This paper proposes a model of multilateral contracting where players are engaged in two parallel interactions: they dynamically form coalitions and play a repeated normal form game with temporary and permanent decisions. This formulation encompasses many economic models with externalities and...

There are more and more industries in which firms are specialized in the production of a component of the final good. This is especially true in high-tech industries. The basic question is why don't these firms merge ? We paradoxically show that industries which are typical candidates for...

Based on a result due to Ray and Vohra showing the possibility of inefficiency due to a coalition formation in an international emission reduction game, we consider a possibility of negotiation preceding the negotiation stage, and by means of an example, indicate that the efficiency is restored....

In this article we define and characterize a class of asymmetric leximin solutions, that contains both the symmetric leximin solution of Imai[5] and the two-person asymmetric Kalai-Smorodinsky solution of Dubra [3] as special cases. Solutions in this class combine three attractive features: they...

Existing theoretical literature fails to explain satisfactorily the differences between the pay of workers that are covered by collective agreements and others who are not. This study aims at providing a model framework which is amenable for an analysis of this issue. Our general-equilibrium...

It is given a brief overview over the experimental results in ultimatum games with complete and incomplete information, especially considering fairness. Following theories which model different fairness considerations are presented. The main part extends the Double Auction model by the inequity...

We examine the legislative game with open rules proposed by Baron and Ferejohn (1989). We first show that the three-group equilibrium suggested by Baron and Ferejohn does not always obtain. Second, we characterize the set of stationary equilibria for simple and super majority rules. Such...
