This paper presents a model of oligopolistic competition in presence of horizontal differentiation of goods, under a triangular distribution of consumers. The triangular distribution represents a case of concentration of consumers around the central location. The main result is that a good deal...

A two period R&D symmetric Cournot duopoly game with linear demand and costs is analysed under linear (or more general) returns to scale in process R&D. Subgame-perfect equilibrium may call for one firm to fully innovate while the other firm remains just as before. The outcome is a polar duopoly...

In this paper we consider a two-stage duopoly game where firms first decide whether to invest in advertising and then compete in prices. Advertising has two effects: a market enlargement for both firms and a predatory gain for the investing firm only. Both symmetric and asymmetric equilibria may...

Previous theoretical researches show that learning from good performers yields intense competition and results in the low profitability of firms. These researchers do not take into account differentiation strategies being referred as a useful strategic tool to mitigate competition. We introduce...

In this paper the standard Hotelling model with quadratic transport costs is extended to the multi-firm case. The sequential game consists of a location choice stage and a price setting stage. Considering locational equilibria it is shown that neither holds the Principle of Maximum...

We analyze firms' location choices in a Hotelling model with two-dimensional consumer heterogeneity, along addresses and transport cost parameters (flexibility). Firms can price discriminate based on perfect data on consumer addresses and (possibly) imperfect data on consumer flexibility. We...

The paper models duopolistic competition in so called monotowns: towns with one big factory where most of the citizens are employed. Workers after job go to one of the competitor shops, buy the product and bring it home. Nash equilibrium is found for linear and two-dimensional cases. The...

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...

The theory of geographical markets is based on the notion that economic activity is not evenly spread and regional inequalities have an impact on the decisions of economic agents. Retail gasoline markets are almost perfect examples of geographical markets. The gasoline sold by the stations is a...
