This paper exhibits a duality between the theory of revealed preference of Afriat and the housing allocation problem of Shapley and Scarf. In particular, it is shown that Afriat’s theorem can be interpreted as a second welfare theorem in the housing problem. Using this duality, the revealed...

Which and how many attributes are relevant for the sorting of agents in a matching market? This paper adresses these questions by constructing indices of mutual attractiveness that aggregate information about agents' attributes. The rst k indices for agents on each side of the market provide the...

In the context of the Beckerian theory of marriage, when men and women match on a single-dimensional index that is the weighted sum of their respective multi- variate attributes, many papers in the literature have used linear canonical correlation, and related techniques, in order to estimate...

Which and how many attributes are relevant for the sorting of agents in a matching market? This paper addresses these questions by constructing indices of mutual attractiveness that aggregate information about agents’ attributes. The first k indices for agents on each side of the market...

We propose a multivariate extension of Yaariʼs dual theory of choice under risk. We show that a decision maker with a preference relation on multidimensional prospects that preserves first order stochastic dominance and satisfies comonotonic independence behaves as if evaluating prospects using...

We revisit Machina's local utility as a tool to analyze attitudes to multivariate risks. Using martingale embedding techniques, we show that for nonexpected utility maximizers choosing between multivariate prospects, aversion to multivariate mean preserving increases in risk is equivalent to the...

Cet article illustre le lien entre identification partielle dans les modèles économétriques et critères de décision de Jaffray dans l'incertain non probabilisé à travers l'univers du choix de niveau optimal d'émissions toxiques dans un lac partagé entre deux communes.

La crise, apparue lors de l’été 2007, n’est pas une crise de la finance ou celle du capitalisme financier (qu’est-ce d’ailleurs qu’un capitalisme non financier ?). Elle est simplement une crise du capitalisme. Comment qualifier autrement un processus qui a combiné faillite de...

We investigate a model of one-to-one matching with transferable utility when some of the characteristics of the players are unobservable to the analyst. We allow for a wide class of distributions of unobserved heterogeneity, subject only to a separability assumption that generalizes Choo and...

We propose a multivariate extension of Yaari's dual theory of choice under risk. We show that a decision maker with a preference relation on multidimensional prospects that preserves ¯rst order stochastic dominance and satis¯es comonotonic in-dependence behaves as if evaluating prospects with...
