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...

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...

In a school choice context we show that considering only schools' priorities and the set of acceptable schools for each student - but not how these schools are ranked in their preferences - we can restrict the set of possible stable matchings that can arise for any preference profile of the...

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...

Contrary to most countries, the recruitment of assistant professors in France is centralized: recruitment committees submit a ranking of candidates to the Ministry of Education, the candidates submit their own ranking over the faculties that rank them and the Ministry compute the final match...
