Assuming this data is accurate and sustained (a big assumption, and the usual caveats must apply), this sort of item is going to make the nanny statists out there feel very uncomfortable:
In recent history, the UK has liberalized its rules concerning the hours that pubs can operate. For example, the Licensing Act of 1988 expanded Sunday hours and no longer required pubs to close for two and a half hours in the afternoon. In 2005, the law in England and Wales was further liberalized such that pubs could remain open until 5 am instead of closing at 11 pm. An article in the latest issue of the Journal of Health Economics claims that the 2005 liberalization of pub hours actually decreased the number of traffic accidents.
So writes James Schneider, over at the Econlog economics group blog.
Here is another excerpt:
The reduction in traffic accidents for England and Wales are plausibly related to the change in pub hours because the largest reductions occurred during weekend nights and early mornings. The impact on young drinkers was particularly strong. Accidents involving young people on Friday and Saturday nights decreased by an estimated 32.5 percent.
So there is evidence, perhaps, to confirm a general, common-sense sort of view that if you treat adults like adults, they behave accordingly. It is interesting that the message of this article is as troubling for the paternalist Right as it is for the Fabians on the left. I remember reading some time ago the author Theodore Dalrymple, who has made something of a name by lamenting the alleged ghastliness of modern life in the UK, reticent past, having a pop at liberalised pub hours. The Daily Mail, for example, regularly has a go and rarely fails to write stories about how we Brits are living in a sea of booze.
And yet it turns out that there has been a coincident sharp fall in road accidents on one hand, and looser licensing laws, on the other. It should be borne in mind, though, that recent years have seen a continued strong enforcement of drink-drive laws; police are pretty tough on speeding in general; there may be, for demographic reasons, just fewer tearaways on the roads in general. On the other hand, our island is more crowded than it used to be and our roads are busier, so you might think there would be more risk of accidents, not less. And yet the number of accidents, including fatal ones, has fallen.
Correlation is not causation. It is, however, worth noting that had the number of road accidents risen significantly at around the same time as our drinking laws had changed, I think I can imagine how organisations such the British Medical Association, The Lancet, and other campaigners would have used such sets of data.
