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...

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...

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...

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 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...

In this paper we argue that pricing is all about price changes, and that the costs of price changes are often simultaneously subtle and substantial. We discuss a framework to deal with the dynamics of changing prices. This framework incorporates customer interpretations of price changes, an...
