Inequality averse criteria for evaluating infinite utility streams: the impossibility of Weak Pareto. (English) Zbl 1258.91054

Summary: This paper investigates ethical aggregation of infinite utility streams by representable social welfare relations. We prove that the Hammond Equity postulate and other variations of it like the Pigou-Dalton transfer principle are incompatible with positive responsiveness to welfare improvements by every generation. The case of Hammond Equity for the Future is investigated too.
