The Value of Private Safety Versus the Value of Public Safety

In this study, one group of respondents is offered to purchase a safety device to be installed in their car, while another group is offered a public safety program (improved road quality) which results in the same size risk reduction. In terms of the value of a statistical life, our results are very reasonable. However, the WTP for the private safety device is higher than the WTP for the public safety measure. Drawing on a model developed by Jones-Lee (1991), we show that some types of altruists may, but need not, be willing to pay more for a private risk reduction than for a uniform risk reduction of the same magnitude. Still, our empirical results are surprising, and further empirical research seems warranted
