DSGE为什么有这么多诟病?

当你自吹自擂有了DSGE连理工科的数学也足够应付的时候，我就在别的地方说，你的知识随着你的DSGE的高深而肤 ...

楼主对DSGE模型的理解很深入，佩服下。
不过更同意你的这段话，大意我翻译下：无论什么模型，它仅仅是工具，喧宾夺主地用，然后再把问题归罪到工具上，是知识领域不成熟的表现。

from Lars Syll Commenting on the state of standard modern macroeconomics, Willem Buiter argues that neither New Classical nor New Keynesian microfounded DSGE macro models has helped us foresee, understand or craft solutions to the problems of today’s economies: The Monetary Policy Committee of the Bank of England I was privileged to be a ‘founder’ external member […]

世界是复杂的，相比较而言再复杂的DSGE也是简单的，所以只能把它作为分析的一部分，想依靠一个简单的模型来理解全部本来就是很困难的。

好帖子 学习了

useful discussions, thanks

可參閱 RBC and NK in a Nutshell
其中 Stephen Williamson:
That NK story about monetary policy seems pretty crude.
Shouldn't we elaborate more on what central banks actually do?
Shouldn't we include financial factors in both the RBC and NK stories?

楼上有人评价说“换句话说，刀是快刀，刀法有问题。”很好！
