In a three-stage duopoly game with product design at stage 1, advertising & marketing at stage 2, and price competition at stage 3, advertising & marketing enable customers to distinguish the goods from each other thus relaxing price competition. The subgame perfect equilibria of the three stage...

We consider a number of individual, discrete consumers, deciding their location on Hotelling's line in a non-cooperative way. Agglomeration emerges as a non-cooperative equilibrium, implying high transportation costs. No restriction is required concerning the functional forrn of transport costs...

A one-dimensional model of spatial political competition with endogenous party formation is developed. It is proved that at equilibrium there are only two parties. These parties propose alternatives in the extreme position s of the policy space. The adopted policy, however, is a compromise...

Two retailers operate in a monopsonistic, oligopolistic environment. They have to buy from spatially dispersed suppliers and use uniform pricing downstream. We characterize prices and location in the two-stage location-then-price game under two different pricing policies in the upstream market:...

A one-dimensional model of spatial political competition with incomplete information is developed.It is assumed that voters care about the distribu-tion of votes among the two candidates. Votershave an incomplete infor-mation about the distribution of voters´ types. We provide conditions...

Based on the assumption that location is especially relevant in the lodging industry, we exploit a dataset of Spanish hotels to examine the relationship between spatial competition and retail price level and dispersion. Our results support the hypothesis that a greater density of competitors...

I analyze the implications of bundling on price competition in a market with complementary products. Using a model of imperfect competition with product differentiation, I identify the incentives to bundle for two types of demand functions and study how they change with the size of the bundle....

I show the uniqueness of equilibrium for a class of oligopoly models with strategic complements.Product differentiation models are considered in which the contraction mapping theorem cannotnecessarily be applied.

In this paper we get the optimal two-part tariff contract for the licensing of a cost reducing innovation to a differentiated goods industry of a general size. We analyze the cases where the patentee is an independent laboratory or an incumbent firm. We show that, regardless of the number of...

In models of product differentiation and location models it is implicitly assumed that consumers can afford to buy the differentiated goods in the market. I show that with income heterogeneity there are severe existence problems of a price equilibrium in models of horizontal product...
