We repeatedly elicited individuals? Willingness to Accept (WTA) evaluations for an auctioned bad in an experimental setting in which truthful revelation is the (weakly) dominant strategy. We investigate whether the observation of supposedly irrelevant signals (the market price, the asks at...

We repeatedly elicited individuals' Willingness to Accept (WTA) evaluations for an auctioned bad in an experimental setting in which truthful revelation is the (weakly) dominant strategy. We investigate whether the observation of supposedly irrelevant signals (the market price, the asks at...

Conformity behavior, i.e., the agreement between an individual’s choices and the prevailing behavior of a reference group, is a commonly observed phenomenon. Though some types of social interactions may give raise to specific incentives to adopt either a majoritarian or a contrarian behavior,...

We provide a simple model of credit rationing with endogenous occupational chioce. Entrepreneurial talent is subject to private information and to screen borrowers banks ask for collateral. The interplay between the labour market and the credit market leads to multiple equilibria in a natural...

We show that the monotone continuity condition introduced by Villegas (1964) and Arrow (1970) is the behavioral counterpart of countable additivity (and relative weak compactness) in a multiple priors model. This generalizes their original result, in which the special case of a singleton set of...

The objective of this paper is to show how ambiguity, and a decision maker (DM)'s response to it, can be modelled formally in the context of a very general decision model. In the first part of the paper we introduce an "unambiguous preference" relation derived from the DM's preferences, and show...

We exhibit a general class of interactive decision situations in which all the agents benefit from more information. This class includes as a special case the classical comparison of statistical experiments a la Blackwell.

The asymptotics of large deviation probabilities for two-sample non degenerate von Mises functionals and U- statistics of arbitrary degree is investigated. We find explicitly the main term of this asymptotics. Some examples motivated by nonparametric statistics are given. The result may be...
