Quick Summary
Princeton and Yale economists Dixit and Nalebuff translate game theory into accessible principles for strategic thinking, covering backward reasoning, prisoners' dilemmas, mixed strategies, credible commitments, information asymmetry, auctions, bargaining, voting, and incentive design with applications across business, politics, and everyday life.
Detailed Summary
"The Art of Strategy" by Avinash K. Dixit and Barry J. Nalebuff, published by W. W. Norton in 2008, is a substantially revised and expanded version of their 1991 classic "Thinking Strategically." The authors, professors at Princeton and Yale respectively, aim to make the insights of game theory accessible to a broad audience while maintaining intellectual rigor.
The book is structured in three parts. Part I introduces strategic thinking through ten illustrative tales, then covers games solvable by backward reasoning (where you reason from the end of a game to determine optimal moves at each stage), the classic Prisoners' Dilemma and mechanisms for resolving it (including repeated play, reputation effects, and institutional design), and Nash equilibrium -- the concept that earned John Nash the Nobel Prize. The epilogue to Part I places these concepts in historical context.
Part II addresses situations involving uncertainty and strategic moves. The chapter on choice and chance integrates probability into strategic decision-making, covering mixed strategies and the value of randomization. Strategic moves are analyzed in terms of threats, promises, and commitments, while a dedicated chapter examines how to make strategies credible through mechanisms such as burning bridges, reputation building, and contractual devices. The section includes a discussion of the Nobel Prize history of game theory, covering the contributions of Harsanyi, Nash, Selten, Aumann, and Schelling.
Part III tackles more advanced applications: interpreting and manipulating information (addressing adverse selection, moral hazard, and signaling), cooperation and coordination problems (including focal points and convention), auctions and bidding theory, bargaining (including Nash bargaining solution and alternating-offers models), voting theory (including Arrow's impossibility theorem and strategic voting), and incentive design. The book concludes with case studies and workouts that allow readers to practice applying the principles.
A key evolution from the original book is the increased emphasis on cooperation. The authors note that good strategy must appropriately mix competition and cooperation, moving beyond the purely adversarial framing of their earlier work. The book draws on behavioral game theory, incorporating insights about human psychology and cognitive biases, making the theory more applicable to how people actually behave rather than how rational models predict they should behave.
