 Welfare economists tend to ignore such issues because neither Pareto improvements nor Kaldor-Hicks improvements (in their usual interpretations) need information about anything other than preferences. Indeed, standard welfare economics assumes that well-being is all that matters to the evaluation of social outcomes. Most people, however, care also about other values (Sen 1999: Ch. 3; Hausman et al. 2017: Chs 9–12; Reiss 2013: Ch. 14).
