Ambiguity and Ambiguity Aversion
Consider the following choice problem, known as “Ellsberg’s three-color urn example”, or simply the “Ellsberg Paradox” (Ellsberg [7]). An urn contains 30 red balls, and 60 green and blue balls, in unspecified proportions; subjects are asked to compare (i) a bet on a red draw vs. a bet on a green draw, and (ii) a bet on a red or blue draw vs. a bet on a green or blue draw. If the subject wins a ...
متن کاملAmbiguity Aversion in Game Theory: Experimental Evidence
This paper studies games with ambiguity averse agents, focusing on the relationship between preferences, beliefs over opponent’s preferences, and behaviour in normal form games. Using a carefully chosen 3×2 normal form game we find that a subject’s risk and ambiguity preferences affect the subject’s behaviour in normal form games in the direction suggested by economic theories. In contrast, we ...
متن کاملSmooth Ambiguity Aversion in the Small and in the Large
In this paper I use the smooth ambiguity model developed by Klibanoff, Marinacci, and Mukerji (2005) to define the concepts of ambiguity and uncertainty premia in a way analogous to what Pratt (1964) did in the risk theory literature. I show that those concepts may be useful to quantify the effect ambiguity has on the welfare of economic agents. I also provide local approximations of these prem...
متن کاملAre ambiguity aversion and ambiguity intolerance identical? A neuroeconomics investigation
In recent years, there has been growing interest in understanding a person's reaction to ambiguous situations, and two similar constructs related to ambiguity, "ambiguity aversion" and "ambiguity intolerance," are defined in different disciplines. In the field of economic decision-making research, "ambiguity aversion" represents a preference for known risks relative to unknown risks. On the oth...
متن کاملAmbiguity Aversion in Rhesus Macaques
People generally prefer risky options, which have fully specified outcome probabilities, to ambiguous options, which have unspecified probabilities. This preference, formalized in economics, is strong enough that people will reliably prefer a risky option to an ambiguous option with a greater expected value. Explanations for ambiguity aversion often invoke uniquely human faculties like language...
