I am thrilled to share my first publication, “Salary disclosure and individual effort: Evidence from the National Hockey League”, recently accepted at JEBO.
A 🧵 on how a sudden shift to pay transparency impacted the NHL labor market. #EconTwitter authors.elsevier.com/a/1ffUPc24a-eN8

Interestingly, on a team level, while there was virtually no correlation between team payroll and team performance in the season leading up to disclosure (1989-90), the two become immediately and permanently linked after disclosure, with higher-paying teams winning more games.

Using instrumental variables in your research? Teaching IV this semester? @b_m_stewart and I have a new paper for you: osf.io/preprints/soca…
We have 3 goals:
-clarify IV assumptions
-illustrate the fragility of IV
-help researchers w/ a checklist
(1/11)

Our discussion of IV assumptions aims to be both accessible and rigorous. We annotate and color-code all equations and graphically depict violations of assumptions when possible. Instruments in blue, treatments in green. (2/11)

^color coding: underrated

Our paper on human capital depreciation is finally forthcoming in the American Economic Review (joint work with @mikedinerstein and Constantine Yannelis). We show that human capital depreciates when skills are unused using data from teachers in Greece.

A paper I missed, seems under-appreciated: The much-discussed fall in interstate migration seems to be in large part a result of data issues, particularly changes in rates of real moves that aren't self-reported and of self-reported moves that aren't real. www2.census.gov/ces/wp/2016/CE…

Main result: greater access to firearms in the Black community reduced the rate of lynching in the Jim Crow South. In a context where you are excluded from the institutions of governance and public safety, where terrorism against you is condoned, the tools of self-defense matter

"tech firms hired one in seven newly minted PhDs [from ten leading economics graduate programmes in the US] in 2022, up from less than one in 20 in 2018"

^does the “Sources” footnote here imply they hand-collected this data themselves? (Was there a paper recently that did this same analysis?)
![Twitter avatar for @deaneckles](https://substackcdn.com/image/twitter_name/w_96/deaneckles.jpg)
Yes, tech companies are hiring econ PhDs, but I think this misses the bigger picture here: Quantitative social scientists of many stripes working at tech companies.
🧵
For example: I think Meta employs more political science PhDs than economics PhDs.
