Wage Dispersion and Efficiency. It is often assumed that markets generate efficient allocations, but these are not necessarily fair. The widening of wage differentials that is currently observed is interpreted in this manner: Skill-biased technological progress increases demand for skilled work...

In this note we construct a simple international differentiated duopoly model that involves a divisionalization decision. It will be shown that the number of third market divisions of a parent firm with a cost advantage is relatively large. The results imply that the cost competitiveness of one...

This paper presents an ordered search model in which consumers search both for price and product fitness. We show that there is price dispersion in equilibrium and prices rise in the order of search. The top firms in consumer search order, though charge lower prices, earn higher profits due to...

The article examines a differentiated-products duopoly model where the firms make entry decisions to two markets and then choose prices. The effects of product differentiation and entry costs are analyzed in two games: with and without price discrimination between the markets. Allowing price...

Consumers often have to decide whether to go to a remote store for a lower price. Only the absolute price difference between the stores should be relevant in this case, but several experiments showed that people exhibit "relative thinking": they are affected also by the relative savings...

We study product differentiation on a Salop circle when firms relocate incrementally due to bounded rationality. We prove that, under common assumptions on demand, firms relocate only when two or more firms target the same niche. In any other case, there is no incentive for any firm to relocate...

We endogenize product differentiation in a model of sequential search with random firm-consumer match value à la Wolinsky (1986) and Anderson and Renault (1999). We focus on a product design choice by which a firm can control the dispersion of consumer valuations for its product; we interpret...

We analyse the dynamics of a Cournot duopoly game with heterogeneous players to investigate the effects of micro-founded differentiated products demand. The present analysis, which modifies and extends Zhang et al. (2007) (Zhang, J., Da, Q., Wang, Y., 2007. Analysis of nonlinear duopoly game...

This paper revisits the D-S (Dixit-Stiglitz) model. It’s a simple general monopolistic model with n monopolistic goods, and a numeraire good Labour ( w=1); aggregation for all goods in the economy. We have considered in our paper constant elasticity of substitution case(CES).On the supply...

The impact that competition exerts on the incentives of firms to pass through reductions in their marginal costs is an important consideration in assessing the performance of alternate market structures. This paper examines the role of product differentiation on firm-specific and industry-wide...
