We consider a model where multiple principals repeatedly offer short-term contracts to three or more agents with private information. Under low discounting there exists a simple class of mechanisms that sustains all equilibrium allocations that could be generated by arbitrarily complex...

This paper studies how implicit collusion may take place through simple non-exclusive contracting under adverse selection when multiple buyers (e.g., entrepreneurs with risky projects) non-exclusively contract with multiple firms (e.g., banks). It shows that any price schedule can be supported...

This paper provides a set of mechanisms that we refer to as emph{reciprocal mechanisms. }These mechanisms have the property that every outcome that can be supported as a Bayesian equilibrium in a competing mechanism game can be supported as an equilibrium in reciprocal mechanisms. In this sense,...

It is known that mechanism designers can extract agents' information about competitors' mechanisms in a competing mechanism game. This makes it possible for sellers to punish each other for deviations even when they do not directly observe other sellers' mechanisms. This allows for very...
