Can anyone really disagree with that? Sometimes it is restricted to a particular episode and is based on evidence accumulated after the fact: Yes, the Soviet economic system was hugely inefficient; yes, the Obama fiscal stimulus of 2009 did reduce unemployment.
经济学家间的共识有利也有弊。有时，共识无伤大雅，比如，经济学家们指出，忽略激励的作用是危险的。你这能反驳这一点吗？有时，共识限定于特定场景，其背后是事实积累起来的证据：是的，苏联经济制度效率极低；是的，奥巴马的2009年财政刺激确实降低了失业。
