The article discusses how to fairly allocate healthcare resources based on individual preferences and justice principles. The researchers establish rules for representing preferences using quality-adjusted life years (QALYs) and for creating a social welfare function based on QALYs. They find that a specific type of social welfare function is characterized by being impartial to how life years are distributed among individuals. By changing this rule, they identify a utilitarian social welfare function with certain weights. Additionally, they outline rules for a social welfare function that is a combination of power transformations of individual QALYs.
