New paper by @jondr44 & @pedrohcgs on how to estimate treatment effects w staggered rollouts.
Also provides updated estimates on the effect of procedural justice training for Chicago police--a PNAS study from the summer that I'd highlighted at the time.

I submitted my JMP so it’s finally time to do a thread! The paper asks why real wages have turned countercyclical and focuses on the causes and consequences of compositional shifts in the employed pool. I’ll start with a 4-point TL;DR summary, then get into details 👇

Using diff-diiff and RD, we found that administrative decentralization improves: school enrollment, student achievement, quality of teachers hired (measured by education level and scores on entry competency exams), and local resources investment in education.

In a blinded name-swap experiment, black female high school students were significantly less likely to be recommended for AP Calculus compared to other students with identical academic credentials. Important new paper from @DaniaFrancis:

Today is @ShengwuLi's birthday! An incredible coauthor! An excuse to write about our ECTA paper on "credible mechanisms."
There, we made a theoretical prediction that in the online world, real 2nd-price auctions can't survive! Google made the prediction official soon after: 1/N

Excited to announce my JMP came out *today* in AEJ:EP.
Much gratitude to Noto and a fleet of helpful people full of good advice. I've been bowled over by how generous people are.

Does immigration increase crime?
"we document null effects of immigration on crime but positive and significant effects on crime-related concerns"
Disproportionate news coverage of immigrant crimes plays a key role.

Interesting discussions

^👀, will we need a “best of econ Clubhouse” newsletter soon? See also: “Thinking about doing a Clubhouse session on Econ PhD in Tech”
Scarlet Chen@ScarletSijia
There's a stark difference in tech vs econ academia in terms of how a newbie ramp up / how a worker is managed
- in tech the manager/mentor spend a lot more time doing hands-on 'teaching'
- in econ (unless you're at MIT) it's much like 'drown you into the pool till you can swim'

In the past couple of weeks I've chatted more about my take-aways from my postdoc experience (without TT job lined up), and what I wish I had known when I accepted the job and when I started it.
🧵below.
Usual disclaimer. This is my personal experience. There's free disposal.

I think of research design (informally) as being fundamentally about whether you have a story for where your identifying variation comes from--contrasted with the case where your identifying variation is basically an unknown residual.

@VC31415 That what was so interesting!! I couldn't find one. The Angrist Pischke JEP symposium uses the term 69 times with no definition 😔
I tried to give a definition, but honestly this could use more work: https://t.co/AJdpeAkuMe
