In the literature of psychology and economics it is frequently observed that individuals tend to imitate similar individuals. A fundamental question is whether the outcome of such imitation can be consistent with self-interested behaviour. We propose that this consistency requires the existence...

We conducted an experimental study of price competition in a duopolistic market. The market was operationalized as a repeated game between two “teams” with one, two, or three players in each team. Each player simultaneously demanded a price, and the team whose total asking price was smaller...

Experimental sealed bid first price auctions with private values in which feedback on the losing bids is provided yield lower revenues than auctions where this feedback is not given. Furthermore, bids tend to be above the equilibrium predictions for risk neutral bidders. While the latter...

The paper re-expresses and complements arguments against the normative validity of expected utility theory in Robin Pope (1983, 1991a, 1991b, 1985, 1995, 2000, 2001, 2005,2006, 2007). The objections concern the neglect of the evolving stages of knowledge ahead (stages of what the future will...

Understanding how physicians respond to incentives from payment schemes is a central concern in health economics research. We introduce a controlled laboratory experiment to analyse the influence of incentives from fee-for-service and capitation payments on physicians’ supply of medical...

This is a reply to "Stationary Concepts for Experimental 2 X 2 Games: Comment" by Brunner, Camerer, and Goeree which corrects some computational errors in Selten and Chmura (2008) and extends the comparison of five stationary concepts to data from previous experimental studies. We critically...

It is a widely held belief that in imperfect markets the tendency to cooperate depends on the number of competitors. E.H. Chamberlin's distinction between the small group and the large group is based on this assumption. Cooperative forms of behaviour like joint profit maximization are assumed to...

It is the purpose of this paper to present the example of a simple game in extensive form where the actual behavior of well informed players cannot be expected to agree with the clear results of game theoretical reasoning. A story about a fictitious chain store and its potential competitors is a...

Bipolar games are normal form games with two pure strategies for each player and with two strict equilibrium points without common equilibrium strategies. A normal form game has linear incentives, if for each player the difference between the payoffs for any two pure strategies depends linearly...

The concept of a perfect equilibrium point has been introduced in order to exclude the possibility that disequilibrium behavior is prescribed on unreached subgames. (Selten 1965 and 1973). Unfortunately this definition of perfectness does not remove all difficulties which may arise with respect...
