🔥🔥🔥Are you pissed about Armin Falk heading IZA? If yes, consider reading/sharing/signing this letter. To be clear I didn’t organize this letter, and I’m so pleased that instead of me it was more senior economists (some male) who stepped up to help with this effort. docs.google.com/document/d/1...

One for the JMCs: what are the alternatives to an academic job? Also, your job mobility does not end after the PhD, so you are not stuck with your initial placement if you don’t like it!

The more you get to know a concept the more subtle it appears to you and the more approximate and incomplete everyone else’s casual use of the concept starts to appear.

See as an empiricist I tend to think many economists misunderstand what OLS does. On the other hand, I think I have a good understanding of Nash Equilibrium. You, however, as a theorist think that most people don’t properly understand NE but you think they do understand OLS.

What counts as a correct understanding of OLS??

Especially when going from a single binary treatment to multiple or continuous treatments

Never assume that because you know a proposition is true in a simple case (e.g. regression beta = ATE with unconfoundedness & saturated model & constant TE, LATE theorem with binary D and Z, DiD with 2 periods = TWFE…) that it is true in general, when relaxing any of these assumptions.
