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.

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.

"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.

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.
