James Berry is an Assistant Professor in the Department of Economics at Cornell University. His research addresses questions in development and labor economics, primarily through the use of field experiments.

We utilize the Becker-Degroot-Marschak (1964) mechanism to estimate the willingness to pay for clean drinking water technology in northern Ghana. Under certain conditions, the BDM mechanism has attractive properties for empirical research, allowing us to directly estimate demand, compute heterogeneous treatment effects, and study the direct and screening effect of prices with minor modifications to a standard field experiment setting.
