We consider multiple-principal multiple-agent games of incomplete information. In this context, we identify a class of direct and incentive compatible mechanisms: each principal privately recommends to each agent to reveal her private information to the other principals, and each agent behaves...

We consider multiple-principal multiple-agent models of moral hazard: principals compete through mechanisms in the presence of agents who take unobservable actions. In this context, we provide a rationale for restricting principals to make use of simple mechanisms, which correspond to direct...

We consider multiple-principal multiple-agent games of incomplete information in which each agent can at most participate with one principal. In such contexts, we show that the restriction to direct truthful mechanisms involves a loss of generality, even if one only focuses on pure strategy...

This paper examines the role of direct mechanisms in common agency games. We focus on pure strategies and deterministic contracts and show how the introduction of a separability condition on the preferences of the agent is sufficient for the Revelation Principle to hold in in this setting, when...

This note presents a counter-example to Theorems 3 and 4 in Peters (2003, J. Eco. Theory) and suggests that indifference of the single agent with respect to principals' offers plays an important role in the failure of the Revelation Principle in Common Agency games. In addition we provide a new...
