Horiuchi and Ishikawa (2007) examine the relationship between tariffs on the final good and international technology transfer through trade in an intermediate good. They show that a decrease in the tariff as well as an increase may lead the North monopolist to transfer technology to a South potential entrant. This paper shows that tariff-reductions may induce technology transfer even if technologytransfer competition among multiple North firms is taken into account.

This paper sets out a single monopoly model and examines the effects of various trade policies on domestic, foreign and world economies under both segmented and integrated markets. In the segmented~markets case, the spillover effects which stem from non~constant marginal costs are explicitly dealt with. In the integrated-markets case, trade policies are examined in two different notions of market integration. It is shown that the curvature of demand curves are crucial for results and that trade restrictions taken by one country may benefit the other country and/or the world economy.
