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...

We introduce a class of games with complementarities that has the quasisupermodular games, hence the supermodular games, as a special case. Our games retain the main property of quasisupermodular games : the Nash set is a nonemply complete lattice. We use monotonicity properties on the best...

We reconsider Goyal and Moraga-Gonzalez (Rand J. of Econ. 32 (2001), 686-707) model of strategic networks in order to analyze how government policies (e.g. subsidies) will affect the stability and efficiency of networks of R&D collaboration among three firms located in different countries. A...

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...

The aim of this paper is to evaluate to what extent more transparency can reduce the occurrence of speculative attacks. It proposes a survey of the literature about the pros and cons of transparency on the exchange rate market, which is one of the main pillars of the new international financial...

The present paper develops a two-period, simple model of inter- bank competition based on the idea that banks can partially control the behaviour of borrowers. The control effort by one bank over its customers is not observable by competitor banks. It is shown that the equilibrium behaviour of...

Nous passons en revue quelques résultats récents sur la concrétisation des solutions concurrentielles d'économies où les agents ne disposent pas tous de la même information. Dans ce cadre, l'extension des définitions formalisées par Arrow et Debreu suscite de nombreuses difficultés...
