Accommodating emerging giants in the global economy History provides many examples of large changes in the relative economic size of nations. This column examines the impact of rapid economic growth in emerging economies on the income and welfare of other nations and the mechanisms through which these effects occur. The authors find that rapid growth in Chinese productivity from 1960 to 2020, and in Japanese productivity in the eary decades of the sample period, contributed to a decline in the US share of global GDP, but raised US welfare through reductions in consumer prices and the cost of living. The findings highlight that changes in...

Check out Eugenia’s brilliant paper on superstar firms and specialized skills! An important contribution to our understanding of growth and innovation in the technology sector.

Check out Yuyang’s terrific job market paper on evaluating the U.S. Interstate Highway Network in spatial equilibrium with decentralized strategic investments by state planners. A major advance in the knowledge frontier.

Excited to share my JMP “Strategic Transportation Investment and Coordinative Policies: Evidence from the U.S. Highway Network.” I show that limited cooperation across states leaves the U.S. highway network underbuilt and misallocated. I explain factors that drive these distortions. Link below.
