"Student lending was once profitable for the federal government. Now it loses 25 cents on every dollar lent. All told, officials expect their student-loan portfolio to cost around $450bn in the next nine years." my latest for @TheEconomist
If there is a glimmer of hope for America’s student-debt problem, it may lie in—of all places—Donald Trump’s free-spending “Big Beautiful Bill” econ.st/4lwpylp
Market-beating stock strategies don’t last, suggests research by Chicago Booth PhD student @benmarrow and Booth’s @ProfStefanNagel. ms.spr.ly/6018SIqgo

since I've picked up some new followers lately, here's a plug for my ~monthly blog of random things I learn benmarrow.substack.com/p/things-i-lea…
I wrote some words on the state of economics for @TheEconomist, graph below and full article here: economist.com/finance-and-ec…

I’m a broken record on this, but almost all of the most ~thoughtful~ people I know (or have interviewed) have memorized a lot of dates, places, names, numbers etc. And not just memorized, but care about their ability to recall specifics. Seek truth from facts. It’s the only way.

Dissertation defended 🎓! Grateful beyond words to my committee members @rkoijen, @UncertainLars, Niels Gormsen, Lubos Pastor, and of course, my exceptional advisor @ProfStefanNagel.
Seems as exciting a time as any to share that I'll be spending a couple of months contributing to @TheEconomist on topics in finance and economics, as part of the Marjorie Deane fellowship!
As a longtime fan of @tennisabstract, cool to have my chart on tennis longevity featured in his monthly roundup tennisabstract.com/blog/2025/03/2… (Interactive version here: benmarrow.shinyapps.io/career_wins/)
These @ProfStefanNagel impersonators / scammers are really losing their touch
