"This is a unique account of the role played by 58 figures and diagrams commonly used in economic theory. These cover a large part of mainstream economic analysis, both microeconomics and macroeconomics and also general equilibrium theory. The authoritative contributors have produced a well-considered and definitive selection including some from empirical research such as the Phillips curve, the Kuznets curve and the Lorenz curve. Almost all of them are still found in contemporary textbooks and research. Each entry presents an accurate and concise record of the history of the figure or diagram, including later developments and any controversy that arose in its development. As a whole, the book highlights how the use of geometric methods has played a central part in the development of economic theory and analysis; as a method of discovery, more commonly as a method of exposition and occasionally as a method of proof of propositions in economic theory and analysis. This highly anticipated book will appeal to theorists in microeconomics or macroeconomics, scholars of economic theory and analysis, as well as students in microeconomics, general equilibrium theory or macroeconomics at the advanced undergraduate or graduate level who want a definitive account of some figure or diagram. Historians of economic thought and methodologists will also find this book an invaluable resource."--Publisher's description.
