In the post-war period, the goods composition of trade in OECD countries has changed considerably. We analyze the evolution of comparative advantage using a detailed trade data set and a new analytical tool: the harmonic (weighted) mass index, which enables us to identify periods of structural...

This document describes and discusses a new supply side framework that quantifies the impact of structural reforms on per capita income in OECD countries. It presents the overall macroeconomic impacts of reforms by aggregating over the effects on physical capital, employment and productivity...

This paper uses an oligopoly model with heterogeneous firms to examine how an industry adjusts to rising import competition. The model predicts that in the short run the least efficient firms in the industry become inactive, surviving firms face a fall in output, mark-ups and profits, and the...

The European sovereign debt crisis revived the discussion concerning the pros and cons of exchange rate adjustment in the face of asymmetric shocks. Exit from the euro area is to regain rapidly international competitiveness. Exchange rate stability with structural reforms could be beneficial for...

This paper develops a two-sector R&D-based growth model with congestion effects from increasing urban population density. We show that endogenous technological progress causes structural change if there are positive productivity spillovers from the modern to the traditional sector and Engel's...

There is growing interest in multi-sector models that combine aggregate balanced growth, consistent with the well-known Kaldor facts, with systematic changes in the sectoral allocation of resources, consistent with the Kuznets facts. Although variations in the income elasticity of demand across...

Migration and trade are often linked through ethnic networks boosting bilateral trade. This study uses migration to quantify the importance of Ricardian technology differences for international trade. The framework provides the first panel estimates connecting country-industry productivity and...

We show that in a Ricardo-Viner-type trade model with unemployment due to search and matching the productivity effect of offshoring emphasized by Grossman & Rossi-Hansberg (2008) emerges as a vehicle of job creation. Improvements in the technology of offshoring causes job losses at the extensive...

In this paper, we merge the heterogenous firm trade model of Melitz (2003) with the Ricardian model of Dornbusch, Fisher and Samuelson (DFS 1977) to explain how the pattern of international specialization and trade is determined by the interaction of comparative advantage, economies of scale,...
