The opportunity to tell a white lie (i.e., a lie that benefits another person) generates a moral conflict between two opposite moral dictates, one pushing towards telling always the truth and the other pushing towards helping others. Here we study how people resolve this moral conflict. What...

We consider the problem of identifying members of a group based on individual opinions. Since agents do not have preferences in the model, properties of rules that concern preferences (e.g., strategy-proofness and efficiency) have not been studied in the literature. We fill this gap by working...

This paper reports on the results of a series of experimental laboratory elections. The novelty of the design allows me to study both coordination failures and coordination efficiency in a repeated-game, divided majority setting. I assess and compare the performance of three voting mechanisms,...

This paper defines a fine C1-topology for smooth preferences on a "policy space", W, and shows that the set of convex preference profiles contains open sets in this topology. It follows that if the dimension(W)\leqv(𝒟)-2 (where v(𝒟) is the Nakamura number of the voting rule, 𝒟), then...

We discuss a central question in the study of courts: What do judges want? We suggest three different domains that might serve as the basic preferences of a judge: case dispositions and rules, caseloads and case mixes, and social consequences. We emphasize preferences over dispositions on the...
