We show that observed choices in discounting experiments are consistent with roughly one-half of the subjects using exponential discounting and one-half using quasi-hyperbolic discounting. We characterize the latent data generating process using a mixture model which allows different subjects to...

We elicit individual preferences over social risk. We identify the extent to which these preferences are correlated with preferences over individual risk and the well-being of others. We examine these preferences in the context of laboratory experiments over small, anonymous groups, although the...

Voting rules over three or more alternatives suffer from a general problem of manipulability. However, if the rule is 'difficult' to manipulate, in some formal computational sense that is intrinsic to the rule or some cognitive sense specific to the set of voters, then one might not observe...
