The findings on the ultimatum game are considered as belonging to the most robust experimental results. In this paper we present a slightly altered version of the mini ultimatum game of Bolton and Zwick (1995). Whereas in the latter exactly equal splits were feasible in our games these were...

In standard rational choice modelling decisions are made according to given information and preferences. In the model presented here the 'information technology' of individual decision makers as well as their preferences evolve in a dynamic process. In this process decisions are made rationally...

We investigate simultaneous and sequential price competition in duopoly markets with differentiated products. In both markets symmetric firms are repeatedly and randomly matched. The strategy method is used to elicit behavior in the sequential market. We find that average leader prices in the...

Individuals differ in behavior since neither their ethical constraints, their attitudes towards risk, nor their analytical talents are the same. In an experimental prephase we tried to elicit such differences by confronting participants with suitable one-person-decision problems. In the main...

In this paper, we experimentally investigate the extended game with action commitment of Hamilton and Slutsky (1990). In their duopoly game, firms can choose their quantities in one of two periods before the market clears. If a firm commits to a quantity in period 1 it does not know whether the...
