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.
💡 Why would a firm spend millions teaching workers it doesn’t even employ?
From open-sourcing to free certifications, superstar firms often train the workforce of their customers.
My JMP explains why. 🧵👇 1/n

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.
