We show that contracting in agency with voluntary participation may involve incentives for the agent's abstention. Their provision alters the optimality criteria in the principal's decision-making, further distorts the mechanism, and may lead to breakdown of contracting in circumstances where...

Governments must usually take policy decisions with an imperfect knowledge of the economic actors' type or the actors' effort level. These issues are addressed within the framework of classic adverse selection or moral hazard models. I discuss in this paper how would the government’s and the...

This paper shows that the possibility of collusion between an agent and a supervisor imposes no restrictions on the set of implementable social choice functions (SCF) and associated payoff vectors. Any SCF and any payoff profile that are implementable if the supervisor's information was public...

This paper investigates the design of incentives in a dynamic adverse selection framework when agents’ production technologies display learning effects and agents’ rate of learning is private knowledge. In a simple two-period model with full commitment available to the principal, we show...

In the context of common agency adverse-selection games weillustrate that the revelation principle cannot be applied to studyequilibria of the multi-principal games. We then demonstrate thatan extension of the taxation principle what we term the delegation principle can be used to characterize...

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

I study the question of how much product information should be available to consumers. A monopolist sells one unit of product. The consumer is initially uninformed of the product value but can incur costs to observe a noisy signal of his valuation. I show that consumer surplus can be increasing...
