Ambiguity aversion is the exception
Kocher, Martin; Lahno, Amrei Marie; Trautmann, Stefan T. - 2015
An extensive literature has studied ambiguity aversion in economic decision making, and how ambiguity aversion can account for empirically observed violations of expected utility-based theories. Almost all relevant applied models presume a general dislike of ambiguity. In this paper, we provide...

Disagreement aversion
Bommier, Antoine; Fabre, Adrien; Goussebaïle, Arnaud; … - 2022
Experts often disagree. A decision-maker may be averse to such expert disagreement. Existing models of aversion to expert disagreement rest on ambiguity-averse preferences adopting a unanimity principle: If all experts consider one choice better than another, so should the decision-maker. Such...

Rule of law, institutional quality and information
Bruno, Randolph (contributor) - 2008
The focus of this paper is the analysis of the persistent lawlessness attitude observed in some transition and developing countries where an overall increase in the quality of institutions is recorded. The mechanism of information diffusion on institutional quality is explored using a model...

Optimal stopping under ambiguity
Riedel, Frank (contributor) - 2007
induction fails. If, however, the class of priors is time-consistent, we establish a generalization of the classical theory of … optimal stopping. To this end, we develop first steps of a martingale theory for multiple priors. We define minimax (super …

On freedom, lack of information and the preference for easy choices
Arlegi, Ritxar (contributor); Dimitrov, Dinko (contributor) - 2005
This paper is devoted to the study of opportunity sets comparisons when the sets may contain options whose characteristics are not completely known. We propose a suitable environment in which this problem can be approached, and provide axiomatic characterizations of several rules for ranking...

Portfolio inertia under ambiguity
Asano, Takao (contributor) - 2004 - [Elektronische Ressource]
We consider individual’s portfolio selection problems. Introducing the concept of ambiguity, we show the existence of portfolio inertia under the assumptions that decision maker’s beliefs are captured by an inner measure, and that her preferences are represented by the Choquet integral with...

Apportioning of risks via stochastic dominance
Eeckhoudt, Louis R. (contributor);  … - 2008
Consider a simple two-state risk with equal probabilities for the two states. In particular, assume that the random wealth variable Xi dominates Yi via ith-order stochastic dominance for i = M,N. We show that the 50-50 lottery [XN + YM, YN + XM] dominates the lottery [XN + XM, YN + YM] via (N +...
