@Fabercore In the IPEDS/header file (hd2021, e.g.) there is a code, named opeid for each institution ID; The opeid with last two digits = “00” means this is the mother campus. All institution IDs with the same digits before the last 2 belong to the same multi-campus university.

When 4 (yes 4!) Nobel laureates in Economics come to your workplace and tell you how they started.

Another ordinary day at @handels_sse !

🧵A long pause in student debt payments during a high inflation period is like forgiveness since the debt value decreases in real terms. This is the classical effect of inflation on nominal debt. But there is something special about student debt that makes it quite regressive.

So happy to be involved in this great project with amazing coauthors :)

[David Thesmar @dthesmar]

Amazing what my coauthors can pull off. We think this is a very simple method that can be used to do robustness checks in structural estimation. We apply it to two classic finance models. happy to hear your thoughts

Tagging @MehranE6790 who is now on Twitter.

[Sarah Turner @turnersarahe]

How much will WH promised student loan forgiveness cost? Distributional implications? Basic questions. WH press release has no cost estimates. If legislated policy, CBO would score expenditure implications. Shouldn’t disclosure standards be at least as high for executive branch?

@toniwhited @sc_cath If the data moment lies on (or near) the flat region in one of these plots of m vs. p the “true” SMM doesn’t work either. m wouldn’t identify p…

1⃣ We propose a simple inexpensive approach to better understand structural models. We apply our method to illustrate identification, robustness to moment selection and model misspecification.

…they will not have to repay the marginal dollar, if they earn the same; e.g. more subsidized loans doesn’t induce better education & better outcome, which I know is indeed the case: https://t.co/fSgEzWvQmo

[Sylvain Catherine @sc_cath]

4⃣ How can we not anticipate the distortionary effects of such a policy? Student will be encouraged to take more debt since they will not have to repay the marginal dollar, and colleges will have an incentive to further increase tuition.
