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

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

We derive the empirical content of an instrumental variables model of sectorial choice with binary outcomes. Assumptions on selection include the simple, extended and generalized Roy models. The derived bounds are nonparametric intersection bounds and are simple enough to lend themselves to...

We show that confidence regions covering the identified set may be preferable to confidence regions covering each of its points in robust control applications.

In the spatial model of voting, voters choose the candidate closest to them in the ideological space. Recent work by (Degan and Merlo 2009) shows that it is falsifiable on the basis of individual voting data in multiple elections. We show how to tackle the fact that the model only partially...
