We analyze how sharing rules affect Nash equilibria in Bertrand games, where the sharing of profits at ties is a decisive assumption. Necessary conditions for either positive or zero equilibrium profits are derived. Zero profit equilibria are shown to exist under weak conditions if the sharing...

We examine a model of price competition with strictly convex costs where the firms simultaneously decide on both price and quantity, are free to supply less than the quantity demanded, and there is discrete pricing. If firms are symmetric then, for a large class of residual demand functions,...

Industrial organization is mainly concerned with the behavior of large firms. Experimental industrial organization therefore faces a problem: How can firms be brought into the laboratory? The main approach relies on framing: Call individuals firms! This experimental approach is not in line with...

We report results from a Cournot triopoly experiment with different subject pools: German students, Malaysian students, and Malaysian managers. While German students play Nash, we reject the hypothesis that both Malaysian students and managers select the Nash quantity. Moreover, Malaysian...

This paper further develops the standard modelling of information exchange between firms in the presence of cost uncertainty. In order to avoid consistency problems, we replace the normal distribution of the random variables, commonly used because of its convenient mathematical properties, by an...

This study investigates the impact of pre-play communication on the outcomes in Cournot duopoly and triopoly experiments, using both students and managers as subjects. Communication is implemented by two different devices, a 'standardized-communication' and a free-communication device. We find...

In bisherigen Untersuchungen der Auswirkungen aktienkursorientierter Management-Entlohnung auf den Preiswettbewerb wurden Nachfrageschwankungen nicht berücksichtigt. Der vorliegende Beitrag zeigt, dass Manager auch dann eine größere Kollusionsneigung besitzen als Eigentümer, wenn sich die...

We show that concealing cost information is a dominant strategy in heterogeneous Bertrand oligopolies. This result enables us to endogenize the number of firms in a market in terms of market size, entry costs, and unit cost uncertainty.

Unternehmen müssen nicht immer Kollusionsabsichten verfolgen, wenn sie untereinander Informationen austauschen. Dieser Beitrag zeigt, daß bei Nachfrageunsicherheit auch strikt kompetitive Konkurrenten private Informationen bezüglich ihrer Nachfragebedingungen preisgeben. Dies läßt sich in...

This paper further develops the standard modelling of information exchange between firms in the presence of demand uncertainty which applies to firms in new industries and insecure regions or markets. We replace the normal distribution of the random variables, commonly used because of its...
