This article estimates the mortality cost of smoking using the first labor market estimates of the value of statistical life by smoking status. The value of statistical life is $7 million for both smokers and nonsmokers. Using this value in conjunction with the increase in the mortality risk over the life cycle due to smoking, the value of statistical life by age and gender, and information on ...
