  Abstract:
  
  Interpersonal comparisons can be of utility levels and/or of utility differences. Comparisons of levels can be used to define equity in distributing income. Comparisons of differences can be used to construct an additive Bergson social welfare function over income distributions. When both utility levels and utility differences are compared, one can require the constructed additive Bergson social welfare function to indicate a preference for more equitable income distributions. This restricts the form of both the individual utility functions and the optimal distribution of income. The form of these restrictions depends on whether the levels and differences of the same utility functions are being compared. ScienceDirect link.

  Abstract:
  
  By definition, “consequentialist” behaviour in finite decision trees is explicable by its consequences. Both cost–benefit tests and “consequentialist” choices of economic policy necessarily require distributional judgements. These should emerge from a social welfare objective incorporating interpersonal comparisons. To accommodate them, Arrow’s IIA condition should be weakened to independence of ethically irrelevant alternatives. When consequences are risky, dynamically consistent consequentialist behaviour on an unrestricted domain of finite decision trees entails maximizing expected social welfare. Combined with an “ethical liberalism” condition, this leads to “fundamental” utilitarianism, which requires a further weakening of IIA to independence of ethically irrelevant mixed alternatives.
