Steve Levitt of Freakonomics fame wrote an interesting paper recently that strongly suggested that car seats did not assist in preventing child fatalities in car crashes any more than seat belts. A link to his article and related findings is here.
Now when I proudly brought this excellent piece of econometric research home as evidence as to how we could free up space in the car, I was informed that our household behaviour would not be changing. Car seats all around until they are well beyond 6 years old. Well, we had the seats anyway (4 or 5 by last count between various cars and ages and a total expenditure of $1000).
I suspect that reaction will be similar. Give parents and option and suggest that it will have a marginal improvement in safety and they will demand it in droves. Get some government regulations and it is entrenched forever.
But one wonders how far this might go. Suppose I developed a cocoon type restraint whereby you took said children, put them in a coffin like structure with a little window to look out of and staked them neatly in the boot of the car or SUV. Now I am pretty sure I could get some engineer to demonstate their safety properties. Coupled with an alluring idea of having the kids out of sight while driving (whine free!) and I think this is a winning product.
Parental demand for safety (subject to wealth constraints) seems to me to be unlimited and as close to inelastic as we are ever going to find. Although against this is the fact that we are yet to see the 'Safe and Silent Cocoon.' Nonetheless, an issue of public policy makers interested in consumer protection is how to restrain parental purchases of unnecessary equipment. I for one could use some restraint.
