We examine the optimal R&D subsidy/tax policy under a vertically differentiated duopoly. In a significant departure from the existing work, we consider the case of asymmetric costs of product R&D where there is a small technology gap between firms. In our analysis, the endogeneity of quality...

This paper discusses the timing and the optimal trade policy in the presence of oligopolisitic industries and free entry. Collie (1994) proved that an importing government should not commit a countervailing duty in response to a foreign export subsidy. We show that his main conclusion does not...

Introducing network externalities into a model of vertically differentiated products, Lambertini and Orsini (2001, 2003) analyze the implications of a monopolist’s quality choice for social optimum. Moreover, they examine how the network externality affects quality, quantity, price, and social...

This paper analyses whether laissez faire is superior to tariff protection in the long-run, provided that the government of an importing country cannot precommit to an ex ante optimal tariff rate. We consider the cases of perfectly competitive foreign exporters and a monopolistic foreign...

We apply a model of an environmentally differentiated duopoly to the analysis of environmental policy in the form of a subsidy/tax on consumers based on emission levels of products. More specifically, we consider environmental and welfare effects of subsidizing consumers who purchase...

The purpose of this paper is to analyze the optimal export policy in a two-stage game in which a domestic and a foreign firm compete in price and R&D investment. Under international Bertrand duopoly, an export subsidy directly promotes excess price competition, as delineated by Eaton and...

This paper analyzes the choice of import tariffs and production subsidies to provide optimal protection of domestic industry in the presence of oligopolistic competition, provided that there is a difference in costs between domestic and foreign firms. We show that the choice of optimal...

Employing an environmentally differentiated duopoly model, we analyze how emission standards affect imports, the environment, and social welfare. We show that a strict emission standard is not necessarily import-restrictive, whereas it may possibly degrade the environment. Furthermore, we...

Employing an environmentally-differentiated products model with heterogeneous consumers in terms of environmental consciousness, this paper examines the effect of a unilateral change in a home emission standard on the qualities of products, aggregate emissions, and welfare of both home and...
