This paper looks *fascinating*.
1. Predict which papers should be cited based on NLP.
2. Which predicted cites get omitted?
Answer: papers by women, by authors at mid-tier unis, papers not in top journals.
Female authors/eds omit fewer references.

one 3-hr car race with leaded fuel uses as much lead as an airport in a year, and car races raised blood lead rates for kids until lead fuel was banned. Implies v high social cost of leaded fuel, which is still used in planes.
Alex Hollingsworth @ajhollingsworth
8/N
But does this exposure matter? Yes. Yes it does.
We find that exposure increases the rates of elevated blood lead in children. https://t.co/Our7wBiCaC

With redistricting shenanigans in full swing, this seemed a good time to tweet about our forthcoming paper in J of Politics. We find that ruling parties systematically win a slender majority of seats in close state house elections where control of redistricting is at stake. (1/N)

Q: What preference relations can we reliably infer from school choice data?
While Gale-Shapley Deferred Acceptance has been popular for school assignment for its strategyproofness, there's huge evidence that students make "mistakes" (playing dominated strategies) in practice

This is a useful thread which happens very kind toward my own research. Thanks @Simon_Mongey and @adam_tooze. Let me take the opportunity to articulate one thought and I apologize in advance because I will oversimplify it.

Good discussion in the replies
John Horton@johnjhorton
Is there a good layman’s explanation/analogy of the envelope theorem? I feel like there is some everyday or physics example where the result would strike people as “obvious,” but I can’t come up with a good one

In thinking about this year's #EconJobMarket, one analogue is what happened during the 2008-09 financial crisis. A new memo by our AEA committee on the job market explores this: 1/7
