On the Merits of Separate Spaces: Why Institutions Isolate Cooperation and Division Tasks Apr 8, 2026 Scott Bokemper; Gregory Huber, 2024, "On the Merits of Separate Spaces: Why Institutions Isolate Cooperation and Division Tasks", https://doi.org/10.60600/YU/WKZMNB, Yale Dataverse, V2 Do institutions shape the possibility of sustaining cooperation when the same individuals must first divide resources and then attempt to cooperate? It could be that simply having received an inequitable division undermines cooperative behavior, reducing aggregate welfare. Alternatively, it might be that only when interacting with the same individu...

Less explored is whether providing information about why pay in...
