This paper provides conditions under which the inequality constraints generated by either single agent optimizing behavior or the best response condition of multiple agent problems can be used as a basis for estimation and inference. An application illustrates how the use of these inequality...

This paper provides conditions under which the inequality constraints generated by either single agent optimizing behavior, or by the Nash equilibria of multiple agent problems, can be used as a basis for estimation and inference. We also add to the econometric literature on inference in models...

Commercial health insurers in California use provider capitation payments to different extents. These are similar to arrangements introduced by the recent health reforms to give physicians incentives to control costs. In a previous paper we showed that patients whose insurers used capitation...
