Preference for Randomization: Ambiguity Aversion and Inequality Aversion [PDF]

open access: yes, 2010
In Anscombe and Aumann’s (1963) domain, there are two types of mixtures. One is an ex–ante mixture, or a lottery on acts. The other is an ex–post mixture, or a state–wise mixture of acts.

Unraveling Ambiguity Aversion

open access: yesReview of Economics and Statistics, 2023
Abstract We report the results of two experiments designed to better understand the mechanisms driving decision-making under ambiguity. We elicit individual preferences over different sources of uncertainty, entailing different degrees of complexity, from subjects with different sophistication levels.

Are Policymakers Ambiguity Averse?* [PDF]

open access: yesThe Economic Journal, 2019
Abstract We investigate the ambiguity preferences of a unique sample of real-life policymakers at the Paris UN climate conference (COP21). We find that policymakers are generally ambiguity averse. Using a simple design, we are moreover able to show that these preferences are not necessarily due to an irrational behavior, but rather to ...

Randomization and Ambiguity Aversion [PDF]

open access: yesEconometrica, 2020
We propose a model of preferences in which the effect of randomization on ambiguity depends on how the unknown probability law is determined. We adopt the framework of Anscombe and Aumann (1963) and relax the axioms. In the resulting representation of the individual's preference, the individual has a collection of sets of priors

This study investigates insurance demand in a two-period model when a decision-maker (DM) is averse to the ambiguity of loss distributions. This study derives sufficient conditions such that the ambiguity-averse DM purchases more insurance than an ...

Ambiguity Aversion and Underdiversification [PDF]

open access: yesJournal of Financial and Quantitative Analysis, 2013
We examine asset allocation decisions under smooth ambiguity aversion when an investor has a prior degree of belief in the domestic capital asset pricing model (CAPM). Different from a Bayesian approach, the investor separately relies on the conditional distribution of returns and on the posterior over parameters to make decisions, rather than on the ...
