Article Summary In a blog posting in the New York Times, Daniel Hamermesh cited a recent study conducted by researchers at Michigan State University which claims that states that repeal mandatory motorcycle helmet laws see an increase in organ donations from fatal motor vehicle accidents. According to the study, when states repeal mandatory motorcycle helmet laws, organ donations due to fatal accidents increase by 10 percent. The study estimates that for each death of a motorcyclist who was not wearing a helmet, 0.33 deaths are delayed or prevented among those on organ transplant waiting lists. In a conversation with colleagues prior to the state implementing a mandatory helmet law, a California surgeon stated ʺmotorcycle fatalities are ...our number one source of organsʺ. Source: Richard S. Chang, ʺMotorcycle Helmets and Donor Organs,ʺ New York Times, June 22, 2009. 3) Refer to the Article Summary. Mandatory motorcycle helmet laws are designed to reduce the severity of injuries resulting from motorcycle involvement in traffic accidents, but they also have been shown to reduce the number of organs available for transplant. By decreasing the number of transplantable organs, these mandatory helmet laws produce A) social benefits. B) a positive externality. C) a negative externality. D) public goods.
