How do you play the ultimatum game?
In the ultimatum game (Güth et al., 1982), the proposer’s role is to offer a split of the initial endowment between herself and the responder. The responder can then either accept the split and both players walk away with their designated portion, or refuse the split and both players get US$0.
What does the ultimatum game prove?
The ultimatum game is important from a sociological perspective, because it illustrates the human unwillingness to accept injustice. The tendency to refuse small offers may also be seen as relevant to the concept of honour.
Is the ultimatum game a simultaneous game?
It is a one-shot game covering the behavior of one responder with one or two proposers. Each participant provides answers for all cases in both roles. The one-shot game divides into two blocks: first the standard ultimatum game and second its simultaneous as well as sequential expansions (compare Table 1).
What is the SPNE of an ultimatum game?
The Ultimatum Game is a paradigmatic two-player game. A proposer can offer a certain fraction of some valuable good. A responder can accept the offer or reject it, implying that the two players receive nothing. The only subgame-perfect Nash equilibrium is to only offer an infinitesimal amount and to accept this.
What is the sub perfect Nash equilibrium in your ultimatum game?
Where is the Nash equilibrium in the ultimatum game?
If f(p) = “accept” the first receives p and the second x-p, otherwise both get zero. (p, f) is a Nash equilibrium of the Ultimatum game if f(p) = “accept” and there is no y > p such that f(y) = “accept” (i.e. p is the largest amount the second will accept).
Is the ultimatum game a sequential game?
The Ultimatum Game is a famous asymmetric, sequential two-player game intensely studied in Game Theory.
What is the Nash equilibrium in the ultimatum game?
(p, f) is a Nash equilibrium of the Ultimatum game if f(p) = “accept” and there is no y > p such that f(y) = “accept” (i.e. p is the largest amount the second will accept). The first player would not want to unilaterally increase her demand since the second will reject any higher demand.
Is fairness important in the ultimatum game?
In this paper, we develop an evolutionary approach to the Ultimatum Game. We show that fairness will evolve if the proposer can obtain some information on what deals the responder has accepted in the past. Hence, the evolution of fairness, similarly to the evolution of cooperation, is linked to reputation.
