We study the procompetitive effects of trade policies against a foreign oligopoly in a model of vertical product differentiation. We show that a uniform tariff policy like the Most Favored Nation (MFN) clause is always welfare superior to free trade because of a pure rent-extraction effect....

Numerical simulation exercises to analyze the impacts of potential changes in non-tariff policies commonly use ad valorem equivalent tariff treatment even though estimated impacts using explicit model representation and ad valorem equivalent treatments will differ. The difficulty for modellers...
