Abstract
We evaluate the effects of disease type and latency on willingness to pay (WTP)
to reduce environmental risks of chronic, degenerative disease. Contingent-valuation data
were collected from approximately 1,250 respondents in Taiwan. These data suggest the
existence of a “cancer premium:” WTP to reduce risk of cancer is estimated to be about
30 percent larger than WTP to reduce risk of a similar chronic degenerative disease. The
value of risk reduction also depends on the affected organ, environmental pathway, or
payment mechanism: WTP to reduce the risk of lung disease due to industrial air
pollution is estimated to be twice as large as WTP to reduce the risk of liver disease due
to contaminated drinking water. Finally, we find that WTP is insensitive to the latency
period between exposure to environmental contaminants and manifestation of disease.
This insensitivity suggests that respondents anticipate their value per statistical life will
grow over time at a rate about equal to their discount rate.
