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.

My JMP explains why. 🧵👇 1/n

Trade Wars, Economic Chaos, and Law: Unpacking Trump’s Trade Tactics with Alan Sykes | Stanford Law School

What’s happening with tariffs, why is there so much upheaval, and how do we get out of this?

SIEPR Senior Fellow Alan Sykes, an expert on the law and economics of international trade, joins Stanford Law School podcast Stanford Legal to break it all down.

New paper on "Geoeconomic Pressure" leverages LLMs to measure the effect of tariffs, export controls, and sanction on firms worldwide". We find a massive increase in 2025 Q1 in tariffs (thread follows)

Remembering Patrick L. Bajari (1969-2025) Patrick L. Bajari was a pioneer spanning the academic and business worlds.
