AD-AS-BP模型及其政策效应

AD-AS-BP Model and its Policy Effect

"滞胀"现象的出现使凯恩斯理论濒临崩溃,是AD-AS模型使其得以复活。现实中,任何经济系统都是开放的。然而,当我们把AD-AS模型推广到开放经济条件下,通过构建AD-AS-BP模型并据此进行政策效应分析时却发现,凯恩斯主义降低人们等待成本的总需求政策,即便是在短期内对于经济增长、失业和通货膨胀问题的分别解决也总是失效的。

The appearance of stagflation brought the Keynesian Theory to the edge of breaking down. It is the AD-AS model that salvage it. In reality, all the economic systems are open. Meanwhile, when the AD-AS model is used in the open economy, with the formation of the model of AD-AS-BP and its use in analyzing the policy effect, it is not difficult to see that the gross demand policy in Keynesian always fail when used to analyze the economic growth, unemployment and inflation.
