On ambiguity-averse market equilibrium
AbstractWe develop a Nash equilibrium problem representing a perfectly competitive market wherein all players are subject to the same source of uncertainty with an unknown probability distribution. Each player—depending on her individual access to and confidence over empirical data—builds an ambiguity set containing a family of potential probability ...

Good luck, bad luck, and ambiguity aversion [PDF]
We report a series of experiments investigating the influence of feeling lucky or unlucky on people's choice of known-risk or ambiguous options using the traditional Ellsberg Urns decision-making task.

Value-at-risk under ambiguity aversion
This study explored the effects of ambiguity on the calculation of Value-at-Risk (VaR) using a mathematical model based on the theory of Choquet-Brownian processes. It was found that while a moderate degree of ambiguity aversion yields a higher value for

Ambiguity Aversion and Variance Premium [PDF]
This paper oers an ambiguity-based interpretation of variance premium— the dier- ence between risk-neutral and objective expectations of market return variance— as a com- pounding eect of both belief distortion and variance dierential regarding the uncertain economic regimes.

An examination of ambiguity aversion: Are two heads better than one?
Ambiguity aversion has been widely observed in individuals’ judgments. Using scenarios that are typical in decision analysis, we investigate ambiguity aversion for pairs of individuals.

Ellsberg Paradox: Ambiguity And Complexity Aversions Compared [PDF]
We present a simple model where preferences with complexity aversion, rather than ambiguity aversion, resolve the Ellsberg paradox. We test our theory using laboratory experiments where subjects choose among lotteries that “range” from a simple risky ...

Measuring and Disentangling Ambiguity and Confidence in the Lab
In this paper we present a novel experimental procedure aimed at better understanding the interaction between confidence and ambiguity attitudes in individual decision making.

Updating Ambiguity Averse Preferences [PDF]
Dynamic consistency leads to Bayesian updating under expected utility. We ask what it implies for the updating of more general preferences. In this paper, we characterize dynamically consistent update rules for preference models satisfying ambiguity aversion. This characterization extends to regret-based models as well.

Measuring Ambiguity Aversion: A Systematic Experimental Approach [PDF]
This paper provides a systematic analysis of individual attitudes towards ambiguity, based on laboratory experiments. The design of the analysis allows to capture individual behavior across various levels of ambiguity, ranging from low to high. Attitudes
