Procedures are the area where fairness arguably has its largest influence on modern societies. The experiments we report provide an initial characterization of that influence and suggest new interpretations for some well-known results. We find that procedural fairness is conceptually distinct...

In both dictator and impunity games, one player, the dictator, divides a fixed amount of money between himself and one other, the recipient. Recent lab studies of these games have produced seemingly inconsistent results, reporting substantially divergent amounts of dictator giving. Also, one...

Does social network structure influence coordination? We examine a coordination game in which each player engages with an exogenously connected “local” subset of the player population, the pattern of links defining a social network. Players know the number of local links they possess but...
