About this book

Symmetry and Economic Invariance (second enhanced edition) explores how the symmetry and invariance of economic models can provide insights into their properties. Although the professional economist of today is adept at many of the mathematical techniques used in static and dynamic optimization models, group theory is still not among his or her repertoire of tools. The authors aim to show that group theoretic methods form a natural extension of the techniques commonly used in economics and that they can be easily mastered. Part I provides an introduction that minimizes prerequisites including prior knowledge of group theory. Part II discusses recent developments in the field.

Reviews

From the book reviews:

“The monograph provides an introduction to the application of group theory, a mathematical tool, to examine the structure of economic models. … It will be useful for postgraduate students and researches specializing in dynamical models of economics.” (Sergei Georgievich Zhuravlev, zbMATH, Vol. 1291, 2014)

Professor Sato also writes columns regularly for several Japanese newspapers.

Professor Sato, who was a Fulbright Scholar, received his B.A. in economics and his Dr. Economics from Hitotsubashi University in Tokyo, and his Ph.D. in economics from Johns Hopkins University. His principal areas of research interest are mathematical economics and economic growth.

Rama V.Ramachandran

Rama V.Ramachandran received his master’s degree from Madras University, India, and his Ph.D. from Brown University in the U.S.A. He was a faculty member of the Department of Economics of Southern Methodist University and the Department of Economics of the Stern School of Business, New York University. He was associate director of the Center for Japan–U.S. Business and Economics at the Stern School. His research interests were in microeconomics and growth theory. After retirement, he has focused on economic pedagogy and authored an innovative introduction to microeconomics, Opportunities and Choices: Understanding Our Economic Decisions.
