In this study, one group of respondents is offered to purchase a safet
y device to be installed in their cars, 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 saf
ety device is higher than the WTP for the public safety measure. Drawi
ng on a model developed by Jones-Lee (1991), we show that some types o
f altruists may, but need not, be willing to pay more for a private ri
sk reduction than for a uniform risk reduction of the same magnitude.
Still, our empirical results are surprising, and further empirical res
earch seems warranted.
