Firms willing to enter a market with a new product often face the problem that the market does notknow its quality. Selling through a retailer might avoid excessive entry costs by renting thereputation of an incumbent. The incumbent can apply excusive dealing clauses to his retailer. Weshow that...

The model of the circular road has proved to be a popular model of oligopolistic interaction, yet its theoretical properties are not fully explored. In this paper I extend the uniqueness result of price equilibrium in the circular road with equidistant locations from quadratic transportation...

Evidence of the existence of overeducation in the Spanish labour market has drawn the attention of research on the transitory character of overeducation (Alba-Ramirez, 1993 and García and Malo, 1995). Our main interest lies on whether overeducation is a source of inefficiency in the allocation...

The paper formalizes the observation that submarkets for high-quality and low-quality variants are markedly different from each other. We study a simple model where variants of low quality cannot be horizontally differentiated, whereas customers disagree about the value of variants in the...

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...

Two one-product firms compete in prices on a market with differentiated products. Goods are differentiated because customers switch from one good to the other at different relative prices. With the specification that mean demand in the market is unit-elastic 1 pro vide conditions on the shape 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...

The analysis of the determinants of the individual wage income can be transfered to the total domestic income from the point of view of the human capital. This paper analyzes the effects that a group of variables, relative to sociodemographic and labour attributes, exerts on the total income...

This paper carries out a household classification in the framework of the Social Accounting Matrix. Bearing in mind the enlargeinent proposals of the National Accounts System of the United Nations, a first classification of Spanish households in accordance with certain demographic...

Models of product differentiation try to provide answers to the question which good will be provided in an imperfectly competitive market and how it will be priced. In such models consumers have been modeled as buying one unit of one good in the market. I construct counterparts to frequently...
