2008年美国次贷危机爆发后,货币主义理论沦为千夫所指,凯恩斯主义复兴之火被重新点燃。凯恩斯主义学者们指责,美联储一直盲目相信市场的正确性,坚持通过大幅降息的方法增加市场流动性,“格林斯潘主义”的这种长期低利率政策造成了各种投机性泡沫(房地产泡沫、股市泡沫和信贷消费泡沫等)的形成。于是,各国政府纷纷推出扩张性的财政政策来刺激经济,一时间,仿佛只有政府的万能之手才能化解金融危机,一度有“凯恩斯主义成功复辟”的说法。 After the outbreak of the subprime mortgage crisis in the United States in 2008, the theory of monetarism fell into the meanings of many people and the fire of Keynesian revival was rekindled. Keynesian scholars have accused the Federal Reserve of blind faith in the correctness of the market and its insistence on increasing market liquidity by cutting interest rates sharply. This long-term low interest rate policy of “Greenspanism” has created various speculative bubbles (real estate Bubble, stock market bubble and credit consumption bubble). As a result, governments of all countries have launched expansive fiscal policies to stimulate the economy. For a time, it seems as if only the government’s all-powerful hand can defuse the financial crisis. At one time, there was “the successful restoration of Keynesianism.”
