We analyze models of product differentiation with perfect price discrimination and free entry. Although perfect price discrimination ensures efficient output decisions given product characteristics, coordination failures may prevent efficiency in the choice of product characteristics. More...

Comparative advertising by one brand against another showcases its merits versus the demerits of the other. In a two-stage game among finitely many firms, firms decide first how much to advertise against whom. In the second stage, given the advertising configuration, firms compete as Cournot...

A monopoly selling in two countries can use exclusive or competitive retailers to distribute its product. A low wholesale price in one country might induce a retailer to resell the good for profit in the other country, generating thereby parallel imports which compete with the authorized sales....

We analyze the effects of a legally-binding price floor using Hotelling's model of locational competition. A moderate price-floor destroys the maximal differentiation equilibrium of d'Aspremont et. al., by allowing firms to compete more aggressively for market share. Minimum differentiation...

Comparative advertising by one brand against another showcases its merits versus the demerits of the other. In a two-stage game among finitely many firms, firms decide first how much to advertise against whom. In the second stage, given the advertising configuration, firms compete as Cournot...

This paper analyzes the incentives for governments to impose export subsidies when firms invest in a cost saving technology before market competition. Governments first impose an export subsidy or a tax. After observing export policy, firms invest in cost reducing R&D and subsequently compete in...

We empirically test some implications from location theory using the location of Los Angeles area gasoline stations in physical space and in the space of product attributes. We consider the effect of demand patterns, entry costs, and several proxies for competition -- the total number of...

We study the effect of market structure upon international trade policy when firms invest in process R&D before competing in a differentiated goods market. For a domestic monopoly, and increasing the number of foreign firms, the government either chooses a R&D (and output) subsidy, or remains...

Platform sharing across manufacturers has recently become common practice in the automobile industry. Its important objective is to reduce procurement costs by taking advantage of the commonality of components, but this often reduces the degree of product differentiation. We investigate this...

The current overview of bundling theory is combined with author's experiences of its practical application into several step-by-step guidelines. These models consist of the whole process of the construction and performance appraisal of product bundles in retail banking sector and show how the...
