We adopt the notion of von Neumann-Morgenstern farsightedly stable sets to predict with matchings are possibly stable when agents are farsighted in one-to-one matching problems. We provide the characterization of von Neumann-Morgenstern farsightedly stable sets : a set of matchings is a von...

We consider a two-country model of wage determination with private information in unionized imperfectly competitive industries. We investigate the effects of separated product markets opening up for competition as well as of further market integration on the negociated wage and the maximum delay...

What is the effect of product market integration on the market equilibrium in the presence of international externalities in consumption ? To address this question, we set up a spatial two-country model and we find that the economic forces at work may have an ambiguous effect on prices.

We develop a theoretical framework that allows us to study which bilateral links and coalition structures are going to emerge at equilibrium. We define the notion of coalitional network to represent a network and a coalition structure, whre the network specifies the natyure of the relationship...

We propose a new concept, the pairwise farsightedly stable set, in order to predict which networks may be formed among farsighted players. A set of networks G is pairwise farsightedly stable (i) if all possible pairwise deviations from any network g E G to a network outside G are deterred by the...

We study the endogenous formation of networks between manufacturers of differentiated goods and multi-product retailers who interact in a successive duopoly. Joint consent is needed to establish and/or maintain a costly link between a manufacturer and a retailer. We find that only three...

The paper examnes the formation of free trade agreements as a network formation game. We consider a three-country model in which international trade occurs between economies with imperfectly competitive product markets. Labor markets can be unionized and non-unionized in each country. We show...

We adopt the largest consistent set defined by Chwe (J. of Econ. Theory 63 (1994, 299-235) to predict which coalition structures are possibly stable when prayers are farsighted. We also introduce a refinement. the largest cautious consistent set, based on the assumption that players are...

In 2004, French health authorities plan to introduce a prospective payment system for hospitals delivering acute care based on the DRG classification system. In this paper, we analyze the consequences of this switch from a retrospective to a prospective payment system on the ability of...
