The Rogoff/Yang 'Peak China Housing' paper doesn't cover a huge amount of new ground but it's a nice summation of the case. Figure 16 is a personal favourite among the many horrifying China housing finance charts. nber.org/papers/w27697
Two trends shaped the 🌍 post-WWII: 1. Farmers became city dwellers -> More than 50% of pop now lives in a city 2. Global surge in formal education -> Average yrs of school doubled! In a new WP w/ & Santangelo we show that 2. contributed to 1. Thread 👇

Two pretty damning RD graphs for AEA's 'chart of the week' from new Sheetal Sekhri paper: aeaweb.org/research/chart… Getting into an elite college in India... 1. Doesn't improve your college exit-exam scores. 2. But does massively increase your salary.
What happens when you give literally every single child in a country a laptop? They use it for gaming, music, and it doesn't improve educational attainment. Among those who attened college they are more likely to choose health fields over art. papers.ccpr.ucla.edu/index.php/pwp/…
My JMP found a home! Thanks to my advisors, , Laura, and Venky for all their support. Short thread on the paper:

Out today is our paper on estimating causal effects on a network! This was joint work with twitterless Eric Tchetgen Tchetgen and Ilya Shpitser. This project occupied a significant portion of my PhD… and about 10% of my life… so enjoy! tandfonline.com/doi/full/10.10… 1/n
Seems like a rather important new paper on the supposed polarization of American jobs/wages (caused by tech, trade, etc). Middle wage workers are disappearing, BUT increasingly moving to high wage - not low wage - jobs. Especially women. nber.org/papers/w26064.…
Good threads that should be blogposts
A few thoughts on working in policy research as an Economics PhD. A thread that could be interesting for Econ JMCs in light of a shortage of academic jobs, but hopefully not just because of that. cc 1/n
Before this tweetstorm passes, a final cloudburst ⛈️⭢⛅ If you follow the research on how emigration rises with development, you might be asking: Wait, didn't I just see a paper finding the exact opposite? If so, this thread is for you. Step in ☞
Today and I are releasing results from our survey of econ RAs / pre-docs Summary slides here: z-y-huang.github.io/predoc_survey/… Full data appendix here: z-y-huang.github.io/predoc_survey/… A thread on some of our results 1/15
*A thread for upcoming first-year Econ PhD students* As the academic year is approaching, I would like to give brief advice based on my experience as a first-year PhD student who performed poorly in math camp and the first set of midterms but did better as the year progressed.
