Abstract

Théoricien inventif et brillant, Paul Krugman est notamment le principal architecte des nouvelles théories du commerce international. L'introduction de la concurrence imparfaite dans ce corpus a permis de montrer que le commerce international pouvait émerger sans avantages comparatifs, et de comprendre les motivations et les implications des échanges intra-branches entre pays similaires. Surtout, les analyses de Paul Krugman ont définitivement rapproché les théories du commerce des analyses de l'économie géographique, ce qui a modifié en profondeur notre vision de la mondialisation. Creative and talented theorist, Paul Krugman is the main architect of the new theories of international trade. He has shown that international trade can emerge without comparative advantages, in an imperfectly competitive environment. His models have provided convincing explanations to intra-industry trade between similar countries. Even more importantly, Paul Krugman has definitively bridged trade theories to economic geography, which deeply changed our views on globalization.
