We study a cost allocation problem under asymmetric information, and show that the ex ante incentive compatible core is non-empty. We also obtain a non-emptiness result for the incentive compatible coarse core, which is one concept of an interim core.

In this paper we show that in quasilinear economies the incentive compatible coarse core is non-empty if agents are informationally small in the sense of McLean and Postlewaite (2002) and the strict core in each state is non-empty.

The Nash program is an important research agenda initiated in Nash (1953) in order to bridge the gap between the noncooperative and cooperative branches of game theory. Many results can be found in it, and the reader is referred to Serrano (2005, 2008) for two complementary surveys. With this...

This is a brief survey describing some of the recent progress and open problems in the area of cooperative games with incomplete information. We discuss exchange economies, cooperative Bayesian games with orthogonal coalitions, and issues of cooperation in noncooperative Bayesian games.

Consider any investor who fears ruin when facing any set of investments that satisfy no-arbitrage. Before investing, he can purchase information about the state of nature in the form of an information structure. Given his prior, information structure $\alpha$ is more informative than information...

The authors study a multilateral bargaining procedure that extends A. Rubinstein's (1982) alternating offer game to the case of n players. The procedure captures the notion of consistency in the sense familiar in cooperative game theory and they use it to establish links to the axiomatic theory...

We analyse a market where (i) trade proceeds by random and anonymous pairwise meetings with bargaining; (ii) agents are asymmetrically informed about the value of the traded good; and (iii) no new entrants are allowed once the market is open. We show that information revelation and efficiency are...
