We identify a natural counterpart of the standard GARP for demand data in which goods are all indivisible. We show that the new axiom (DARP, for "discrete axiom of revealed preference") is necessary and sufficient for the rationalization of the data by a well-behaved utility function. Our...

Alvin Roth et Lloyd Shapley ont reçu en 2012 le prix de sciences économiques de la Banque Royale de Suède à la mémoire d'Alfred Nobel, pour leurs travaux sur l'organisation centralisée de certains marchés économiques, qui dépendent de l'appariement d'agents de deux types distincts (des...

According to a minimalist version of Afriat's theorem, a consumer behaves as a utility maximizer if and only if a feasibility matrix associated with his choices is cyclically consistent. An essential experiment consists of observed consumption bundles (x_1,..., x_n) and a feasibility matrix...

The folk theorem characterizes the (subgame perfect) Nash equilibrium payoffs of an undiscounted or discounted infinitely repeated game - with fully informed, patient players - as the feasible individually rational payoffs of the one-shot game. To which extent does the result still hold when...

Le recrutement des enseignants-chercheurs en France est centralisé. Le ministère calcule les affectations en fonction des listes de classements soumis par les comités de sélection et des listes de voeux soumis par les candidats. Les enjeux stratégiques du recrutement en France sont souvent...
