For more than three decades, macroeconomics has gonebackwards. The treatment of identification now is no more credible than in theearly 1970s but escapes challenge because it is so much more opaque.Macroeconomic theorists dismiss mere facts by feigning an obtuse ignoranceabout such simple assertions as "tight monetary policy can cause arecession." Their models attribute fluctuations in aggregate variables toimaginary causal forces that are not influenced by the action that any persontakes. A parallel with string theory from physics hints at a general failuremode of science that is triggered when respect for highly regarded leadersevolves into a deference to authority that displaces objective fact from itsposition as the ultimate determinant of scientific truth.
在此之前，2015年他发表在AER上的一篇文章Mathiness in the Theory of Economic Growth批评了数学在增长理论中的滥用，经济学家的数学模型并未带来增长思想的飞跃和增长政策的进步。
下面把两篇文章放在一起，供感兴趣的朋友查阅。
