A Lesson In Unintended Consequencesby Brad Warbiany
Normally, we libertarians know enough about government to predict many unintended consequences of government regulation… But this one took me by surprise:
Although many countries have introduced national bans, America has taken a piecemeal approach. A number of states, counties and municipalities have introduced various types of bans, and have enforced them with varying degrees of rigour.
The problem with this, say Scott Adams and Chad Cotti, economists at the University of Wisconsin-Milwaukee, is that smoking bans seem to have been followed by an increase in drunk-driving and in fatal accidents involving alcohol. In research published in the Journal of Public Economics, the authors find evidence that smokers are driving farther to places where smoking in bars is allowed.
The researchers analysed data from 120 American counties, 20 of which had banned smoking. They found a smoking ban increased fatal alcohol-related car accidents by 13% in a typical county containing 680,000 people. This is the equivalent of 2.5 fatal accidents (equivalent to approximately six deaths). Furthermore, drunk-driving smokers have not changed their ways over time. In areas where the ban has been in place for longer than 18 months, the increased accident rate is 19%.
Good thing we saved everyone from that secondhand smoke!
Now, I’m not going to defend the drunk drivers who are causing these accidents. The drunk drivers are the primary cause of these accidents; the smoking bans are only a contributing factor. But it’s a good lesson about how well-meaning regulations can quite often have disastrous unintended consequences. When politicians tell you about all the beneficial (and largely falsely-promised) effects of a proposed regulation, perhaps the negative effects– that which is unseen– should be anticipated as well.
