I study the effect of sunk entry-costs on potential competition in a multi-market framework, where potential entrants have different home market profits. Although sunk-entry-costs are supposed to increase entry barriers, my experimental results suggest that firms view entry costs differently...

Economic integration is defined as the elimination of economic borders between two or more savings. In turn, an economic border demarcation over which any actual or potential mobility of goods, services and factors of production and communication flows, is relatively low. On both sides of a...

In the framework Hotelling-Downs competition two players can freely choose a position along a one-dimensional market. We introduce restrictions of feasible strategies and analyze the consequences for players and consumers. In equilibrium players may minimally differentiate away from the center...

The existing literature on "two-sided markets" addresses participation externalities, but so far it has neglected pecuniary externalities between competing platforms. In this paper we build a model that incorporates both externalities. In our setup differentiated platforms compete in advertising...

Linear demand formulations for price competition in horizontally differentiated products are sometimes used to compare situations where additional varieties become available, e. g. due to market entry of new firms. We derive a consistent demand system to analyze such situations.

For several years, an increasing number of firms are investing in Open Source Software (OSS). While improvements in such a non-excludable public good cannot be appropriated, companies can benefit indirectly in a complementary proprietary segment. We study this incentive for investment in OSS. In...
