March 27, 2014 01:30 PM
In The Effect of Mandatory Seat Belt Laws on Seat Belt Use by Socioeconomic Position, authors Sam Harper, Erin C. Stumpf, Scott Burris, George Davey Smith, and John Lynch identified the differential effect of legislation across higher versus lower education individuals. This paper, published in the Winter 2014 Journal of Policy Analysis and Management, uses a difference-in-differences model based on state variations in the timing of the passage of laws. The authors found strong effects of mandatory seat belt laws for all education groups, with a stronger effect for those with fewer years of education. Additionally, the authors found that the differential effect by education is larger for mandatory seat belt laws with primary rather than secondary enforcement. These results imply that existing socioeconomic differences in seat belt use would be further mitigated if all states upgraded to primary enforcement.
