A large share of cross-country differences in productivity is explained by differences in agricultural productivity. Using a combination of sub-national agricultural statistics and geospatial datasets on crop-specific potential yields, we study the main drivers of this variation from a...

This paper estimates agricultural total factor productivity (TFP) in 162 countries between 1991 and 2015 and aims to understand sources of cross-country variations in agricultural TFP levels and its growth rates. Two factors affecting agricultural TFP are analyzed in detail - imported...

This paper examines the impact of highway expansion on aggregate productivity growth andsectoral reallocation between cities in China. To do so, I construct a unique dataset ofbilateral transportation costs between Chinese cities, digitized highway network maps, andfirm-level census. I first...

This paper proposes a new index of sectoral labor distortion using employment and valueaddedshares. We show that this index is highly correlated with growth both crosssectionallyand over time. We also use it to compare the degree of distortion amongcountries and identify sectors where the...

Our answer: Not so well. We reached that conclusion after reviewing recent research on the role of technology as a source of economic fluctuations. The bulk of the evidence suggests a limited role for aggregate technology shocks, pointing instead to demand factors as the main force behind the...

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 analyzes the effects of product market reforms in the short and medium term across 10 regulated industries and 18 advanced economies for the period 1998-2013 using internationally comparable firm-level data based on Orbis. It provides four key insights. First, product market reforms...

This paper documents stylized facts on the process of structural transformation around the world and empirically analyzes its determinants using data on real value added by sector of economic activity (agriculture, manufacturing and services) for a panel of 168 countries over the period...

The enormous global demand for smartphones in recent years has created a new global tech cycle. In 2016 alone, global smartphone sales reached close to 1.5 billion, one for every fifth person on earth. In turn, this has engendered complex and evolving supply chains across Asia. We show that the...

Global merchandise trade expanded rapidly over the last 6 1/2 decades and its relationship with global income has seen ebbs and flows. This paper examines the shifts in this relationship using time series data over 1950-2014 and situates it in the current and longer term context. The...
