今日佳句101027

来自Matt Ridley

It takes unusual courage for a regulator to stand up and say "something must not be done," lest "something" makes the problem worse.

他谈论的是这篇综述,摘要如下:

Thus far psychological input has been used in economics mainly to highlight the cognitive imperfections of market participants. However, cognitive psychology offers many findings that may be instrumental in emphasizing the limits of government intervention. I survey psychological literature and propose some concepts that may be relevant to the political economy of government regulation.

Arnold Kling引用了第七页上的这句:

In the context of political economy, overconfidence takes the form of the contention of regulators that they fully understand the problems they face and are able to design optimal solutions for them.

  1. 我觉得还有一个incumbent bias的问题。自由竞争的受益是系统性的,没有一个具体的获益人(或许太分散比如消费者,或许没有出现比如随市场开放产生的新竞争者)。产业政策的受益人是具体的,现有竞争状况下的参与者。而政治逻辑总是会哭的孩子有奶吃。
