Les consentements à payer pour des programmes de prévention sanitaire incluent-ils de l'altruisme ?. Enseignements d'une enquête sur la fièvre Q

Increasingly, the assessment of health prevention policies is evaluated through willingness to pay (wtp) surveys. When the evaluation deals with policies with a public dimension, the individual?'s stated wtp can reflect an altruistic component, which may alter the results of the economic valuation. By applying an expected utility framework in a contingent valuation survey on Q fever, we can determine the individuals who integrate an altruistic component in their stated wtp (or not) that we further explain by explanatory variables. The main result is that 66 percent of respondents express an altruistic component when they state their wtp for the collective program. The part devoted to an altruistic motive is on average equal to 3,6 euro, nearly 25 percent of the considered wtp.Classification JEL : C25, D64, D841, I1
