Results in behavioral economics suggest that material incentives can crowd out motivation, if agents are mission-oriented rather than self-interested. We test this prediction on a sample of nonprofit organizations in Sweden. Swedish nonprofit organizations receive tax funds annually to promote...

Self-employed individuals have arguably greater opportunities than wage earners to underreport their incomes. This article uses recent Swedish income and expenditure data to examine the extent of underreporting of income among self-employed individuals. A key hypothesis is that underreporting of...

Recent research has reported positive effects on schooling due to in utero protection from iodine deficiency resulting from iodized oil capsule distribution in Tanzania. We revisit the Tanzanian experience by investigating how these effects differ over time and across surveys; across different...

Both practitioners and academics posit that microfinance organizations face a tradeoff between financial performance and outreach. We designed a randomized controlled trial of a transitory interest rate subsidy to investigate this tradeoff. We find that subsidized credit substantially increases...

We use time-series of rainfall to estimate the response of body weight to transitory changes in household income in rural Tanzania. We find that the response of body weight to income changes is positive on average, but that the impact is highest for female children, and lower for adults. For...
