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.
