Experimental evidence from dictator games and simple choice situations indicates concerns for fairness and social welfare in human decision making. At the same time, models of inequality averse agents fail to explain the experimental data of individuals who reduce their payoff below a fair split...

In the present introductory work we propose an original analytical model of coopetitive game. We suggest possible general and feasible solutions; in particular, from a coopetitive perspective, we suggest compromise solutions - for our coopetitive game, by using Kalai-Smorodinsky method.

In a model of evolution driven by conflict between societies more powerful states have an advantage. When the influence of outsiders is small we show that this results in a tendency to hegemony. In a simple example in which institutions differ in their "exclusiveness" we find that these...

We experimentally investigate multiple notions of equity in ultimatum bargaining with asymmetric outside options. Building on the generalized equity principle formulated by Selten (1978), we derive three different equity rules that can explain 43% of all offers. Our within-subject design further...

We consider repeated games with transferable utility: players have an endowment of wealth in each period in which transfers can be made. We show that if endowments are large enough and the comon discount factor high enough, then a trongly renegotiation-proof equilibrium (SRP) in the sense of...

In repeated games with imperfect public monitoring, players can use public signals to perfectly coordinate their behavior. Our study of repeated games with imperfect private monitoring focusses on the coordination problem that arises without public signals.
