Thanks! I wrote about this a bit in my monograph on minimalist market design. It explicitly talks about the liver exchange program and the factors in its success in Section 12, but the rest of the monograph is also related to achieving such impact. I hope you find it useful arxiv.org/abs/2401.00307

But during yesterday’s operations, the O donor’s graft proved larger and perfect for a direct transplant to their patient. Still able to perform a 2-way exchange for other pairs, the superior direct transplant was performed. This highlights how crucial exchange system is, even when plans change!

Yesterday, our amazing İnönü University partners showcased dynamic nature of liver exchange! We had an O blood-type patient with a O blood-type donor in a planned 3-way exchange. Pre-op calculations suggested graft size was too small for a direct transplant.

The Turkish opposition held a massive rally today in one of Erdoğan’s most loyal strongholds. A farmer nailed it: "You can’t run a country with radish and turnip. You run it with truth, law, and justice." The turnip bit might be a coincidence — but it still lands a little too well in the U.S.

Last year @shengwuli.bsky.social pointed out that the core tenet of my minimalist market design framework—"Don't fix what's not broken"—echoes Chesterton’s Fence (now discussed in Section 2.2.2). In an age of Trumpian & DOGE policies, this tenet feels especially relevant. arxiv.org/pdf/2401.00307

Bu paylaşımda The Guardian gazetesine haksızlık yapıldığı düşüncesindeyim. Hem Türkiye hem bütün dünyada otokrasi karşıtı, merkez sol ve sosyal olarak liberal görüşü temsil eden bir gazetedir. Keza bu başlığı atması da Türkiye’deki muhalefete güçlü desteğinin göstergesidir.

Erdogan, during his tenure as Mayor of Istanbul in 1990s famously stated “Democracy is like a train: when we reach our destination, we get off.” More than 2 million people gathered today in Istanbul (despite a 9 day holiday) to show Turkish people’s commitment to democracy.

Before his arrest on bogus charges, opposition presidential candidate Ekrem İmamoğlu said: “No salvation alone; either all of us together, or none of us.” His words echo far beyond Turkey — a powerful call to unite against authoritarianism.
