关于作者
《Who Gets What》作者介绍
Alvin E. Roth, Nobel laureate and pioneer in market design, is the acclaimed author of Who Gets What – and Why, a groundbreaking exploration of how markets function. A Craig and Susan McCaw Professor of Economics at Stanford University, Roth’s work blends game theory, experimental economics, and practical solutions to real-world problems—revolutionizing systems like kidney donor exchanges and school choice programs.
His expertise stems from decades of research, including influential roles at Harvard and the University of Pittsburgh. Roth's 2012 Nobel Prize in Economic Sciences, which he shared with Lloyd Shapley, solidified his status as a leader in matching theory.
Roth’s other seminal works, such as Two-Sided Matching and The Shapley Value, further establish his authority in economic modeling. Known for translating complex theories into accessible insights, his writing appeals to scholars and general readers alike. Who Gets What – and Why has garnered widespread acclaim, reflected in its 3,000+ Goodreads ratings and adoption in academic curricula globally.

Who Gets What and Why explores "matching markets," where prices don’t dictate outcomes. Nobel laureate Alvin Roth explains how systems like kidney donor exchanges, college admissions, and job markets use algorithms to pair supply and demand. The book highlights market design principles, emphasizing stability and efficiency in critical real-world scenarios like healthcare and education.
This book suits economics enthusiasts, policymakers, and professionals in education, healthcare, or HR. It’s ideal for readers seeking to understand how invisible markets shape decisions in dating apps, school placements, and organ donations. Roth’s accessible examples make complex concepts engaging for both experts and general audiences.
Key ideas include:
- Matching markets: Systems where compatibility trumps pricing (e.g., kidney exchanges).
- Market design: Creating rules to improve fairness (e.g., school choice algorithms).
- Stability: Ensuring matches aren’t easily undone by better alternatives.
- Repugnant transactions: Ethical limits on markets (e.g., banning organ sales).
Roth details his work designing the New England Program for Kidney Exchange, where incompatible donor-recipient pairs are matched via algorithms. This "kidney chain" model saves lives without monetary incentives, showcasing how engineered markets can address ethical and logistical challenges.
Roth helped redesign this system to place medical graduates into residencies. It uses a deferred acceptance algorithm to ensure stable matches between hospitals and applicants, reducing inefficiencies and improving satisfaction for both parties.
Roth argues that markets like Google’s ad auctions or dating apps aren’t purely price-driven. Poorly designed systems risk congestion, unfairness, or instability—problems solved by intentional market engineering, as seen in school choice reforms.
Some readers find the technical details overwhelming despite its "self-help" marketing. Critics also debate Roth’s stance on monetizing certain markets, arguing his solutions may not scale for highly emotional or ethically charged contexts.
Roth analyzes school choice systems, where algorithms assign students to schools based on preferences and priorities. Well-designed matches reduce strategic behavior (e.g., false rankings) and increase equity, as seen in New York City’s public school reforms.
Commodity markets (e.g., wheat) rely on prices, while matching markets (e.g., jobs) prioritize bilateral compatibility. Roth explains why auctions fail in contexts like marriage or organ donations, requiring tailored solutions.
He debates "repugnant transactions," such as paying organ donors, arguing societal norms limit market feasibility. However, he defends non-monetary systems like kidney exchanges as ethically permissible and life-saving.
As AI-driven platforms dominate hiring, healthcare, and dating, Roth’s insights help users navigate algorithmic transparency and fairness. The book’s principles inform debates on allocating scarce resources like vaccines or green energy subsidies.
Both use economics to explain everyday phenomena, but Roth focuses on designing systems rather than behavioral insights. While Freakonomics explores "why people cheat," Roth tackles "how to build markets that prevent cheating."
