Wayne Crews recently posted an editorial on cost-benefit analysis and regulations. It’s worth a read.
In the 1970s the Carter administration prohibited speedometers from indicating speeds over 85 miles per hour. The idea was around before Carter, but his people implemented it.
Regulations require some justification. The justification was, people might not drive fast if they didn’t know how fast they were going. After some hand-waving and pulling numbers out of orifices it’s possible to fabricate a number of accidents and deaths per year prevented and call that the benefit of the regulation.
As part of Reagan’s regulatory reform the speedometer rule was scrapped. Rescinding a regulation requires some justification. The justification was that there was no real evidence that limiting indicated speed would reduce or had reduced driving speed.
An ineffective regulation is harmful because it imposes costs with no benefits.
