"“The cozy friendship between Epstein and Summers on display in the emails is disgusting and disgraceful,” Statistics professor Joseph K. Blitzstein, who teaches Harvard’s largest introductory statistics course, wrote in a statement to The Crimson."

As always, nice reporting from the Crimson here
While Summers has broken no laws, and he’s free to correspond with whom he chooses, there’s a lot here to support the idea that he should not be taken as an authoritative spokesman on so many important issues

Portable mortgages are like your cell phone plan: when you upgrade the phone, the plan comes with you. Let your mortgage follow you to the next house. That unfreezes movers—especially downsizers—and unlocks inventory.

Very sad about Ron passing away. One of the most stimulating econometricians I have come across during my career. A very fine scientist, always pushing areas he was interested in to the highest standards, not following the crowd. A wonderful person to spend time with.
It is with great sadness that I report the passing of Ron Gallant, a gifted econometrician. This Penn State page (there's also Duke and NC among his employers) links to his individual website. econ.la.psu.edu/people/arg21/

This seems very interesting. I would be keen to hear about experiences with Refine.

#econtwitter #econsky: recently used Refine.ink (developed by @ben_golub) as a AI assessment tool for papers + it is amazing, so wanted to share some examples of what it can do if you are curious. (It's much, much better than other free tools I've used)

There are accusations of impropriety against Lisa Cook, a fine economist, once again. Last time (around her confirmation as a Fed Board Governor) the specifics were public and obviously nonsense. This time, they may be buried in lawfare for a while. I stand with Lisa D. Cook.

Assume: 2% inflation, 2% real wage rises, 9% returns. An institution can spend 5% a year on employing the same number of folk each year for ever.
If returns are taxed at 21%, net returns become 7.1%. Can then spend 3.1% a year.
Tax reduces spend from 5% to 3.1%: about a 40% fall.
