My main research field is empirical industrial organization, with a special emphasis on estimation of dynamic games and models of industry dynamics. One of my papers analyzes the exit process of movie theaters in the 1950's in the US, using a framework of dynamic game. I quantify the economic costs of consolidation that arise due to strategic interaction. Another paper proposes several statistical tests for the existence of multiple equilibria in dynamic Markov games.
I am also interested in developing methods of estimating treatment effects. One of my papers develops a method to estimate treatment effects in a situation where (1) there are multiple treatments, (2) the effect of a treatment depends on unobservable abilities of an individual, and (3) the effect varies depending on the time at which the individual is treated and the time elapsed since the treatment.
