Extraordinary estimates of the impact of Chinese development finance, forthcoming in AEJ Policy. So large I struggle to believe them. Is Chinese dev finance very different from others, or should this move our beliefs about development finance in general?

This new paper in economic history by Tianyi Wang (PhD Pitt; postdoc Copenhagen) is timely and timeless. He uses variation in a racist populist show caused by topological factors to estimate the effect of the show on voteshare, as well as increase pro-Nazi groups. 1/n

Thx @jenniferdoleac! In my JMP, inspired by a 1920 USDA report of a similar title, I create a new dataset of women linked across censuses to show how gender segregation in farming, and the problems caused by it, led to an exodus of women during the 1920-1940 US farm crisis. (1/7)

Interesting threads/discussions
Steven Hamilton@SHamiltonian
The switch from stamp duty (housing transaction tax) to land tax is often framed as a no-brainer. But there’s an underdiscussed trade-off that goes to the heart of a key issue in optimal taxation, which itself has been understudied. A wonkish thread. 1/10

This should never happen, what a waste of everyone’s time and energy.
If it got this far in the process, publish it and let the scientific community decide how to interpret it.
Published papers don’t have to be right (most aren’t)— they just have to be worth thinking about.

A paper rejection after two rounds of R&R hurts.

@causalinf @imbernomics @nberpubs i think the better way to view it is as a big reading group / conference that got started in the 80s by some powerful people and slowly took over the profession -- the starting tastes and preferences in the 80s had a big influence.

Nick HK@nickchk
If you look at autocorrelated data, pick any random day, and look for a break in linear trend on that day, you will find a statistically significant break a ludicrous amount of the time. In this random AR(1) data with delta = .8, I reject the null at 95% about half the time.

Kim Border was an extraordinarily generous person, an encyclopedic store of knowledge, and an amazing producer of public goods. One of my first economics teachers.
I'll use this thread to share a few favorite examples of his writings. I hope some others do as well.

I'm saddened to learn that Kim Border passed away yesterday. Kim was a Caltech professor for 41 years. A passionate teacher of mathematical economics, author of amazing books & notes, and a deeply kind soul. I'm so grateful for the time I got to spend with him.
