W. Arthur Lewis argued that a new international economic order emerged between 1870 and 1913, and that global terms of trade forces produced rising primary product specialization and de-industrialization in the poor periphery. More recently, modern economists argue that volatility reduces growth...

This paper shows that greater global spatial correlation of productivities can increase cross-country welfare dispersion by increasing the correlation between a country's productivity and its gains from trade. We causally validate this prediction using a global climatic phenomenon as a natural...

We study the distribution of economic activity, as proxied by lights at night, across 250,000 grid cells of average area 560 square kilometers. We first document that nearly half of the variation can be explained by a parsimonious set of physical geography attributes. A full set of country...

In the wake of the U.S.-Canada Free Trade Agreement, both the U.S. and Canada experienced a sustained increase in job reallocation, including firms moving into exporting. The change involved big firms as much as small firms. To mimic these patterns,we formulate a model of innovation by both...

A persistent issue in environmental economics is whether growth is sustainable. Pollution is a key driver of sustainability, which we define as an economy exhibiting falling pollution damages at its balanced growth path. We deduct air pollution and carbon dioxide damages from the national...

We reconsider the empirical links between volatility and growth between 1970 and 2007. There is a strong and significant correlation between individual country growth rates and global factors that are arguably exogenous with respect to their economies. The amount of volatility driven by these...
