国际金融危机与凯恩斯主义

The Global Financial Crisis and Keynesian Economics

从理论影响实践政策的角度来看,凯恩斯主义和新自由主义经济学对当前国际金融危机的爆发都负有不可推卸的责任。此轮各国的救市政策本质上仍然属于凯恩斯主义式的救急方案,并不会改变西方社会中自由市场制度的根本基础。目前共享宏观经济学主流地位的新凯恩斯主义和新古典主义都是自由市场制度的拥护者,各种形态的凯恩斯主义反对的只是自由放任主义形态的市场经济。即使是新凯恩斯主义者对政府使用短期政策目标来管理长期经济增长的智慧也持谨慎态度。通过长期的争论,它们的理论分歧原本就在不断缩小,这次金融危机将会加速它们的理论融合。

Considering the dominating effect of their theories in policy-making, both Keynesianism and Neo-liberalism economics has played an essential role in the underlying causes of the current crisis, and therefore, should bear inescapable responsibility for the global financial crisis. The current response to this crisis of western governments is none the less Keynesian rescue plan, and will not change the free market system as economic foundation. Actually, Keynesianism and Neo-liberalism that share the dominating role in macroeconomics are both advocators of free market system, although Keynesian economists argue against laissezfaire liberalism. Even new Keynesian economists are suspicious of the efficiency of short-term policy in long run. The gap between the two ideas is closing while their debating and learning from each other, and current crisis will accelerate the theoretic integrative process.
