Technical Improvements and Welfare under International Duopoly

Masayuki Okawa

Review of International Economics, 2009, vol. 17, issue 5, 1001-1008

Abstract: It is now common wisdom that a free‐trading country with perfectly competitive markets might be hurt by its own technical improvement of that country's export industry, and that an improvement in the import‐competing industry never impoverishes the country if no commodity is inferior for that country. This paper examines the welfare effects of technical progress in a perfectly competitive industry and in an internationally duopolistic market in a two‐country, two‐good, one‐factor trading model. It will be shown that the above propositions are severely qualified in our setting with duopolistic industry.
