Encouraging safe cycling

And in another good one — “Intended and Unintended Effects of Youth Bicycle Helmet Laws” by Christopher S. Carpenter, Mark F. Stehr. (Paper again gated).

Over 20 states have adopted laws requiring youths to wear a helmet when riding a bicycle.  We confirm previous research indicating that these laws reduced fatalities and increased helmet use, but we also show that the laws significantly reduced youth bicycling.  We find this result in standard two-way fixed effects models of parental reports of youth bicycling, as well as in triple difference models of self-reported bicycling among high school youths that explicitly account for bicycling by youths just above the helmet law age threshold.  Our results highlight important intended and unintended consequences of a well-intentioned public policy.

Everytime I mention bikes there is a raft of comments. The issue here is what the kids are doing if not cycling. Chances are they are not wearing helmets doing it.

  1. It seems strange that you would only require youths to wear helmets.  I can’t remember, but was the Victorian law phased in in such a fashion back in the mid-80s?
