Theory of Financial Decision Making

by Jonathan Ingersoll

📖 Overview

Theory of Financial Decision Making presents core principles and mathematical frameworks for analyzing investment choices and asset pricing. The book covers utility theory, risk aversion, portfolio selection, and equilibrium asset pricing models. The text moves systematically through fundamental concepts to advanced topics like stochastic dominance, contingent claims, and option pricing theory. Each chapter builds on previous material while incorporating practical examples and theoretical proofs. Mathematical derivations and formal economic arguments form the foundation of the work, with an emphasis on rigorous development of key results. The book includes extensive problem sets and mathematical appendices. This text serves as both a reference work for researchers and a graduate-level teaching tool, addressing fundamental questions about how investors make decisions under uncertainty and how markets price risk.

👀 Reviews

Readers describe this as a mathematically rigorous finance text best suited for PhD students and researchers. Multiple reviewers note it contains deep theoretical foundations but requires advanced math knowledge, particularly in stochastic calculus and optimization. Likes: - Clear derivations of complex concepts - Comprehensive coverage of asset pricing theory - High-quality problem sets and examples - Detailed treatment of contingent claims Dislikes: - Dense notation that can be hard to follow - Limited practical applications - Some sections need updating for current markets - High price point ($150+ for new copies) Ratings: Goodreads: 4.4/5 (17 ratings) Amazon: 4.3/5 (6 reviews) One PhD student reviewer noted: "The mathematical treatment is elegant but you need strong prerequisites to appreciate it." Another mentioned: "This remains the definitive theoretical treatment of derivatives pricing, though newer books cover more recent developments."

🤔 Interesting facts

📚 Jonathan Ingersoll served as the Adrian C. Israel Professor of International Trade and Finance at Yale School of Management, bringing decades of expertise to this comprehensive work. 💡 The book, published in 1987, became one of the first texts to extensively explore the connections between continuous-time finance and arbitrage pricing theory. 📈 The mathematical framework presented in this book heavily influenced how modern financial derivatives are priced and risk-managed on Wall Street. 🎓 Many top finance PhD programs have used this text as required reading, particularly for its rigorous treatment of stochastic calculus in financial applications. 🏆 Ingersoll's work contributed significantly to the development of the term structure of interest rates theory, which he thoroughly examines in this book's later chapters.
