Networks may rewire in response to interventions. We propose a measure of the total treatment effect for those situations where an intervention may affect the network structure. To build this measure, we develop a treatment response model allowing for dynamic peer effects. We illustrate our...

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...

We study how 3,534 beneficiaries of PROSPERA, Mexico's cash transfer program, smooth food consumption around the transfer payday, an anticipated and transitory income shock. We find that food consumption and food security do not change around the transfer payday, including for recipients with...

How do peers influence the impact of incentives? Despite much work on incentives, little is known about the spillover effects of incentives. We investigate two mechanisms by which these effects can occur: through peers' actions and peers' incentives. In a field experiment on snack choice (grapes...

The rise of childhood obesity in less developed countries is often overlooked. We study the impact of body weight report cards in Mexico. The report cards increased parental knowledge and shifted parental attitudes about children's weight. We observe no meaningful changes in parental behaviors...

Digital loans are a source of fast, short-term credit for millions of people. While digital credit broadens market access and reduces frictions, default rates are high. We study the role of the speed of delivery of digital loans on repayment. Our study uses unique administrative data from a...

We test the ability of SNAP eligible households to smooth consumption when facing unexpected transitory income shocks stemming from the 2018-19 government shutdown. In response to the shutdown, all states were federally mandated to pay February SNAP benefits on or before January 20th. This...
