The preemptive role of capital is analysed in a class of two-player symmetric capital accumulation differential games with reversible investment. It is proved that, in the medium run, the firm with better initial condition exploits its advantage when the game features feedback substituability....

L'adoption d'une Banque centrale commune modifie la structure des relations strategiques entre les autorites fiscales et monetaires. Cet article etudie, dans un cadre dynamique, comment une telle recomposition affecte a long terme les grandeurs macroeconomiques deficits, seigneuriages et dettes....

In economic two players games with negative (positive) spillovers it is well-known that symmetric agents both overact (underact) at the Nash Equilibria. We show that for heterogeneous agents this rule has to be amended if the game features strategic substituability.

Dans un jeu differentiel d'accumulation de capital a deux joueurs avec investissement reversible nous proposons une methode simplificatrice pour calculer l'equilibre de Nash en boucle ouverte. nous calculons aussi la solution centralisee et nous comparons les deux resultats a travers leurs...

Problems of intergovernmental policy coordination can take many forms and are becoming increasingly important with continuing economic integration. In this paper we focus on the fiscal competition problem where the non-cooperative choice of taxes and transfers among government typically leads to...

Nous montrons à l’aide de l’enquête Logement que les personnes d’origine africaine sont surreprésentées dans les grandes agglomérations et tendent à s’y fixer dans des proportions beaucoup plus importantes que les personnes d’origine française. Deux raisons expliquent ce...

This paper examines the normative properties of an empirically implementable dominance criterion for comparing alternative distributions of two attributes, one of which being cardinally measurable, between an arbitrary number of individuals. The criterion, which generalizes the one proposed by...

This paper examines how allowing individuals to emigrate to pay lower taxes changes the optimal non-linear income tax scheme in a Mirrleesian economy. Type-dependent participation constraints are borrowed from contract theory. An individual emigrates if his domestic utility is less than his...

Consider a developing country that has the potential for biodiversity conservation, and developed countries that benefit from biodiversity but are not in position to produce it. From the statu quo, some incremental protections of biodiversity would be harmful for the developing country but would...

inequality decreases and welfare increases as a result of a progressive transfer. We explore the implications for welfare and inequality measurement of substituting the weaker absolute differentials and deprivation quasi-orderings for the Lorenz quasi-ordering. Restricting attention to...
