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...

Two-stage game models of information acquisition in stochastic oligopolies require the unrealistic assumption that firms observe the precision of information chosen by their competitors before determining quantities. This paper analyzes secret information acquisition as a one-stage game....

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...

We study the product and process innovation choice of firms in which a managerial incentive à la Vickers (1985) is present. Taking a two-stage dynamic game approach, we show that managerial firms are led to over-invest in process innovation, as compared to standard profit-maximising firms,...

The paper extends the analysis of price competition among capacity-constrained sellers beyond the cases of duopoly and symmetric oligopoly.We first provide some general results for the oligopoly and then focus on the triopoly, providing a complete characterization of the mixed strategy...

This paper studies the identification of best response functions in binary games without making strong parametric assumptions about the payoffs. The best response function gives the utility maximizing response to a decision of the other players. This is analogous to the response function in the...

We extend Armstrong’s result on exclusion in multi-dimensional screening models in two key ways, providing support for the view that this result holds true in a large class of models and is applicable to many different markets. First, we relax the strong technical assumptions he imposed on...
