We examine the extent to which developing countries that do little, if any research and development themselves benefit from R&D that is performed in the industrial countries. By trading with an industrial country that has large 'stocks of knowledge' from its cumulative R&D activities, a...

This paper places current efforts at international economic policy coordination in historical perspective. It argues that successful cooperation is most likely in four sets of circumstances. First, when it centers on technical issues. Second, when cooperation is institutionalized - when...

This paper reviews a new framework for analyzing the interrelationship between inequality, unemployment, labor market frictions, and foreign trade. This framework emphasizes firm heterogeneity and search and matching frictions in labor markets. It implies that the opening of trade may raise...

We develop a framework for studying trade in vertically and horizontally differentiated products. In our model, consumers with heterogeneous incomes and tastes purchase a homogeneous good as well as making a discrete choice of quality and variety of a differentiated product. The distribution of...

We study a two-country two-sector model of international trade in which one sector produces homogeneous products while the other produces differentiated products. The differentiated-product industry has firm heterogeneity, monopolistic competition, search and matching in its labor market, and...

We develop a simple model of international trade with heterogeneous firms that is consistent with a number of stylized features of the data. In particular, the model predicts positive as well as zero trade flows across pairs of countries, and it allows the number of exporting firms to vary...

New developments in the world economy have triggered research designed to better understand the changes in trade and investment patterns, and the reorganization of production across national borders. Although traditional trade theory has much to offer in explaining parts of this puzzle, other...

We analyze the impact of China's growth on the exports of other Asian countries. Our innovation is to distinguish the increase in China's demand for imports from its increased penetration of export markets. Using the gravity model, we disaggregate among commodity types and account for the...

We present a North South model of international trade in which differentiated products are developed in the North. Sectors are populated by final-good producers who differ in productivity levels. Based on productivity and sectoral characteristics, firms decide whether to integrate into the...

We survey research on the relationship between technology and trade. We begin with the old literature, which treated the state of technology as exogenous and asked how changes in technology affect the trade pattern and welfare. Recent research has attempted to endogenize technological progress...
