Asset pricing in discrete time: a complete markets approach

Welcome to a foundational journey through the intricate world of asset pricing, set against the backdrop of complete markets and discrete time. "Asset Pricing in Discrete Time: A Complete Markets Approach" by Ser-Huang Poon and Richard C. Stapleton provides an in-depth, methodical exploration of financial models and concepts that shape our understanding of financial markets today. This book not only serves as a comprehensive guide for students and professionals in finance but also offers insights that enhance your reasoning and analytical skills in understanding market dynamics.

Detailed Summary of the Book

At its core, the book lays out the theoretical foundations of asset pricing within a discrete time setting, emphasizing the relevance of complete markets assumptions. The authors deftly combine economic theories with mathematical rigor to detail how prices are determined in competitive markets. Covering a broad range of topics, they delve into the fundamental theories of consumption and investment, modern portfolio theory, and the Capital Asset Pricing Model (CAPM). The book further extends into state pricing with the introduction of Arrow-Debreu prices and the equivalent martingale measure, which form the crux of derivative pricing.

The narrative progresses by introducing readers to the multifaceted aspects of risk and return, and how these principles apply in a discrete time framework—set against the assumption of complete markets. By showing practical applications and extensive examples, the authors illuminate the real-world idiosyncrasies that finance enthusiasts and professionals may encounter. Given its focus on complete markets, the text also juxtaposes the ideal theoretical approaches with real-world imperfections, offering a bridge to understanding how assumptions can impact financial models and strategies.
