In a differentiated oligopoly with quantity as the strategic variable, an optimal tariff can lead to a welfare gain. When a quantity restraint is used instead, this gain can be offset, since the quota induces anticompetitive effects. However, alternative quantity restraints, such as import...

In this paper, we explore the issue of a simultaneous reduction in tariffs at different stages of a vertically-related market where each stage is oligopolistic. When vertically-related markets are characterized as a successive oligopoly, reducing tariffs by an equivalent amount on upstream and...

A model is developed to characterize the vertically linked and concentrated nature of developed-country food markets. This model is then parameterized and used to simulate the effects of varying food market structures on the benefits to developing-country exporters of agricultural commodities...

We consider the use of border adjustments to compensate exporters for domestic environmental taxes imposed on an intermediate good. A model of successive oligopoly is used to consider the appropriate border adjustments. In this set-up, the relative importance of the forward incidence of the...

In this paper, analysis is presented relating to the impact of border tax adjustments for climate policy on the problem of carbon leakage, and the related issue of competitiveness of energy-intensive industries. Compared to the current literature, these policies are set in the context of a...

In this paper, analysis is presented relating to the impact of border measures for climate policy on the problem of carbon leakage, and the related issue of competitiveness in the US aluminum industry, which can be characterized as oligopolistic. Specifically, it is shown that an appropriate...

This paper evaluates the trade policies introduced into the U.K. fertilizer market by the U.K. government and EC Commission in 1987. These policies are assessed in the context of theoretical developments in the analysis of trade policy where markets are imperfectly competitive. Specifically,...

Border tax adjustments for environmental taxes should leave imports of final goods unchanged. If intermediate and final goods markets are imperfectly competitive though, non-neutrality can result. Under Cournot behavior, an import tax equal to the environmental tax is too high, and under...
