1/ Hi, my name is Isaac Martinez. I am a PhD student in Economics at the LSE, and I wanted to share something personal. On July 6, 2025, I suffered a stroke while I was finishing my PhD. It was completely unexpected and changed my life. #EconTwitter #EconJobMarket

The new version of our first year PhD Macroeconomics textbook is out. It is not polished yet but now all chapters are included. We hope it would be useful for the new semester.

I am really happy about this paper. Through the process of writing it, we learned something fundamental about the workhorse model of labor market frictions - not just discovering normative properties (which, of course, is important), but also finding out how to analyze them.
On-the-job search leads to overvaluation of jobs, especially at the top of the job ladder, resulting in excess vacancy creation in the canonical search and matching model, from Masao Fukui and @ToshiMukoyama

Interesting…I’m surprised at the low level of structural papers.

With great sadness, I announce the passing of my co-author and friend, Marcus Hagedorn. His acerbic wit was as sharp as the vision of Toni Kroos. He attacked big research questions like he tackled the mountains of Mallorca on his bike. He will be missed.

New paper with @BennyKleinman & @ElioNimier! - 4% of establishments relocate each year (FRA & US). - Using those relocations, we find that “location effects” explain only 2-5% of spatial wage disparities. Summary below!
Why are wages in Paris or NYC higher than in other cities? In a new WP with @PaulineCarry & @BennyKleinman , we decompose spatial disparities btw “location effects” and the local composition of workers and establishments. New data on firm mobility + double-mover design. 🧵⬇️

The real impact of DOGE isn't going to be seen in macroeconomic variables because pretending you've made massive savings is not the same thing as actually making massive savings. But a microeconomic lens yields the more important insight... (1 of 2)

The UK is ageing, but not everywhere in the country is ageing at the same rate. While major cities are getting younger, London bucks this trend, having aged at a similar rate to British small towns over the past decade. Learn more here ➡️ https://t.co/5iBXPITosE

Hourly wage progression is negatively associated with being a mother, being older, and having less education. Among low-income workers, family circumstances can place real constraints on people’s willingness or ability to change job or progress in work.
