Minimalist Market Design: A Framework for Economists with Policy Aspirations In this monograph, I describe the philosophy, evolution, and successful applications of minimalist market design while also presenting the advancements in matching theory achieved through these applic...

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.

Turkish Opposition Asks Erdogan If US Approved Rival’s Arrest Turkey’s opposition leader Ozgur Ozel on Sunday challenged President Recep Tayyip Erdogan to say whether he received approval from the Trump administration for the recent arrest of Erdogan’s main riva...

A collusion of autocrat wannabes: According to CHP leader Özgür Özel, Erdoğan secured Trump’s tacit approval for the arrest of Turkey’s opposition leader—while Trump, in turn, has been increasingly embracing Erdoğan-style authoritarian tactics.

Given the strong parallels between leadership styles of Trump and Erdogan, and the rapid deterioration of democratic institutions in the US, the same headline equally applies to Americam democracy 🙁

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.

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.

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.

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

Fantastic research program offering solutions to challenges Boston Public Schools officials faced 2 decades ago when choosing between the Deferred Acceptance and Top Trading Cycles. The framework by ‪@charmelades.bsky.social & @aromeromedina.bsky.social could have served as an innovative compromise.
