I found a point celebrating Thomas Schelling.

Surprisingly, I did not encounter any other fans of his work who had organically arrived there without any coordination.

Hi #econtwitter (#econtooter?) help requested:

I have an outcome y ~ x + x^2

I have a panel of units receiving a binary treatment at different time periods, x varies by unit & time

What I want to do is compare the betas on my x's by treatment status, to test whether treatment affects response to x

I'm familiar(ish) with DiD heterogeneity for fixed pre-treatment covariates, but here x is time varying & I'm worried about the coeffs for x, rather than the ATT

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.

I'm actually kinda surprised at the lack of econs tinkering with #fediverse instances. The discipline of decentralized equilibria + this platform? This ought to be a great lab for us to try new things!

Weitzman's 1974 "Prices vs Quantities" is another example of a broken symmetry in economics
https://scholar.harvard.edu/weitzman/files/prices_vs_quantities.pdf

In a standard model, a tax is equivalent to a quota: pick Q*, get P* or pick P* and get Q*. Weitzman (1974) shows this breaks when firms learn marginal costs and choose production levels after the regulator picks P* or Q*

In the standard model, payoffs are "conserved"; Weitzman's learning assumption breaks this conservation

IO/GMM/metrics question I don't really know how to phrase:

In grad IO I learned that BLP-type estimators have many solutions bc very nonlinear, so you solve from many starting points and take whatever solution has the lowest GMM objective fn value.

The process somehow feels, idk, unprincipled to me. Feels like there ought to be some more structured (Bayes? Dynamics? CV?) way to use info/find good solns.

1. Is this in my head?
2. If no what's the "structured" thing?
