【摘要】 新凯恩斯主义的“协调失灵”理论认为 ,在一个由许多经济人构成的分散经济中 ,由于“策略互补”、“溢出效应”、宏观经济外部性等原因 ,市场机制无法成功地协调整体的经济行动 ,宏观经济将会出现多重均衡。经济体系可能持续地陷入低效率的失业均衡中。政府可以通过政策来调整市场的协调机制 ,引导经济从低水平均衡向高水平均衡运动。更多还原

【Abstract】 The “coordination failures” theory of New Keynesian Economics shows that the market mechanism is unable to coordinate individual agent’s actions successfully in economic men, decentralized economy, even if every agent is rational. Because there are such elements as “strategic complementarities”, “spillover effects” and macroeconomic externalities, multiple equilibrium would occur in the macro-economy. As a result, the economy may get bogged down in a bad equilibrium even thought a better equilibrium is attainable. While the economy can not move automatically to the full-employment equilibrium, government must reform the market coordination mechanism and guide the economy move from a lower equilibrium to a higher equilibrium by economic policies.更多还原
