In 2008, Uganda granted hundreds of small groups $400/person to help members start individual skilled trades. Four years on, an experimental evaluation found grants raised earnings by 38% (Blattman, Fiala, Martinez 2014). We return after 9 years to find these start-up grants raised earnings and...

The economic consequences of COVID-19 lockdowns were significant for poor households in the Global South. In this crisis period, we investigate the very long-run impacts of a randomized cash grant in Uganda on three pre-specified outcomes, including a heterogeneity analysis by gender. In 2008,...

Improving youth labor market outcomes is a primary concern for countries around the world. We conduct a randomized controlled trial in Tanzania on an intense gender-sensitive skills training program that worked with over 53,000 youth in the region. After two years, we find the program increased...

Replication and constructive controversy are essential for scientific progress. This paper reviews the impact of all replications published as comments in the American Economic Review between 2010 and 2020. We investigate the citation rates of comments and whether a comment affects its original...

There is growing evidence that ethnic divisions and conflict experience affect social capital and economic interactions, in both positive and negative ways. However, recent work has suggested that the experience of electoral violence in Kenya does not correlate with laboratory behavior between...

Energy efficiency is a key component of climate policy. We study micro and macro rebound effects after the introduction of energy-efficient biomass cookstoves (EEBCs). We develop a model of biomass supply and demand in rural Africa. The impact of EEBCs is empirically explored in Rwanda where we...

The common practice in household questionnaires of surveying the most knowledgeable household member can lead to inaccurate data if they have limited information. Using survey experiments in Paraguay and Uganda, we investigate whether there are discrepancies in intra-household reporting on...

Reanalyses of empirical studies and replications in new contexts are important for scientific progress. Journals in economics increasingly require authors to provide data and code alongside published papers, but how much does the economics profession indeed replicate? This paper summarizes...

Using a novel dataset provided by the Connecticut Department of Health (CTDoH), this manuscript shows the necessity for and added utility from analyzing disaggregated COVID-19 outcome data for applied research. Connecticut is currently ranked the fourth highest state in death rates per 100,000...

Reducing the gender gap in education is a primary goal for many countries. Two major challenges for many girls are the distance to school and their safety when commuting to school. In Zambia, we studied the impact of providing a bicycle to a school-going girl who lives more than 3 km from the...
