Simple games are a powerful tool to analyze decision-making and coalition formation in social and political life. In this paper we present relational models of simple games and develop relational algorithms for solving some game-theoretic basic problems. The algorithms immediately can be...

In a simple public good economy, we propose a natural bar- gaining procedure, the equilibria of which converge to Lin- dahl allocations as the cost of bargaining vanishes. The pro- cedure splits the decision over the allocation in a decision about personalized prices and a decision about output...

We introduce a description of the power structure which is inherent in a strategic gameform using the concept of an interaction sheaf. The latter assigns to each open set of outcomes a set of interaction arrays, specifying the changes that coalitions can make if outcome belongs to this open set....

This paper focuses on the influence on the general equilibrium of an economy of the opening of markets of allowances, such as the European Union Emission Trading Scheme. Assuming there existed an equilibrium before the opening of allowances' markets, we describe the changes in the firms behavior...

This paper evaluates the role of economic geography in explaining regional wages in China. It investigates the extent to which market proximity can explain the evolution of wages, and through which channels. We construct a complete indicator of market access at the provincial level from data on...

We study the stability and the stability index of the meet game form defined on a meet semilattice. Given any active coalition structure, we show that the stability index relative to the equilibrium, to the beta core and to the exact core is a function of the Nakamura number, the depth of the...

In this paper, we assess the success of the ongoing financial system reforms in China by investigating the extent to which firms are financially constrained. We focus on the role played by Foreign Direct Investment (FDI) in funding the Chinese corporate sector, and analyze whether incoming...

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, where the network speciÖes the nature of the relationship...

Le 12 octobre 2009 Elinor Ostrom recevait le Prix Nobel d'économie pour sa contribution à l'analyse des biens collectifs. Cet article se propose de dresser un panorama de ses travaux. Nous commencerons par retracer l'itinéraire académique et professionnel d'Ostrom. Dans une deuxième partie,...

In this note we make a comparison between the class of monotonic TU cooperative games and the class of superadditive TU cooperative games. We first provide the equivalence between a weakening of the class of su- peradditive TU games and zero-monotonic TU games. Then, we show that zero-monotonic...
