This paper characterizes the equilibrium sets of an intrinsic common agency game with direct externalities between principals both under complete and asymetric information. Direct externalities arise when the contracting variable of one principal affects directly the other pricipal`s payoff....

In the context of common agency adverse-selection games we illustrate that the revelation principle cannot be applied to study equilibria of the multi-principal games. We then demonstrate that an extension of the taxation pricipal - what we term the "delegation priciple" - can be used to...

This paper characterizes the equilibrium sets of an intrinsic common agency game with discrete types and direct revelation mechanisms. After presenting a general algorithm to find the pure -strategy equilibria of this game, we use it to characterize these equilibria when the two principals...

We present a set of necessary and sufficient conditions for a class of optimal control problems with pure state constraints for which the objective function is linear in the state variable but the objective function is only required to be upper semicontinuous in the control variable. We apply...
