We study in this paper location equilibria for a symmetrical two-store duopoly selling complementary varieties, both on the linear and the circular markets. In contrast to the existing literature, besides assuming that each affiliate produces a different complementary variety, we equally...

We study location equilibria for a symmetrical two-store duopoly selling differentiated products on the circle market. In contrast to the existing literature, we assume that each store sells a different product. We consider both complementarity among all varieties on the market and intra-firm...

This paper focuses on multi-store sequential locations between two firms within a confined geographical area over the short term. Based on the model of Teitz (1968), we incorporate a fixed cost for opening stores, as well as every possible asymmetry regarding an upper limit on the number of...

The present paper analyses the effects on social welfare of a partial crossparticipation at ownership level in a differentiated Cournot duopoly. We show that cross-participation, despite the fact it appears as an anti-competitive practice which reduces the degree of market competition, may...

This paper analyzes the strategic decision to integrate by firms that produce complementary products. Integration entails bundling pricing. We find out that integration is privately profitable for a high enough degree of product differentiation, that profits of the non-integrated firms decrease,...

This paper reviews the Hotelling literature of product differentiation. The purpose of this work is to examine the impact of the market structure on price competitionand equilibrium differentiation. The existence of a general ’principle of differentiation’ is rejected. In contrast,...

This paper extends the standard Hotelling model with quadratic transport costs to the multi-firm case. Considering locational equilibria we show that neither holds the Principle of Maximum Differentiation - as in the duopoly model - nor does the Principle of Minimum Differentiation - as in the...

We demonstrate the sensitivity of the location of downstream firms, engaged in sequential spatial competition, to the vertical structure of an industry where no downstream firm can produce all varieties demanded.

Different structures of lignite mines and power stations, which have appeared on the Polish market as a result of its transformation and the privatisation, were discussed. The attention is focused on the fact that the practice is overtaking the theory because there is lack of models of...

For methods of the profit division in the bilateral monopoly of the mine and the power station sug-gested in the first part of this paper the formulae for lignite price and shares in the joint profit of the mine and the power station are calculated. The proposed profit division contain: the...
