Is the variation in bilateral trade flows across countries primarily due to differences in the number of exporting firms (the extensive margin) or in the average size of an exporter (the intensive margin)? And how does this affect the estimation and quantitative implications of the Melitz (2003)...

Recent disruptions to global value chains (GVCs) have raised an important question: Can decoupling from GVCs increase a country’s welfare by reducing its exposure to foreign supply shocks? We use a quantitative trade model to simulate GVCs decoupling, defined as increased barriers to global...

This paper analyzes the initial impact and recovery of globally engaged firms from the COVID-19 crisis. It uses rich survey data of nearly 65,000 firm-year observations in 45 countries spanning three waves of data collection. The findings are organized in a series of stylized facts, which...

We estimate the short-run trade effects of natural disasters using monthly trade data and data on the physical intensity of earthquakes and storms. We find large negative effects for heavily indebted poor, least developed or landlocked developing countries but only small effects for other...

In early 2020, the disease Covid-19 caused a drastic lockdown of the Chinese economy. We use a quantitative trade model with input-output linkages to gauge the effects of this adverse supply shock in China on the global economy through international trade and global value chains (GVCs). We find...

The past decades witnessed big changes in international trade with the rise of global value chains. Some countries, such as China, Poland, and Vietnam rode the tide, while other countries, many in the Africa region, faltered. This paper studies the determinants of participation in global value...
