🚨 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. michaeljenuwine.com/files/papers/j…

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. eumena.github.io/files/em_jmp.p…

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. elena-aguilar.net

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? nber.org/papers/w34072 eml.berkeley.edu/~schoefer/scho…

Thank you @BeckerFriedman for this summary of my research on the root of local wage inequality!

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/incom…

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.

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

Long-story short: Employers —and how workers reallocate across them— are crucial at explaining spatial wage disparities. 🔗 If you want to know more: hugolhuillier.com/files/papers/l…

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 dropbox.com/scl/fi/3obf3vc… 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: bfidatastudio.org/project/local-…
