In all health care systems exists governmental regulation, as the market for health is unanimously regarded as imperfect. The German health care market is a good example for strongly regulated market in nearly each submarket, partially the determination of prices. Reimbursement of health goods...

Der Einzelhandel in der Bandbreite seiner heutigen Erscheinungsformen hat auf der Angebotsseite sowie auf der Nachfrageseite in den zurückliegenden Jahrzehnten einen gravierenden Wandel vollzogen. Dabei ist eine generalisierende Beurteilung sehr schwierig, liegen doch zwischen SB-Warenhäusern,...

Bertrand competition under decreasing returns involves a wide interval of pure strategy equilibrium prices. We first present results of experiments in which two, three and four identical firms repeatedly interact in this environment. Less collusion with more firms leads to lower average prices....

We study collusive behaviour in experimental duopolies that compete in prices under dynamic demand conditions. In one treatment the demand grows at a constant rate. In the other treatment the demand declines at another constant rate. The rates are chosen so that the evolution of the demand in...

We study the relation between the number of firms and price-cost margins under price competition with uncertainty about competitors' costs. We present results of an experiment in which two, three and four identical firms repeatedly interact in this environment. In line with the theoretical...
