"Stochastic Dominance and Preference for Randomization"
Tuesday, 25 April. 4 pm
Room 709 Boyd Orr Building

Abstract

Decision theorists usually take a normative view on stochastic dominance: a DM who chooses a lottery that puts more weight on options he likes less must be making a mistake. In this project, I argue that stochastic dominance violations may naturally occur in situations where anticipatory utility is high, such as going on a holiday trip. In such a situation, the DM may trade the certainty of going to his favourite destination for the excitement of not knowing where he will go. To document this phenomenon, I conduct an experiment in which participants make a series of binary choices between a sure destination and a lottery over holiday trips. The outcome of the lottery is revealed close to the date of travel. I vary the characteristics of the lotteries to understand when violations of stochastic dominance are most likely to occur and analyze their properties. I discuss the implications for the modelling of anticipatory utility.
