Jane Austen used 'however' at the beginning of a sentence, and so can you.

Line graph showing cumulative state adoption of chiropractic boards over time

I'm John Fallon, a labor economist on the job market. My JMP uncovers something wild: when chiropractors got licensed in the early 1900s, medical boards responded by making it HARDER to become a doctor.

Why would competition lead to stricter regulations?

This is amazing. I need one of these (Ann Arbor area native living in Buckeye country)

This project was fueled by RAGE

RAGE whenever I read or heard about (another) abuse of power by faculty

RAGE whenever I was asked to discuss a paper about gender wage differentials that attributed gaps to "preferences" with no consideration of how "preferences" are formed

🚀 I'm on the #EconSky Job Market!

My JMP asks a classic question:
Do large, dominant firms foster or hinder innovation?

To study this, I turn to the Great Merger Wave (1895–1904), when >2,600 U.S. firms combined into corporate giants like U.S. Steel and DuPont.

A JMP 🧵👇 (1/13)

Econ of Ed (and other) friends: what are the best studies linking in-college interventions to labor market outcomes? Especially interested in those that improve outcomes via different mechanism than completion. E.g. if a college wants to improve earnings of grads, what should they do?

We do a “thankful turkey” each November where we add a new feather each day. My son’s entry today has me feeling some mixed emotions… as an educator (+) but as a proud Michigander (🤨)

Workplace romances between managers and subordinates boost earnings (+6 percent) but raise turnover and breakups cut pay (–18 percent), from David C. Macdonald, Jerry Montonen, and Emily E. Nix www.nber.org/papers/w34346

More people should be talking about this.

Grads on the go: why mobility complicates college accountability

Measuring a college's value? It's more complicated than you think. A new study co-authored by Upjohn Institute's @bradhershbein.bsky.social reveals how graduates mobility - and where they end up - can skew traditional college accountability metrics.

I had this exact same experience this morning. Same reporter as Heidi.

This is *not* normal.

I have spoken to the press on these issues for two decades. No government official has ever demanded to know my identity in order to give a comment on a story.

It was so nice to spend the day at Miami Econ yesterday! They have such a great crew there. Thanks again for having me, @riacton.bsky.social +1 for summer seminars - casual atmosphere, but serious conversations about improving our work

I don’t think people who do this substitution are drinking their coffee black…

UPDATE: The Indiana legislature announced that, across the state's public universities, it will immediately eliminate 75 programs, suspend/teach-out 101, and force 232 to consolidate or be eliminated. Not surprisingly, these closures disproportionately affect arts, humanities, and social science.

My department @miamiecon.bsky.social is hiring an instructor/VAP to teach introductory macroeconomics this upcoming year. Could be a good opportunity for new PhDs or advanced grad students who are interested in teaching-focused positions.

Apply ASAP if interested! #econsky

Let’s not send low-income students back to the ’80s — Harvard Gazette Financial aid red tape nearly derailed Susan Dynarski’s undergrad dreams. Now she sees decades of progress under threat.

The music was pretty good

But aid for low-income students was a lot worse

All NSF GRFPs to students choosing to attend Harvard in the Fall were just terminated

Parks and Rec was way ahead of its time

Can confirm that my NSF grant "How False Beliefs Form & How to Correct Them" was cancelled today because it is "not in alignment with current NSF priorities" Shocking that understanding how people are misled by false information is now a forbidden topic. Our work will continue but at a smaller scale
