The relationship between technical progress and price competition is a controversial issue in economics. This paper highlights the fact that investment in technical progress is an authentic type of competition which benefits the consumers rather than the industry. This type of competition exists...

In his book on 'Market Microstructure' Spulber presented some strange results with respect to the impact of the substitutability parameter in an intermediation model with differentiated products and inputs. Intuitively, effects in the product and the input market should be similar: if firms...

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...

Using a model with switching costs it is shown that firms may have an incentive to set up a new firm supplying to the same market under quite general conditions. The new firm attracts some market share of the founding firm. The start up firm is thus an act of cannibalization. Moreover, entry of...

We analyze Bertrand duopoly competition in markets with network effects and consumer switching costs. Depending on the ratio of switching costs to network effects, our modelerates four different market patterns: monopolization and market sharing which can be either monotone or alternating. A...

We study the profitability and welfare effects of merger in a strategic trade policy environment. Merger changes the strategic trade policy equilibrium. We show that merger can be profitable and welfare enhancing here, even though it is not profitable in a laissez-faire economy. A key element is...

In this note we consider the preferences of a profit maximizing firm for international ownership in a world in which firms compete in an international Cournot oligopoly, and in which countries use strategic trade policy. We find that firms prefer national ownership and show that full...
