We justify risk neutral equilibrium bidding in commonly known fair division games with incompleteinformation by an evolutionary setup postulating (i) minimal common knowledge, (ii) optimal responses to conjectural beliefs how others behave and (iii) evolutionary selection of conjectural beliefs...

Leaky-bucket transactions can be regarded as income transfers allowing for transaction costs. In its most rudimentary form, leaky-bucket transactions trace out the maximum leakageʺ of transaction costs before income inequality is exacerbated, or before a welfare loss is experienced. This notion...

We study fairness and reciprocity in a Hawk-Dove game. This alllows us to testvarious models in one framework. We observe a large extent of selfish and rationalbehavior. Our results are inconsistent with leading models in this field.
