My friend Mark Granovetter’s famous paper on #weakties is cited more than 3X more than ⁦‪Acemoglu, Johnson, Robinson‬⁩’s ⁦‪Nobel-winning masterpiece - it’s worth a read! (A delicious, congruent pairing is work by the ⭐️W.D.Eberle Chair ⁦‪@Stanford.edu‬⁩)

Had a fantastic time at the Econ Dept @universitetsmuseet.bsky.social Loved the thoughtful and open culture, and it was a joy to share/debut my work on preferences for #XAI explainable AI. And yes — I even caught sunny Bergen, so clearly I was spoiled ☀️🇳🇴🇳🇴🇳🇴

Truly amazed by the inspiring culture at @lusemlu.bsky.social — such a warm and engaging department! Thrilled to share my work on opt-in/opt-out, and I can’t wait to visit @lund-university.bsky.social again soon!! 🇸🇪🇸🇪🇸🇪

🚨 Live from Stanford! 🚨 @alroth.bsky.social at the APKD Palo Alto Summit on Extending Kidney Exchange. Incredible progress happening in #India, #Brazil & beyond on kidney & liver exchange, plus donor-initiated chains.

Huge developments —the future is saving more lives. #KidneyExchange

R.I.P. Peter Temin - besides his well known work in economic history he has also contributed to pharmaceutical market design “Nationally, if we keep the current structure, in 50 years only hedge fund managers will be able to afford prescription drugs.”

The only state without a Walgreens pharmacy Many independent pharmacies are in turmoil throughout the US. But a unique law has made North Dakota a haven for mom-and-pop operators.

North Dakota offers a rare natural experiment in #pharmacy #marketdesign/competition: no Walgreens/CVS, and min #PBM vertical integration. A 1963 law fostered decentralized mkt shaping 💊 access. A counterfactual worth watching.

Also Paul’s first REStud paper, if you can believe it!

Harvard Explores New Center for Conservative Scholarship Amid Trump Attacks The Ivy League school has discussed an effort to ‘support viewpoint diversity’ with potential donors. Harvard says the initiative ‘will not be partisan.’

Exclusive: Harvard leaders have discussed creating a center for conservative scholarship as the school fights the Trump administration’s accusations that it is too liberal.

Here's an interesting looking job search. (I remember a time when there weren't searches for market designers...)

Harvard thought it had a cheap copy of the Magna Carta. It turned out to be extremely rare Harvard University for decades assumed it had a cheap copy of the Magna Carta in its collection, a stained and faded document it had purchased for less than $30.

Windfall for @harvard.edu : paid 30 bucks for a copy of the Magna Carta that’s worth about $3M? (a 1297 version was sold at auction in 2007 for $21.3M). Lets find 1,000 more of these… apnews.com/article/harv...
