Probabilistic social preference: how Machina’s Mom randomizes her choice

Research output: Contribution to journalArticlepeer-review


We experimentally investigate preference for randomization in social settings, in which the dictator chooses probabilistically between two allocations for herself and an anonymous recipient. We observe substantial proportions of subjects choosing to randomize under various circumstances. The observed patterns have rich implications for various assumptions in social preference models and shed light on recent studies on ex-ante and ex-post social preferences.
