复杂经济周期下的非线性微观经济动力学模型

Current framework of microeconomics is static, self-centered optimization, ignoring the Smith theorem, i.e. the division of labor is limited by market extent. Equilibrium economics fails to.understand persistent cycles in macroeconomics, over-investment and financial crisis in finance theory. We has developed dynamical model of industry competition, which integrates the ideas of the market extent by Adam Smith, Entreprunership by Schumpeter, and over-investment by Austrian.school. Our model provides an unified theory for instabilities in macro economies and financial markets, including product cycles, long technology waves, excess capacity, mass psychology,growth trends, and persistent cycles. Neo-classical synthesis emphasize the role of insufficient demand in market disequilibrium. We find out that over-investment for competing market-extent is the fundamental cause of business cycles and financial crisis. Our work has paved the foundation to economic physics.
