【摘要】：2008年以来的全球金融危机引发了学界对主流宏观经济学是否陷入"麻烦"的讨论。对此,本文回顾了现代宏观经济学体系下新兴古典主义与新凯恩斯主义相继兴起的历程,并对近年来新兴的行为宏观经济学的缘起、发展与演进趋势做出评述。本文认为,所谓的"麻烦"仅是主流宏观经济学在各个时期所遭遇的无法解决实践问题的暂时性困难,而其近30多年的发展演变恰是不断对其微观基础进行修正以解决各种"麻烦"的过程。如果说新兴古典主义实现了基于个体理性的微观建模,那么新凯恩斯主义则是在其中加入了市场摩擦因素,行为宏观经济学又将之推进至个体背离理性的异质性认知层次,这充分体现了层层递进式的理论演进规律。可以预料的是,行为宏观经济学也并非主流宏观经济学的终极版本,必将随着新的社会经济问题的出现而得到进一步改进。
[Abstract]:The global financial crisis since 2008 has triggered a debate about whether mainstream macroeconomics is in trouble. This paper reviews the rising process of emerging classicism and neo-Keynesianism under the system of modern macroeconomics, and comments on the origin, development and evolution trend of emerging behavioral macroeconomics in recent years. This paper holds that the so-called "trouble" is only a temporary difficulty encountered by mainstream macroeconomics in various periods that cannot solve practical problems. Its development and evolution in recent 30 years is the process of constantly revising its microscopic basis to solve all kinds of troubles. If the emerging classicism has realized the micro modeling based on individual rationality, then the new Keynesianism has added the market friction factor in it, and the behavior macroeconomics has pushed it to the heterogeneous cognitive level of individual deviating from rationality. This fully reflects the evolution law of the progressive theory. It can be expected that behavioral macroeconomics is not the ultimate version of mainstream macroeconomics and will be further improved with the emergence of new social and economic problems.
