We use the Becker-DeGroot-Marschak (BDM) mechanism to estimate willingness to pay
(WTP) for and heterogeneous impacts of clean water technology through a field experiment …

We synthesize two recent advances in the literature on instrumental variable (IV) estimation
that test and relax the exclusion restriction. Our approach first estimates the direct effect of …

The extent to which workers adjust to labor market disruptions in light of increasing pressure

The control function approach which employs an instrumental variable excluded from the
outcome equation is a very common solution to deal with the problem of endogeneity in …

This paper exploits the history of Reconstruction after the American Civil War to estimate the
causal effect of politician race on public finance. I overcome the endogeneity between …
