title: Altruistic Preferences in Time Tradeoff: Consideration of Effects on Others in Health State Valuations.
abstract: Whether respondents incorporate altruistic preferences in time tradeoff (TTO) exercises remains understudied. We present an extended quality-adjusted life-year model incorporating altruism. We derive that altruism may affect TTO values in 2 directions. First, "longevity altruists" may wish to prolong life for the sake of their loved ones (to avoid being missed). Second, "quality-of-life altruists" may have a preference to avoid bad health states resulting in being a burden to loved ones. The existence and influence of these preferences in a TTO were empirically confirmed in a sample of 1690 respondents from the general public. We classified respondents as "longevity altruists" or "quality-of-life altruists" based on their reasoning behind inclusion of loved ones in their TTO responses. In line with expectations, longevity altruists traded fewer years than quality-of-life altruists. Nonaltruists gave intermediate values.
