A large literature has studied how peers affect behavior by exploiting the preexisting social network structure only. What if networks rewire in response to changes in the economic environment, such as a randomized intervention? We exploit a unique panel dataset that contains detailed...

This paper studies how formal financial access affects network-based financial arrangements. We use a field experiment that granted access to a savings account to a random subset of households in 19 Nepalese villages. Exploiting a unique panel dataset that follows all bilateral informal...

This study explores whether hospitals with higher increases in obesity levels have higher CS rates and the consequential effects on maternal and newborn health in Mexico for 2008-2015. It models how changes in the obesity level of hospitals' patient pools may affect the quantity and quality of...

The effect of negative shifts in public opinion on the economic lives of minorities is unknown. We study the role of racial bias in the U.S. labor market by investigating sudden changes in public opinion about Asians following the anti-Chinese rhetoric that emerged with the COVID-19 pandemic,...

We study the effect of the timing of SNAP payments on weekly labor supply using data from the CPS. We rely on exogenous variation in the fielding of CPS interviews relative to benefit receipt to estimate labor supply of SNAP eligible individuals at the end of their SNAP benefit cycle (i.e. about...

How do peers influence the impact of incentives? Despite much work on incentives, little is known about the spillover effects of incentives.

We study the impact of a mobile-app-based behavioral intervention on youth's financial literacy and financial behavior. To maximize the chances to reach out-of-school youth, we provided access to a user-friendly budget recording tool coupled with biweekly enumerators' visits and SMSs during a...

We study the role of social learning in the diffusion of cash crops in a resettled village economy in northeastern Brazil. We combine detailed geo-coded data on farming plots with dyadic data on social ties among settlers, and we leverage natural exogenous variation in network formation induced...

This paper provides the first direct evidence on the determinants of link formation among immigrants in the host society. We use a purposely-designed survey on a representative sample of Sri Lankan immigrants living in Milan to study how migrants form social links among them and the extent to...
