The growth of Chinese exports in market share over the past two decades is a singular event in the history of world trade. Using data from 1995–2010, we document this growth in a variety of ways. We show that the expanded trade is pervasive. Virtually every country in the world has seen China...

This paper examines the accumulation of physical capital versus knowledge (R&D) capital as a determinant of advanced countries’ comparative advantage. I show that advanced countries are abundant in R&D resources, specialize in knowledge-intensive stages of high-technology industries, and...

tried to resuscitate HOV by introducing a simple Hicks-neutral (HN) factor-productivity adjustment. In this paper, we re-examine this question by estimating factor-specific productivities from the individual technology data of multiple developed and developing countries. We find evidence of...

This paper explores a novel way to evaluate the extent to which R&D knowledge embodied in intermediate inputs correlates with productivity at the industry level. We propose the concept of the R&D content of intermediates, which represents the knowledge stock embodied in the intermediate inputs...

Understanding international differences in the emissions intensity of trade and production is essential to understanding the effects of greenhouse gas limitation policies. We develop data on emissions from 41 industrial sectors in 39 countries and estimate the CO2 emissions intensity of...

This paper examines how production techniques differ across countries, factors, and industries and considers its implications for previous empirical evidence on the Vanek prediction. I find that production techniques differ substantially across countries and factors, but differ much less across...
