Allocations familiales et autres transferts cibles sont generalement verses aux meres, sur la base de l`observation qu`augmenter la part des ressources controlees par les meres conduit a ameliorer le bien-etre des enfants. Nous recensons un ensemble de resultats empiriques qui etablisent le...

This paper is concerned with the incentive properties of the Matthew Effect by which since Merton [1968] one is usually describing the various cumulative advantages that obviously affect academic competition. We introduce a model of sequential contests in which the agents that have initially...

We consider a dynamic version of sender-receiver games, where the sequence of states follows an irreducible Markov chain observed by the sender. Under mild assumptions, we provide a simple characterization of the limit set of equilibrium payoffs, as players become very patient. Under these...

This paper deals with the distribution of seats between municipalities in the inter-communal council (EPCI) of Martinique and Guadeloupe. In each of the EPCIs, we calculate the voting power of municipalities using the Shapley-Shubik and Banzhaf indices. Our analysis allows us to show that in...

The purpose of this master thesis is to have in a simple and detailed way the significant results of social choice theory and to study the resource sharing (goods or responsibilities) between petitioning agents in a proof of election. While analyzing social choice functions more insight, we...

Nous considérons la vente aux enchères sous pli scellé au second prix d'un objet que chaque acquéreur potentiel évalue de manière « privée et indépendante ». Nous montrons que l'optimum ex ante d'un cartel, sous contraintes d'incitation et d'équilibre ex post des transferts, coïncide...

(VF)L’objectif de cet article est d’essayer de comprendre pourquoi certaines entreprises sont amenées à renégocier leurs contrats d’externalisation. Notre postulat de départ est que le nombre de renégociations augmente avec le temps écoulé depuis la signature du contrat. Nous...

We study the development of a duopoly industry -evolution of firm capacities and competitive behavior- in a continuous-time real-options model of capacity investment. Our methodology allows the evaluation of investment options and exercise rules in a strategic setup. In the initial industry...

We study a simple duopoly model of preemption with multiple investments and instantaneous Bertrand competition in a stochastically growing market. Different patterns of equilibria may arise, depending on the importance of the real option effect. If the average growth rate of the market is close...
