What tariffs would countries impose if they did not have to fear any retaliation? What would occur if there was a complete breakdown of trade policy cooperation? What would be the outcome if countries engaged in fully efficient trade negotiations? And what would happen to trade policy...

We analyze recent contributions to growth theory based on the model of expanding variety of Romer [Romer, P. (1990). “Endogenous technological change”. Journal of Political Economy 98, 71–102]. In the first part, we present different versions of the benchmark linear model with imperfect...

The 1990s produced a large literature on foreign trade and the environment, including both theoretical and empirical contributions. The paper surveys this literature. It starts by looking at the traditional Heckscher–Ohlin type models of international trade and then moves to noncompetitive...

In this chapter we present the main characteristics and problems involved in the study of the arms trade: product definition and data, strategic aspects of the arms trade and regulation. We illustrate these aspects using the latest theoretical and empirical literature on arms trade. The papers...

This chapter reviews the theoretical and empirical literature on learning by doing. Many of the distinctive theoretical implications of learning by doing have been derived under the assumption that the cost–quantity relationships observed in numerous empirical studies are largely the result of...

This chapter considers alternatives to the Armington formulation of international trade found in most computable general equilibrium (CGE) models. International trade structures consistent with the monopolistic competition models suggested by Krugman (1980) and Melitz (2003) are presented in a...

This chapter provides an overview of the first two decades of the Global Trade Analysis Project (GTAP) an effort to support a standardized database and computable general equilibrium (CGE) modeling platform for international economic analysis. It characterizes GTAP in four different dimensions:...
