Critical Evidence on Comparative Advantage? North‐North Trade in a Multilateral World
反驳了“比较优势无法解释相似经济体间大量贸易”的常见观点，论证了基于比较优势的理论同样可以解释北北贸易，并追溯了其技术和禀赋根源。
There are two principal theories of why countries trade: comparative advantage and increasing returns to scale. Which is most important in practice? The large volume of intra-OECD trade is frequently cited as critical evidence on this question. It is argued that comparative advantage, unlike scale economies, is incapable of accounting for the large volume of trade between seemingly similar economies. This is a theoretical claim. In this paper, the author shows that it is possible to give an account of this trade based on comparative advantage. The elements that may give rise to a large volume of North-North trade are traced to identifiable features of technology and endowments. Copyright 1997 by the University of Chicago.
