🚨 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?

Michael Jenuwine’s job market paper measures the cost of inflation in sticky-price models by exploiting vintage, or the duration of price spell, as an observable. https://t.co/kcAIvAm2BJ

Eugenia Menaguale's (@emenaguale) job market paper studies how market power in technology-specific capital markets shapes the direction of firms' technology adoption and workers' specific human capital accumulation. https://t.co/RwsIYavvSC

Elena Aguilar’s (@tag_elena) job market paper studies location choices as a human capital investment. High-opportunity cities like New York offer superior learning environments but require paying high upfront housing costs. https://t.co/ysMrlbFpkL

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!

[Becker Friedman Institute for Economics @BeckerFriedman]

🏙️ 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. https://t.co/e1qPKfwMlX

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 https://t.co/9svyY1M0M5

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 https://t.co/hhIDdlNghB

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.

Caveat: the U.S. data come from the ACS...
— limited coverage of smaller counties
— truncation of the top of the wage distribution

So I’d expect the pattern to be even stronger with U.S. administrative data.

[Hugo Lhuillier @Hugo_Lhu]

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.

Long-story short:

Employers —and how workers reallocate across them— are crucial at explaining spatial wage disparities.

[Hugo Lhuillier @Hugo_Lhu]

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

I am looking for one or two pre-docs to work with me at HEC Paris on historical patent data. Hopefully an exciting opportunity to develop quantitative skills in a nice research environment. See the position here https://t.co/vtYZmenAq7

Thanks for sharing !

New version of "Outsourcing, Inequality and Aggregate Output" with @Hugo_Lhu. We characterize the equity-efficiency trade-off (rising inequality vs. efficiency gains) that comes with outsourcing domestic workers.

We have released new yearly measures of local GDP at the 1, 0.5, and 0.25 degree level. They are calculated using remote sensing data and a random forest model. All the data, documentation, and tests can be mapped and downloaded here: https://t.co/7uzq4rLXg5
