The Structure of Foreign Trade
综述了过去二十年关于世界贸易结构的研究，涵盖理论创新和实证方法，特别是1980年代和1990年代在要素贸易内容、规模经济和产品差异化方面的进展，适合对国际贸易理论发展感兴趣的学者。
During the last two decades, new research has greatly advanced the understanding of the structure of world trade. While research in the 1960s and 1970s provided mostly theoretical insights, major empirical innovations concerning the study of factor content of net trade flows appeared in the 1980s. Important improvements in this line of research were added in the 1990s. The author also discusses the literature that emphasizes economies of scale and product differentiation. This work was done mostly in the 1980s and 1990s, yielding important theoretical and empirical findings. An emphasis on the interplay between theoretical and empirical research characterizes the entire presentation.
