This chapter (to appear in the forthcoming Handbook of International Economics, Vol. 5) develops a framework with which to interpret and survey answers to the question: how does increased openness affect aggregate welfare in a typical developing country? We decompose answers into four...

This paper discusses the likely evolution of the trade and environment issue in the World Trade Organization after the upcoming ministerial meeting in Singapore this December. It makes a number of points. Progress within the GATT/WTO on this issue looks likely to be slow and painfully...

This paper examines the political economy of U.S. trade policy around the time of the Smoot-Hawley tariff of 1930, a period when policy was unconstrained by trade agreements. We consider a model of politically-optimal trade policy for a large country that can influence its terms of trade and...

In this paper we explore the effect of trade policy on productivity and welfare in the now standard model of firm-level heterogeneity and product differentiation with monopolistic competition. To obtain sharp results, we restrict attention to an economy that takes as given the price of imports...

We illuminate the relationship between optimal firm pricing and optimal trade policy by exploring a generalized model that accommodates product differentiation at both the national and sub-national (firm) levels. We assume monopolistic competition in the differentiated products at the...

This paper uses three models of a small open economy to analyze the effects of terms of trade and exchange rate changes (i.e. devaluations) on labor market adjustment. First, a three goods (exportables, importables, non-tradables), four factors model is developed and used to investigate how an...

Concerns that (1) growth in developing countries could worsen the US terms of trade and (2) that increased US trade with developing countries will increase US wage inequality both implicitly reflect the assumption that goods produced in the United States and developing countries are close...

The national terms of trade, defined as the ratio of an export price index to an import price index has been extensively studied empirically. In this paper we construct an alternative measure, which we call the consumption terms of trade. This measure recognizes the fact that consumers and firms...

This paper analyzes the welfare implications of international spillovers related to productivity gains, changes in market size, or government spending. We introduce trade costs and endogenous varieties in a two-country general-equilibrium model with monopolistic competition, drawing a...

The contending fundamental determinants of growth -- institutions, geography and culture --exhibit far more persistence than do the growth rates they are supposed to explain. So, what exogenous shocks might account for the variance around those persistent fundamentals? The terms of trade seems...
