students enrolled in a large public university system. Pell Grant aid substantially reduces borrowing: among students who would borrow in the...
