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...

Son preference is strong in Vietnam, according to attitudinal surveys and studies of contraceptive prevalence and birth hazards. These techniques assume a single model is valid for all families, but it is more plausible that son preference is found for some, but not all, families. Heterogeneous...

We consider a kernel based approach to nonlinear canonical correlation analysis and its implementation for time series. We deduce various diagnostics for reversible processes and gaussian processes. The method is first applied to a stimulated series satisfying a diffusion equation allowing us to...

Multinational enterprises (MNEs) have started to populate also regulated sector. Their linked international activities and credible threats to relocate are then new concerns for regulators. We sutdy a multiprincipal model in which a privately informed MNE (the agent) produces for two countries...
