The classical price (quantity) discrimination model relies on the assumption that the consumers can neither buy more than one bundle each, nor resell the goods to each other. This assumption is lifted. In a two-type context, the consumers' set strategy is enlarged, first to allow for multiple...

An encompassing test between two models is based on the idea that the first model is able to explain the inference obtained by the second model. In a Bayesian Framework, the posterior distribution of the second model will then be compared to the posterior distribution built in hte first model...

This paper considers the repetition of a finite two person game when each player knows an upper bound on the length of the game, but assigns a positive probability to his opponent overestimating the length of the game. It is shown that with sufficiently little discounting, any payoff vector that...

This paper formalises a three-tier administrative hierarchy. A benevolent federal government must decide how to fund an indivisible local public work, planned to be undertaken by a single firm. But the federal government observes neither the cost nor the local benefit of the project. To obtain...

Dans cet article, j'etudie le comportement d'un certain nombre de firmes en concurrence sur un marche sur lequel la demande decroit de maniere exogene. Je verifie que la fusion de toutes les entreprises presentes sur le marche, qui engendre une situation de monopole, est toujours avantageuse en...

This article investigates the issue of predation by a regulated firm. Since it has private information, a regulated firm obtains higher rents incase of successful predation: the fewer the competitors, the higher the marginal social value of the regulated firm's effort and the higher the...

This paper explores the implications of different institutional arrangements for allocating policy-making authority among confederated districts. Using a variation on the spatial model of political competition, we compare different rules for aggregating preferences acrossthese jurisdictions,...

Nous adoptopns dans cet article la notion d'equilibre approximatif obtenu a partir d'une regle intuitive. Cette notion repose sur l'idee qu'a la place des strategies complexes a l'equilibre de Nash, les agents utilisent des regles de decision simples et fondees sur l'intuition et le bon sens....

Sliced inverse regression is a dimension reduction technique for exploring non-linear relationships between an output variable and a vector of input variables. Motivated by a data set of income distributions and economic indicators of french cities, we adress the problem of modelling a family of...
