Human players, in contrast, ...
متن کاملThe Ultimatum Game Revisited
The starting point of this article is the result of one ultimatum game experiment one of many showing a huge deviation from the predictions of micro theory. However, further analysis gives an explanation of subject behavior that deserves to be seen as rational, if assumptions, such as a total secrecy resulting in no effects on reputation, are questioned. Respondersí actual behavior can be under...

The Ultimatum Game is a key exemplar that shows how human play often deviates from “rational” strategies suggested by game-theoretic analysis. One explanation is that humans cannot put aside the assumption of being in a multi-player multiround environment that they are accustomed to in the real world. We introduce the Social Ultimatum Game, a multi-player multi-round version of the classical Ul...
متن کاملThe Quantum Ultimatum Game
Classical game theory is a mathematical framework for decision problems with rational rules and rational players. It is used in many situations in economics, social sciences, communication and biology. An important item, leading to a solution, is the notion of non-cooperative Nash equilibrium. Given a payoff matrix P , a strategy vector x∗ is a Nash equilibrium if no player can improve his payo...
