We are super excited to put this out into the world with @Conor_A_Walsh and @sharatganapati.
It’s the result of a long effort to think about the origins of the urban-biased growth that has been reshaping our politics and society for the last 40 years.
A little thread 🧵

Turns out, the Business Services sector alone account for all urban-biased growth.
Business Services: Information, Finance, Management and Professional Services, Admin Services, and Real Estate.
Outside these industries wage growth was very balanced across space.

I am so happy that our paper on Career Spillovers inside firms is out on @RevEconStudies! It has been quite a journey since we started in 2015! Hopefully, this is just a first step of a broader agenda that we are working on.
Summary of the paper below.

Are you interested in running your own surveys to answer important questions? I often get asked to share best practices & advice. So I decided to write a comprehensive "how to" guide covering the complete survey process from beginning to end: scholar.harvard.edu/files/stantche…

Really wild paper from DeepMind: deepmind.com/blog/discoveri… ; consider multiplying two 3x3 matrices. Using inner products like you surely learned, you need to multiply 27 numbers (plus some addition, but * is much harder computationally than +, so ignore that). But 27 isn't best!

New NBER working paper with @jwswallace and @jasonlschwartz on Covid mortality: “Excess death rates for Republicans and Democrats during the COVID-19 pandemic” nber.org/papers/w30512
Ungated on arxiv here: arxiv.org/abs/2209.10751
Thread 🧵1/
![Political affiliation has emerged as a potential risk factor for COVID-19, amid evidence that Republican-leaning counties have had higher COVID-19 death rates than Democrat-leaning counties and evidence of a link between political party affiliation and vaccination views. This study constructs an individual-level dataset with political affiliation and excess death rates during the COVID-19 pandemic via a linkage of 2017 voter registration in Ohio and Florida to mortality data from 2018 to 2021. We estimate substantially higher excess death rates for registered Republicans when compared to registered Democrats, with almost all of the difference concentrated in the period after vaccines were widely available in our study states. Overall, the excess death rate for Republicans was 5.4 percentage points (pp), or 76%, higher than the excess death rate for Democrats. Post-vaccines, the excess death rate gap between Republicans and Democrats widened from 1.6 pp (22% of the Democrat excess death](https://substackcdn.com/image/fetch/w_600,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fpbs.substack.com%2Fmedia%2FFeI-vIBXoAALwdS.png)

Thread. We build on our work on gender diffs in selection of Econometric Society Fellows. People asked us: is econ special? Eg, compare to a social sci w/ more females, psych, and to a science w/ underepresentstion of females like econ, math. How to compare apple to apple? (1/6)
