We evaluate the sensitivity of the case for an R&D subsidy in an export sector when the outcome of R&D is uncertain and when the resulting product market is oligopolistic. Investments in R&D are assumed to induce either first order or mean-preserving second order shifts in the distribution of a...

Empirical studies have found that enhanced foreign competition can encourage or discourage innovation. To address this relationship, I examine a market structure in which a small number of large multi-product oligopolists compete with a large number of small single-product firms in the same...

Under GATT, countries are allowed to impose countervailing duties to offset foreign subsidies. However GATT rules limit the amount of duty to the amount of the subsidy. This paper examines a generalized model of imperfect competition with capital subsidies and shows the conditions under which a...

We develop a model of large multinational enterprises, each one producing a continuum of products. These outsized firms compete as oligopolists in a domestic and foreign market, facing competitive pressure from single-product firms that engage in monopolistic competition. The multinational...

We examine anticipatory product standards intended to improve the strategic position of firms in an international patent race where firms do R&D to develop products that are close substitutes. The effects of a standard are shown to depend on the way the standard is specified, which firm develops...

We augment the multi-market collusion model of Bernheim and Whinston (1990) by allowing for firm entry into, and exit from, individual markets. We show that this gives rise to a new mechanism by which a cartel can sustain a collusive agreement: Collusion at the extensive margin whereby firms...
