A randomized experiment among poor entrepreneurs tested the impact of exogenously inducing higher financial aspirations. In theory, raising aspirations could have positive effects by inducing higher effort, but could also reduce effort if unmet aspirations lead to frustration. Treatment resulted...

This paper tests how migrants' willingness to remit changes when given the ability to direct remittances to educational purposes using different forms of commitment. Variants of a dictator game in a lab-in-the-field experiment with Filipino migrants in Rome are used to examine remitting behavior...

Significant income gains from migrating from poorer to richer countries have motivated unilateral (source-country) policies facilitating labor emigration. However, their effectiveness is unknown. We conducted a large-scale randomized experiment in the Philippines testing the impact of...

Can temporary wartime mobilization change the long-run development trajectory of an economy? We study how mobilization for World War II in colonial India influenced its subsequent development. From 1939 to 1945, the British colonial government purchased massive amounts of war materiel within...

The Green Revolution bolstered agricultural yields and rural well-being in Asia and Latin America, but bypassed sub-Saharan Africa. We study the first randomized controlled trial of a government-implemented input subsidy program (ISP) in Africa. A temporary subsidy for Mozambican maize farmers...

Can informing people of high rates of community support for social distancing encourage them to do more of it? Our Mozambican study population underestimated the rate of community support for social distancing, believing support to be only 69%, while the true share was 98%. In theory, informing...

Using randomized methodologies, we study a common community HIV/AIDS program that seeks to promote HIV testing by improving knowledge and reducing stigmatizing attitudes. Contrary to expectations, the program has a substantial negative effect on HIV testing rates. We provide evidence of likely...

Societies worldwide spend substantial resources celebrating religious festivals. How do festivals influence economic and social outcomes? We study Catholic patron saint day festivals in Mexico, exploiting two features of the setting: (i) municipal festival dates vary across the calendar and were...

Interventions to promote learning are often categorized into supply- and demand-side approaches. In a randomized experiment to promote learning about COVID-19 among Mozambican adults, we study the interaction between a supply and a demand intervention, respectively: 1) teaching, and 2) providing...

How do information interventions affect individual efforts to expand social networks? We study a randomized controlled trial of a program providing information on settling in the U.S. for new immigrants from the Philippines. Improved information leads new immigrants to acquire fewer new social...
