🚨 New working paper 🚨
In large cities, wages are higher. But so are inequalities. In fact, low-wage workers earn lower real earnings there.
Why? What drives spatial wage disparities? Why some workers work at lower real wages in large cities?

Following a great edition at Columbia last week (thanks to Don, Conor, & Hugo for excellent organization), I updated my web site with the history of past CUREs dating back to the first one (Milan, 2009).

🚨Understanding Migration Responses to Local Shocks
New version of paper with @borusyak and Brian Kovak!
1/6 Many papers find that local labor demand shocks have sizable effects on wages and employment, but surprisingly small or imprecise effects on local population.

We're hiring a project coordinator to work on a large-scale experiment studying labor market discrimination.
This is a project I'm very excited about, and we're looking for someone who can take charge and make it happen!

New paper:
"What Does Consulting Do?"
w/ Gert Bijnens, @simon_jaeger
Consulting is a storied but opaque industry.
Our VAT-based B2B data permit the 1st comprehensive study:
Which firms buy consulting?
What happens when they do?

Thank you @BeckerFriedman for this summary of my research on the root of local wage inequality!
🏙️ High-paying jobs cluster in big cities, raising wages but also inequality. Yet over time, all urban workers tend to benefit—thanks to steeper career ladders and stronger growth paths. Research from Saieh Family Fellow @Hugo_Lhu. ow.ly/Ry1250Wrwnu

When knowledge spillovers are local, firms may under-invest in geographic expansion. This is studied using a spatial growth model, and detailed data on US firms, from Craig A. Chikis, @BennyKleinman, and @MartaPrato nber.org/papers/w34010

Just how much US income inequality has increased and why it is growing is a topic of intense debate among economists. We spoke with Matthieu Gomez of @columbia_econ about what's really behind the rise in top incomes. #ResearchHighlight aeaweb.org/research/income-i…

My new paper (essay?) explores how labor market institutions may affect not just unemployment & wages...
-but also productivity & growth,
-especially in Europe (vs. the US).
-Potential channel: "dynamism."
Based on my talk and paper at the ECB Forum on Central Banking in Sintra.
Examining how labor market institutions and rigidities continue to shape European competitiveness and unemployment, from @Schoefer_B nber.org/papers/w33975
Following up on yesterday’s thread:
The motivating fact also holds in the US.
Below: the correlation between each city’s wage decile and city size.
In both France and the US, low-wage workers earn similar wages in small and large cities.
@mattyglesias @DonalWarde
Understanding the mechanisms behind spatial inequality matters! For instance: what happens when job mobility slows down?
Big places lose their comparative advantage...
⬇️ Productivity, wages, and the number of workers in large cities shrink
⬆️ Smaller cities expand
Long-story short:
Employers —and how workers reallocate across them— are crucial at explaining spatial wage disparities.
