We examine the risky choices of contestants in the popular TV game show “Deal or No Deal” and related classroom experiments. Contrary to the traditional view of expected utility theory, the choices can be explained in large part by previous outcomes experienced during the game. Risk aversion...

Betrayal aversion has been operationalized as the evidence that subjects demand a higher risk premium to take social risks compared to natural risks. This evidence has been first shown by Bohnet and Zeckhauser (2004) using an adaptation of the Becker-DeGroot-Marshak mechanism (BDM, Becker et al....

This paper sets out an ordinal theory of choice under risk that is capable of replicating and extending important results obtained in the EU framework and is yet far more descriptive and no less tractable at the same time. Focusing on decision problems where attitudes towards risk and...

Arad and Rubinstein (2012, AER) proposed the 11-20 money request game as an alternative to the P beauty contest game for measuring the depth of thinking. In this paper, we find that choices in the 11-20 game are confounded with risk aversion; hence, the depth of thinking measured is confounded...

Using choices among hypothetical income lotteries from respondents to a large Norwegian survey, we analyse the association between attitudes towards risks and socio-economic characteristics by means of an ordered probit model. Next, we impute a risk aversion measure to every respondent and use...

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...

A decision maker bets on the outcomes of a sequence of coin-tossings. At the beginning of the game the decision maker can choose one of two coins to play the game. This initial choice is irreversible. The coins can be biased and the player is uncertain about the nature of one (or possibly both)...

Everyone remembers a plot where a disadvantaged individual facing the prospect of failure, spends more effort, turns around the game and wins unexpectedly. Most tournament theories, however, predict the opposite pattern and see the disadvantaged agent investing less effort. We show that 'turn...

We investigate whether there is a link between conditional cooperation and betrayal aversion. We use a public goods game to classify subjects by type of contribution preference and by belief about the contributions of others; and we measure betrayal aversion for different categories of subject....
