This paper compares the welfare effects of three ways in which health care can be organized: no competition (NC), competition for the market (CfM) and competition on the market (CoM) where the payer offers the optimal contract to providers in each case. We argue that each of these can be optimal...

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...

Many environmental-policy problems are characterized by complexity and uncertainty. Government's choice concerning these policies commonly relies on information provided by a bureaucracy. Environmental bureaucrats often have a political motivation of their own, so they might be tempted to...

Many mechanisms have been designed to solve the free-rider problem in public good environments. The designers of those mechanisms focused on good static equilibrium properties. In this paper, I propose a new mechanism for the provision of public goods that has good dynamic properties instead....

The Conditional Contribution Mechanism for public good provision gives all agents the possibility to condition their contribution on the total level of contribution provided by all agents. In this experimental study the mechanism's performance is compared to the performance of the Voluntary...

We study the bilateral trade problem put forward by Myerson and Satterthwaite (1983) under the assumption that agents are loss-averse. We use the model developed by Kőszegi and Rabin (2006, 2007) to find optimal mechanisms for the minimal subsidy, revenue maximization and welfare maximization...

We analyze the optimal design of dynamic mechanisms in the absence of transfers. The designer uses future allocation decisions to elicit private information. Values evolve according to a two-state Markov chain. We solve for the optimal allocation rule, which permits a simple implementation....

We introduce intention-based social preferences into a Bayesian mechanism design framework. We first show that, under common knowledge of social preferences, any tension between material efficiency, incentive compatibility, and voluntary participation can be resolved. Hence, famous impossibility...

A version of the herding prediction model with a rational expectations flavor is reexamined in the light of incentive theory. The welfare loss at the market solution with respect to the incentive efficient solution can be decomposed into an information externality term minus an incentive cost...

We analyze the problem of choosing the w contestants who will win a competition within a group of n w competitors when all jurors commonly observe who the w best contestants are, but they may be biased. We study conditions on the configuration of the jury so that it is possible to induce the...
