'The recognition of the importance of complex systems in physics and biology has led to their study in economic systems, usually characterized as governed by a large set of interacting nonlinear dynamic systems. It is clear that these phenomena are observable and are not necessarily inconsistent with standard economic reasoning. Professor Rosser has collected a large number of papers, some from not-easily-accessible sources, which show the application of complex system theory to a variety of economic phenomena. This collection will be invaluable to the development of new and necessary thinking in economics.'- Kenneth J. Arrow, Stanford University, US Complex dynamics in economics arise from nonlinear systems that do not converge to a fixed point, a limit cycle, or explode or implode exponentially due to endogenous factors. They arise from cybernetics, catastrophe theory, chaos theory, or the varieties of modern complexity theory, including models with heterogeneous, interacting agents. This major three-volume collection presents the most important papers in the area of complexity in economics. Topics include: Volume I: Philosophical and Methodological Overviews; Social Interactions and Learning Dynamics; Competitive Market Dynamics; Dynamics of Imperfect Competition; Volume II: Macroeconomic Fluctuations and Growth; Financial Markets; International and Transition Economic Dynamics; Volume III: Urban and Regional Systems; Evolutionary Economic Dynamics; and Ecologic-Economic Systems. Complexity in Economics is an authoritative and invaluable reference source for all those with an interest in this area.
