We study communication in a static Cournot duopoly model under the assumption that the firms have unverifiable private information about their costs. We show that cheap talk between the firms cannot transmit any information. However, if the firms can communicate through a third party,...

This paper studies a 2-agent, 2-type principal-multiagent model of adverse selection under the assumption that the agents each have complete information. We construct a mechanism implementing the first-best contracts in Nash equilibrium that: satisfies a condition related to individual...

It is well known that non-renegotiable contracts with third parties may have an effect on the outcome of a strategic interaction and thus serve as a commitment device. We address this issue when contracts are renegotiable. More precisely, we analyze the equilibrium outcomes of two-stage games...

We introduce a model of product development in a firm. Our model describes the process as a multi-stage contest (i.e., race) with an endogenous length (with one stage or two stages) between two workers. We model the payments to workers from the new product using the normatively appealing Nash...

This paper analyzes the effects of forward contracts and managerial incentive contracts, which are tools that firms can use to compete strategically with their rivals in an oligopolistic market. The results show that when the two firms produce a homogeneous good, can hire managers and trade...

I formalise a rather stylised insurance market with adverse selection as a standard duopoly. I formally specify demand functions and profits and I prove that a Nash equilibrium in pure strategies exists if and only if the well-known Rothschild-Stiglitz allocation is efficient

Games with imperfect information often feature multiple equilibria, which depend on beliefs off the equilibrium path. Standard selection criteria such as passive beliefs, symmetric beliefs or wary beliefs rest on ad hoc restrictions on beliefs. We propose a new selection criterion that imposes...

In general screening problems, implementable allocation rules correspond exactly to Walrasian equilibria of an economy in which types are consumers with quasilinear utility and unit demand. Due to the welfare theorems, an allocation rule is implementable if and only if it induces an efficient...
