摘要

Broome (Journal of Public Economics, 1993, 50, 149-167) claimed that quality-adjusted life years (Qalys) based on the 'time' method are consistent with individual preferences only if life years are not discounted, and Qalys based on the 'probability' method are consistent with individual preferences only if risk-neutrality over discounted life years holds. This comment shows that the time method is consistent with discounting, if the quality weight is derived in the appropriate way. The time method and the probability method are also shown to be consistent with the risk-adjusted Qaly model, that relaxes the assumption of risk-neutrality.
