Alvin E. Roth (Moral Economics) is a Nobel Prize-winning economist, Stanford professor, and author. Alvin joins Armchair Expert to discuss growing up in Queens with two schoolteacher parents, skipping a traditional high school path to attend college at 16, and how early academic exposure shaped his curiosity about markets and human behavior. Alvin and Dax talk about pioneering kidney exchange programs that have saved thousands of lives, the surprising ways incentives influence behavior in everyday systems, and how market design applies to everything from matching students to schools to allocating scarce resources. Alvin explains the difference between repugnance and disgust in economics, why some markets are morally contested yet necessary, and why solving complex social issues requires designing better systems rather than relying on good intentions alone.

I am endlessly fascinated by the messiness of being human, and I find people who are vulnerable and honest about their struggles and shortcomings to be incredibly sexy. I invite you to join me as I explore other people’s stories. We will celebrate, above all, the challenges and setbacks that ultimately lead to growth and betterment. What qualifies me for such an endeavor? More than a decade of sobriety, a degree in Anthropology and four years of improv training. I will attempt to discover human “truths” without any laboratory work, clinical trials or data collection. I will be, in the great tradition of 16th-century scientists, an Armchair Expert.
