Games, Fixed Points and Mathematical Economics (2004)(en)(134s)

Detailed Summary of the Book

The book is rooted in the mathematical principles that underpin game theory and its critical role in economics. It begins with an overview of basic game theory concepts, such as Nash equilibria, cooperative vs. non-cooperative strategies, and repeated games. The text then delves into the mathematical foundation of fixed point theorems, particularly those of Brouwer and Kakutani, which serve as the backbone for proving the existence of equilibria in strategic games and economic systems.

From here, the book bridges the gap between pure mathematics and its applications in economics. It discusses how fixed point methods are instrumental in tackling real-world economic problems, including market equilibria, bargaining theory, and resource allocation. The later chapters focus on equilibrium refinements and computational methods, emphasizing how modern mathematical tools can solve complex strategic problems. By integrating game theory with mathematical tools, the book provides a cohesive narrative that elucidates complex concepts in an accessible manner.

What sets this book apart is its ability to highlight the practical implications of abstract theories. Through exercises and examples, the author ensures that readers not only understand the theories but also learn how to apply them to problems in economics and beyond.
