Existing estimates of power laws in firm size typically ignore the impact of international trade. Using a simple theoretical framework, we show that international trade systematically affects the distribution of firm size: the power law exponent among exporting firms should be strictly lower in...

It has been suggested that countries whose exports are in especially risky sectors will experience higher output volatility. This paper develops a measure of the riskiness of a country's pattern of export specialization, and illustrates its features across countries and over time. The exercise...

This paper evaluates the global welfare impact of ChinaÕs trade integration and technological change in a quantitative Ricardian-Heckscher-Ohlin model implemented on 75 countries. We simulate two alternative productivity growth scenarios: a ÒbalancedÓ one in which ChinaÕs productivity grows...

This paper examines the impact of international trade on business cycle comovement using a unique dataset of sectoral output and trade flows. While the earlier studies employing aggregate data are certainly useful in understanding the broad impact of trade linkages on the transmission of...

This paper evaluates the global welfare impact of China's trade integration and technological change in a quantitative Ricardian-Heckscher-Ohlin model implemented on 75 countries. We simulate two alternative productivity growth scenarios: a balanced" one in which China's productivity grows at...

This paper proposes a new mechanism by which country size and international trade affect macroeconomic volatility. We study a model with heterogeneous firms that are subject to idiosyncratic firm-specific shocks, calibrated to data for the 50 largest economies in the world. When the firm size...

Countries that trade more with each other exhibit higher business cycle correlation. This paper examines the mechanisms underlying this relationship using a large cross-country, industry-level panel dataset of manufacturing production and trade. We show that sector pairs that experience more...

This paper investigates the role of individual firms in international business cycle comovement using data covering the universe of French firm-level value added, bilateral imports and exports, and cross-border ownership over the period 1993-2007. At the micro level, controlling for firm and...
