We present a model of online content sharing where agents sequentially observe an article
and decide whether to share it with others. This content may or may not contain …

Online behavioral data, such as digital traces from social media, have the potential to allow

Peer effects, in which an individual's behavior is affected by peers' behavior, are posited by
multiple theories in the social sciences. Randomized field experiments that identify peer …

Standard estimators of the global average treatment effect can be biased in the presence of
interference. This paper proposes regression adjustment estimators for removing bias due to …

This paper studies the design of two-wave experiments in the presence of spillover effects
when the researcher aims to conduct precise inference on treatment effects. We consider …

Abstract Payments for Environmental Services (PESs) are increasingly used to foster
farmers' adoption of greener practices, but their effectiveness is often undermined by low …

Identification and estimation of causal peer effects are challenging in observational studies
for two reasons. The first is the identification challenge due to unmeasured network …

We present current methods for estimating treatment effects and spillover effects under
“interference,” a term that covers a broad class of situations in which a unit's outcome …

This paper studies the design of cluster experiments to estimate the global treatment effect in
the presence of spillovers on a single network. We provide an econometric framework to …
