The paper considers issues in recent research on macroeconomic equilibrium in centrally planned economies. I defend the explicit aggregative , macroeconomic approach in theory, institutional relationships and measurement. It has offered a fresh, coherent framework for analysis of many CPE...

We estimate productivities at the sector level for 72 countries and 5 decades, and examine how they evolve over time in both developed and developing countries. In both country groups, comparative advantage has become weaker: productivity grew systematically faster in sectors that were initially...

Quantitative results from a large class of structural gravity models of international trade depend critically on the elasticity of trade with respect to trade frictions. We develop a new simulated method of moments estimator to estimate this elasticity from disaggregate price and trade-flow data...

How does a country's productivity growth a¤ect worldwide real incomes through international trade? In this paper, we take this classic question to the data by measuring the spillover e¤ects of China's productivity growth. Our framework features traditional terms-of-trade e¤ects and new trade...

Trade is measured on a gross sales basis while GDP is measured on a net sales basis, i.e. value added. The rapid internationalisation of production in the last two decades has meant that gross trade flows are increasingly unrepresentative of the value added flows. This fact has important...

We develop a dynamic multi-country general equilibrium model to investigate forces acting on the global economy during the Great Recession and ensuing recovery. Our multi-sector framework accounts completely for countries' trade, investment, production, and GDPs in terms of different sets of...

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...

This paper studies the trade of China in the past 150 years, starting from the first opening of China after the Opium War. The main purpose of the paper is to identify what is (and was) China's 'normal' level of foreign trade, and how these levels changed under different trade regimes, from 1840...

The 1990's dealt a blow to traditional Heckscher-Ohlin analysis of the relationship between trade and income inequality, as it became clear that rising inequality in low- income countries and other features of the data were inconsistent with that model. As a result, economists moved away from...

In this paper I use a cross country data set to analyze the relationship between trade orientation, trade distortions and growth. I first develop a simple endogenous growth model that emphasizes the process of technological absorption in small developing countries. According to this model...
