摘要:The popular discounted utilitarian criterion for infinite horizon social choice has been criticized on the
ground that it treats successive generations unfairly. I propose to evaluate intergenerational welfare with a
rank- discounted utilitarian (RDU) criterion instead. The criterion amounts to discounted utilitarianism on
non-decreasing paths, but it treats all generations impartially: discounting becomes the mere expression of
intergenerational inequality aversion. I show that more inequality averse RDU societies have higher
social discount rates when future generations are better-off. I apply the RDU approach in two benchmark
economic growth models and I prove that it promotes sustainable policies maximizing discounted utility.
