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)...

This paper uses firm-level data on manufacturing trade from 40 developing countries to explore how the five largest exporters in a country contribute to export growth and diversification. The origins of these firms are also studied. The data show that the top five exporters account for on...

The Melitz model highlights the importance of the extensive margin (the number of firms exporting) for trade flows. Using the World Bank's Exporter Dynamics Database (EDD) featuring firm-level exports from 50 countries, we find that around 50% of variation in exports is along the extensive...

This paper studies the impact that import competition from China had on firms performance in the manufacturing sector in Peru in 2005-2015. Using a firm-level dataset that covers the universe of firms in the formal sector, our results reveal that Peruvian firms reacted to increased competition...

This paper studies the impact of import competition from China on informality and wages in the Peruvian manufacturing sector in 20012010. Using data from the Peruvian Household Survey, we use a two-step procedure to evaluate the impact of the surge in imports from China on the likelihood of...

The Venezuelan migration to Peru has been growing at fast speed since 2016 reaching a peak in 2018. Using a panel that allows us to control for individual effects, we study the heterogeneous short-term responses to the inflow of Venezuelan migrants in terms of employment, informality and...

We examine the effects of transit, documentation, and ports and customs delays on Africa's exports. We find that transit delays have the most economically and statically significant effect on exports. A one day reduction in inland travel times leads to a 7 percent increase in exports. Put...
