新古典宏观经济学:理论、模型与问题

New Classical Macroeconomics:Theory,Model and Problems

居于主流地位的新古典宏观经济学未能预测2008年金融危机的发生,这表明新古典宏观经济学存在重大缺陷。本文旨在指出和分析缺陷所在及产生的原因。新古典宏观经济学理论及其实际商业周期模型在研究假设、分析方法及政策推论方面有重大漏洞,出现这种情况的主要原因是新古典宏观经济学家对经济学研究的所谓"科学化"追求以及意识形态偏见,由此可见,西方主流宏观经济学已走入歧途,"修补"或"重建"困难重重。

The fact that the mainstream of new classical macroeconomics failed to predict the recent financial crisis proves that serious drawbacks exist in new classical macroeconomics. This paper tries to find what drawbacks are and why they occur. There are loopholes that exist in research assumptions, analysis method and policy pre- scriptions in new classical macroeconomics theory and the policy-oriented RBC models. The pursuit of pure science and ideological biases are partly to blame. Therefore, the western mainstream macroeconomics has gone astray. The remedies or recreation views proposed thus far cannot solve the inherent problem.
