The value of changes in life expectancy
Authors:Sherwin Rosen
Abstract:Valuation formulas for age-specific mortality risks are derived from life-cycle allocation theory under uncertainty and related to empirical estimates of the value of life. A change in an age-specific mortality risk affects all subsequent survivor functions and reallocates consumption and labor supply over the entire life cycle. The value of eliminating a risk to life at a specific age is the expected present value of consumer surplus from that age forward. Approximate numerical extrapolations from cross-section estimates imply that values decrease rapidly in current age and in the distance between current age and age at risk.
