Efficient assignment with interdependent values

Efficient assignment with interdependent values

We study the “house allocation” problem in which n agents are assigned n objects, one for each agent, when the agents have interdependent values. We show that there exists no mechanism that is Pareto efficient and ex post incentive compatible, and the only mechanism that is group ex post incentive compatible is constant across states. By contrast, we demonstrate that a Pareto efficient and Baye...

Bargaining with Interdependent Values

A seller and a buyer bargain over the terms of trade for an object. The seller receives a perfect signal determining the value of the object to both players, while the buyer remains uninformed. We analyze the infinite horizon bargaining game in which the buyer makes all the offers. When the static incentive constraints permit first-best efficiency, then under some regularity conditions the outc...

Two-sided matching with interdependent values

We introduce and study two-sided matching with incomplete information and interdependent valuations on one side of the market. An example of such a setting is a matching market between colleges and students in which colleges receive partially informative signals about students. Stability in such markets depends on the amount of information about matchings available to colleges. When colleges ob...

Implementation with Interdependent Values∗ PRELIMINARY AND INCOMPLETE

Group stability in matching with interdependent values

We study two-sided many-to-one matching markets with interdependent valuations and imperfect information held by one side of the market. The other side has common and known preferences over potential mates. In this setting, pairwise stability does not imply group stability: mechanisms that are stable with respect to deviations by pairs of agents may be vulnerable to deviations by groups. We for...
