We investigate and compare countries' export growth based on their performance at the extensive and intensive export margins. Our empirical approach is motivated by an extension to the Melitz (2003) model of heterogeneous firms in which exporters are subject to a one-time sunk cost and also a...

We use a new firm level data set that establishes the location, ownership, and activity of 650,000 multinational subsidiaries -- close to a comprehensive picture of global multinational activity. A number of patterns emerge from the data. Most foreign direct investment (FDI) occurs between rich...

The Linder hypothesis states that countries of similar income per capita should trade more intensely with one another. This hypothesis has attracted substantial research over decades, but the empirical evidence has failed to provide consistent support for it. This paper shows that the reason for...

This essay surveys the evidence on the linkages between globalization and poverty. I focus on two measures of globalization: trade and international capital flows. Past researchers have argued that global economic integration should help the poor since poor countries have a comparative advantage...

Common wisdom dictates that uncertainty impedes trade—we show that uncertainty can fuel more trade in a simple general equilibrium trade model with information frictions. In equilibrium, increases in uncertainty increase both the mean and the variance in returns to exporting implying that...

We combine data on trade, production, and input use to document changes in the value added content of trade between 1970 and 2009. The ratio of value-added to gross exports fell by roughly 10 percentage points worldwide. The ratio declined 20 percentage points in manufacturing, but rose in...

This paper highlights the rare conditions leading to international cooperation, and the reasons why eliciting this cooperation may be beneficial in preventing adverse tail shocks from spiraling into global depressions. In normal times, deeper macro cooperation among countries is associated with...
