Abstract
Salience theory and Regret Theory predict that choices between two lotteries are driven not only by the marginal distributions of the lotteries, but also by the correlation between the two lotteries. In particular, both theories predict a preference for relative skewness. Our previous work has documented a precisely estimated null effect of relative skewness on non-repeated lottery choices. In a setting in which participants make repeated choices with outcome feedback, we observe a strong tendency to choose lotteries with a negative relative skewness. In this pilot, we explore whether similar choice patterns obtain in a setting in which, instead of outcome feedback on their past choices, individuals receive sample draws from the lotteries they choose from.

Experimental Details

Interventions

Intervention(s)
We run an online experiment with students from Renmin University of China.Participants make multiple repeated choices between two lotteries and answer a survey. Five participants are selected randomly. For each of these five participants, one of the lottery choices is randomly selected, and participants are paid on the basis of this choice.

For a detailed description of the experimental design and the lotteries we employ, see the document "Experiment_design".

Primary Outcomes

Primary Outcomes (end points)
Choice reversals due to changes in the correlation structure, and frequency of choices of the lottery with a higher relative skewness.
