Twitter shutting off its API to other apps without warning is unconscionable. Having never used the main Twitter app, it is impossible to replicate my use-flow that I had in Tweetbots. I now get why some people didn’t think moving to Mastodon was a problem.

Really cool paper in JUE this week. Say a nice new apartment opens up in your city, what happens?
I'll tell you two plausible stories, and this paper (along with a similar paper by @EvanMast2) can point us to which seems to be happening

Technological transitions are *slower* when skill specificity is *stronger* b/c it is driven less by the fast reallocation of older incumbent workers and more by the gradual entry of *younger* generations.
One insight from Adao, @MartinBeraja, and @nityanayar (2022).

Hi #EconTwitter, I’m an applied microeconomist and I'm in the #EconJobMarket
In my JMP I use machine learning to study gender attitudes in economic seminars.
A cited finding is that men interrupt women more than women interrupt men. I provide evidence disputing this #JMP 🧵

We exploit a discontinuity created by BOE's reserves constraint to assess impact of central bank credit rationing. Rationed counterparties had higher P(failure), but conditional on survival, they learned from their experience & changed behaviour during a subsequent crisis!

Investing money? Looking for a new job?
Often, we do not know the probabilities of potential outcomes (aka ambiguity).
Yet, we know much less about ambiguity attitudes, compared to risk attitudes.
New WP (joint with @econ_hmg and Axel Wogrolly) tries to change that 👇

Expanding insurance coverage for the treatment of certain diseases can reduce the associated mortality.

In Mexico, local violence leads to spillover effects beyond where violence occurs.
Key channel: student out-migration from violence-affected areas and peer exposure to violence.
In receiving schls, new peers exposed to local violence decreases incumbents’ academic performance

Cool to see papers on the 2014 Medicare expansion because it reminds me of a project I did on it sophomore year. It was just a regular DiD, I have to find it and see what the results are. It definitely wasn't robust because we definitely did not take into account selection effects when making it, but I guess that's what synthetic control models are for.
