Measuring risk preferences in the field is critical for policy, however, it can be costly. For instance, the commonly used measure of Holt and Laury (2002) relies on a dozen lottery choices and payments which makes it time-consuming and costly. We propose a short version of the Holt and Laury...

There is a large literature showing that willingness-to-accept (WTA) is usually much higher than willingness-to-pay (WTP) in empirical studies although they should be roughly equal according to traditional economic theory. A second stream of literature shows that people are typically ambiguity...

Popular models for decision making under ambiguity assume that people use not one but multiple priors. This paper is a first attempt to experimentally elicit the min and the max of multiple priors directly. In an ambiguous scenario we measure a participant's single prior, her min and max of...

We examine how different welfarist frameworks evaluate the social value of mortality risk-reduction. These frameworks include classical, distributively unweighted cost-benefit analysis — i.e., the “value per statistical life” (VSL) approach — and three benchmark social welfare functions...

Experimental studies of the WTP-WTA gap avoid social trading by implementing an incentive compatible mechanism for each individual trader. We compare a traditional random price mechanism and a novel elicitation mechanism preserving social trading, without sacrificing mutual incentive...
