We compare the behaviour of students and professional traders from an influential German bank in an experiment involving financial options. The arbitrage free option price is independent of the probability distribution of the underlying asset. The experimental data uncover a probability...

This paper reports on an experiment designed to examine the effects of small-scale changes in wealth on risk attitudes. We find that the money given prior to risky choices does not induce a change of subjects' risk preferences. This result supports a key assumption in a recent literature over...

This paper provides sufficient and partially necessary conditions for the equivalence of Nash and evolutionary equilibrium in symmetric games played by finite populations. The focus is on symmetric equilibria in pure strategies. The conditions are based on properties of the payoff function that...

This paper extends the Baron-Ferejohn model of legislative bargaining to general weighted majority games with two modifications: first, payoff division can only be agreed upon after the coalition has formed (two-stage bargaining); second, negotiations in the coalition can break down, in which...

This paper makes three related contributions to noncooperative game theory: (i) a solution concept (the “ICEU solution”), which is generated by an iterative procedure that constructs trinary partitions of strategy sets and deals with problems arising from weak dominance; (ii) a class of models...
