We estimate effects of the largest U.S. federal grant for college students using administrative data from Texas four-year public colleges and a discontinuity in grant generosity. Eligibility for additional grant aid significantly increases degree receipt and earnings beginning four years after...

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...

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...

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...

Do new societal needs increase charitable giving or simply reallocate a fixed supply of donations? We study this question using IRS datasets and the natural experiment of deadly tornadoes. Among ZIP Codes located more than 20 miles away from a tornado's path, donations by households increase by...

We study the competition between public and religious schools and its consequences for nation building. In the 1970s, a landmark mass schooling effort in Indonesia aimed to secularize education and to curb religious influence in society. The regime built 61,000 public elementary schools, seeking...

We estimate the impact of student loan “nudges” on community college students' borrowing and provide the first experimental evidence of the effect of student loans on educational attainment. Nonbinding loan offers listed in students' financial aid award letters, that do not alter students'...

In a large-scale randomized experiment implemented with Kenya’s Electoral Commission in 2013, text messages intended to mobilize voters boosted electoral participation. However, the messages also decreased trust in electoral institutions after the election. This decrease was stronger for...
