We implemented a randomized intervention among Malawian farmers aimed at facilitating formal savings for agricultural inputs. Treated farmers were offered the opportunity to have their cash crop harvest proceeds deposited directly into new bank accounts in their own names, while farmers in the...

We report the results of a randomized field experiment that examines the credit market impacts of improvements in a lender's ability to determine borrowers' identities. Improved personal identification enhances the credibility of a lender's dynamic repayment incentives by allowing it to withhold...

The very poor in developing countries often make intertemporal choices that seem at odds with their individual self-interest. There are many possible reasons why. We investigate several of these reasons with a lab-in-the-field experiment in rural Malawi involving large stakes. We make two...

We develop a simple theory which formally describes how charities can resolve the information asymmetry problems faced by small donors by working with large donors to generate quality signals. To test the model, we conducted two large-scale natural field experiments. In the first experiment, a...

We worked with two microlenders to test impacts of randomly assigned reminders for loan repayments in the "text messaging capital of the world". We do not find strong evidence that loss versus gain framing or messaging timing matter. Messages only robustly improve repayment when they include the...

We document the presence of multiple and varied constraints to small and medium firm growth. This presents both a practical problem for business training programs and a challenge to academic economists trying to identify mechanisms though which these programs may affect outcomes. External...

We evaluate, using a randomized trial, two school-based financial literacy education programs in government-run primary and junior high schools in Ghana. One program integrated financial and social education, whereas the second program only offered financial education. Both programs included a...

Commitment devices offer an opportunity to restrict future choices. However, if severe restrictions deter participation, weaker restrictions may be a more effective means of changing behavior. We test this using a school-based commitment savings device for educational expenses in Uganda. We...

Evidence on the effectiveness of financial education and formal savings account access is lacking, particularly for youth. We randomly assign 250 youth clubs to receive either financial education, access to a cheap group account, or both. The financial education treatments increase financial...

Theory and evidence have raised concerns that microcredit does more harm than good, particularly when offered at high interest rates. We use a clustered randomized trial, and household surveys of eligible borrowers and their businesses, to estimate impacts from an expansion of group lending at...
