Testing sensitivity of willingness to pay for mortality risk reduction

Contingent valuation method was used in this study to elicit willingness to pay for risk reduction of dying because of cardiovascular or respiratory diseases. The survey was conducted on a sample of 408 citizens of Warsaw between 50 and 80 years of age. Obtained results did not pass external scope test, even in its weak form. The magnitude of risk reduction did not have statistical influence on the probability of accepting the bid.
