Many ethical theories, including in particular consequentialist moral the ories, require comparisons of the amount of good possessed or received by different people. In the case of some goods, such as monetary income, wealth, education, or health, such comparisons are relatively unproblematic. Even in the case of such goods there may be serious empirical measurement problems, but there appear to be no difficulties in principle. Thus Cooter and Rappoport maintained that there was no serious difficulty of making interpersonal utility comparisons (...) for an earlier generation of economists who regarded utility as an index of “material welfare.”.

I consider an old problem for preference satisfaction theories of wellbeing: that they have trouble answering questions about interpersonal comparisons, such as whether I am better off than you are, or whether a particular policy benefits me more than it benefits you. I argue that a similar problem arises for intrapersonal comparisons in cases of transformative experience. I survey possible solutions to the problem, and point out some subtle disanalogies between the problem involving interpersonal comparisons and the problem involving transformative (...) experience.
