This paper studies data from the wholesale fruit and vegetables market in Marseille. The special feature of the data is that we have details of counteroffers to the prices that were proposed by the seller even when no transaction took place. Each offer, counteroffer and refusal conveys...

In equal punishment games first the proposer suggests how to split the pie, i.e. a positive monetary reward. Unlike in the ultimatum game, the responder can decide among many (for proposer and responder) equal penalty payments. To exclude negative payoffs, punishment was bounded from above...

The general framework of decision emergence (Güth, 2000a) is applied to the specific decision task of a proposer in ultimatum bargaining, i.e. to choosing how much the responder should be offered. For this purpose the "Master Module" as well as its submodules "New Problem Solver", "Adaptation...

Starting point of our (indirect) evolutionary analysis is the sequential bargaining model of Manning (1987) who distinguishes between trade union's power in initial wage and in later employment negotiations. By linking two such collective bargaining situations we can say which of the two...

The game theoretic prediction for alternating offer bargaining depends crucially on how “the pie” changes over time, and whether the proposer in a given round has ultimatum power. We study experimentally eight such bargaining games. Each game is once repeated before moving on to the next one...

On May 11, 2001, readers of the Berliner Zeitung were invited to participate in an ultimatum bargaining experiment played in the strategy vector-mode: Each participant chooses not only how much (s)he demands of the DM 1.000-pie but also which of the nine possible offers of DM 100, 200, ..., 900...

Adopting the indirect evolutionary approach, we show that it might be beneficial for firms on a heterogeneous market not only to care for their profits but also for their respective customers' welfare. -- evolutionary stability ; customer orientation ; heterogenous market ; duopoly
