This paper reviews the most significant recent developments in the theory of trade agreements. The paper offers an integrated approach to evaluating trade agreements, and uses the approach to present results on preferential and multilateral trade agreements. The paper identifies also several...

When national competitiveness is invoked as a policy objective, trade experts have learned to retort that countries don't trade, firms do. This focus on the importance of the firm in international trade is consistent with the most recent developments in trade theory, but policy needs to catch...

This paper theoretically and empirically investigates the relationship between the number of product varieties and the extent of intra-industry trade (IIT). IIT provides more trade opportunities for countries in which differentiated products are produced. The model presented shows that the...

The conventional wisdom is there have been two globalizations in the modern era. The first began around 1870 and ended in 1914. The second began in 1945 and is still underway. This paper challenges that view and argues there have been three globalizations, not two. The first half of the paper...

This paper develops a multi-country, general equilibrium, semi endogenous growth model of innovation and trade in which specialization in innovation and production are jointly determined. The distinctive element of the model is the ability of the agents to direct their research efforts to...

Samuelson extends the Ricardian theory of foreign trade to a model of small open economies in which countries can trade semi-finished capital goods on international markets, as well as produced consumer goods. He argues that this extension provides an additional gain from trade, which he labels...

A deranged publisher decided to produce a volume of some of my papers and asked me to write some comments. Since these amount to a summary of my views about international trade theory over the latest forty years or so, I'm giving the comments a separate alternative existence as a discussion paper

This article presents an applied general equilibrium model which combines the theoretical foundations of an Eaton-Kortum type model of international trade with the complexity of a global multi-region, multi-sector Computable General Equilibrium (CGE) model of production and consumption. The...
