It's so funny when someone brags about a 4.5 GPA. The whole point of the GPA is it's out of 4, that's what makes it comparable and useful. If it's >4, we know your school is playing silly games with bonus points, but we have no idea what it's out of. 5? 10?

I don't know if this is persuasive or not, but I tell undergrads they should think of every economic regulation as starting with the word "If". IF you hire someone, you must pay them at least $X. IF you rent out an apartment, you can't charge more than $Y. Focuses the

They are not non existent. If your baby cries during the vows, their existence will be very much known. Child free means no children at all.

Not to start A Discourse but I was invited to a child-free wedding on the West Coast in January. It will be 3 wks after I have my baby. Does "child-free wedding" also include very young newborns? Curious about thoughts. Newborns (to my mind) are basically nonexistent.

Today, I joined 500+ researchers from 70 countries in calling on world leaders to create an International Panel on Inequality modelled after the IPCC— as recommended by the G20 Committee on Inequality led by @JosephEStiglitz. Help us spread the call. 🔗 https://t.co/R6mNpSUxMT

Almost certainly Seattle. Population went from 600k->800k, the city went from no rail system to a top-10 busiest network, region became an absolute economic powerhouse, there’s a total transformation of the waterfront, and so much more

So far: - 10% of students have disability accommodations, 2x the 2014 level - getting one of these raises your GPA by about 0.3 - They are disproportionately going to high-income, white, female students How do we interpret all this? It's not that easy, and sensitive. 9/

I am on the (red-hot) 2025–26 academic job market! I study wide-ranging, important, and contemporary issues in education policy and domestic violence. My job market paper studies academic accommodations in higher education: trends and drivers, who uses them, and academic impacts.

I am super excited to share a new AI tool, Refine. Refine thoroughly studies research papers like a referee and finds issues with correctness, clarity, and consistency. In my own papers, it regularly catches problems that my coauthors and I missed. 1/

Obesity is a leading cause of death and is associated with many more (eg cancer, diabetes). GLP-1 drugs have been a miracle for so many people, but were too expensive and out of reach for millions more. This is *incredible* news.

In Evanston yesterday, immigration agents went around with guns drawn, interrupting Halloween gatherings (my kid’s school moved theirs indoors), and pulling people from cars. Local police had to step in to separate agents from residents. This cannot become the new normal.

The 2020 Census was a fraud. The Biden admin used a shady “privacy” formula that scrambled the data and miscounted 14 states. It included illegal immigrants and handed Democrats extra seats. Americans deserve a fair count and I’m fighting to fix it.

I feel kind of bad singling out this post but this is *earnings*, not wages (!!) Why are labor economists so terrible about this distinction? Doesn’t matter for the pattern here but no normal human would make this mistake.

in spain, each successive male cohort earns lower wages than the previous one. in contrast, younger female cohorts at least reach parity with older generations as a result, the gender wage gap has decreased across cohorts, but mainly through men's relative decline
