TL;DR: The results provide weak support for the notion that WTP declines with age, but only after age 70, and the idea that people who have cancer or chronic heart or lung disease are willing to pay less to reduce their risk of dying than people without these illnesses is found no support.

TL;DR: This paper explored the effect of a latency period on willingness to pay (WTP) for reduced mortality risk using both structural and reduced form approaches and found that delaying the time at which the risk reduction occurs by 10 to 30 years reduces WTP by more than half for respondents in both samples aged 40 to 60 years.
Abstract: Using results from two contingent valuation surveys conducted in Canada and the U.S., we explore the effect of a latency period on willingness to pay (WTP) for reduced mortality risk using both structural and reduced form approaches. We find that delaying the time at which the risk reduction occurs by 10 to 30 years reduces WTP by more than half for respondents in both samples aged 40 to 60 years. Additionally, we estimate implicit discount rates equal to 8% for Canada and 4.5% for the U.S. - both well within the range established previously in the literature.
