We examine the returns from owning cows and buffaloes in rural India. We estimate that when valuing labor at market wages, households earn large, negative average returns from holding cows and buffaloes, at negative 64% and negative 39% respectively. This puzzle is mostly explained if we value...

We show that the real return to capital in Ghana's informal sector is high. For farmers, we find annual returns ranging from 205-350% in the new technology of pineapple cultivation, and 30-50% in well-established food crop cultivation. We also examine the relative prices of durable goods of...

Lending to the poor is expensive due to high screening, monitoring, and enforcement costs. Group lending advocates believe lenders overcome this by harnessing social connections. Using data from FINCA-Peru, I exploit a quasi-random group formation process to find evidence of peers successfully...

Information asymmetries are important in theory but difficult to identify in practice. We estimate the empirical importance of adverse selection and moral hazard in a consumer credit market using a new field experiment methodology. We randomized 58,000 direct mail offers issued by a major South...

We designed a commitment savings product for a Philippine bank and implemented it using a randomized control methodology. The savings product was intended for individuals who want to commit now to restrict access to their savings, and who were sophisticated enough to engage in such a mechanism....

Questions remain as to whether results from experimental economics games are generalizable to real decisions in non-laboratory settings. Furthermore, important questions persist about whether social capital can help solve seemingly missing credit markets. I conduct two experiments, a Trust game...

Numerous laboratory studies report on behaviors inconsistent with rational economic models. How much do these inconsistencies matter in natural settings, when consumers make large, real decisions and have the opportunity to learn from experiences? We report on a field experiment designed to...
