Why do people in rich countries not transfer more of their income to people in the world's poorest countries? To study this question and the relative importance of needs, entitlements, and nationality in people's social preferences, we conducted a real effort fairness experiment where people in...

The paper reports the first experimental study on people's fairness views on extreme income inequalities arising from winner-take-all reward structures. We find that the majority of participants consider extreme income inequality generated in winner-take-all situations as fair, independent of...

A core question in the contemporary debate on distributive justice is how the fair distribution of income is affected by differences in talent and effort. Important theories of distributive justice, such as strict egalitarianism, liberal egalitarianism and libertarianism, all give different...

We investigate the properties of a new equity condition, Hammond Equity for the Future (HEF), capturing the following ethical intuition: A sacrifice by the present generation leading to a uniform gain for all future generations cannot lead to a less desirable utility stream if the present...

Koopmans’s (Econometrica 28, 287–309) axiomatization of discounted utilitarianism is based on seemingly compelling conditions, yet this criterion leads to hard-to-justify outcomes. The present analysis considers a class of sustainable recursive social welfare functions within Koopmans’s...

In the framework of ethical social choice theory, sustainability is justified by Efficiency and Equity as ethical axioms. These axioms correspond to the Suppes-Sen Grading principle. In technologies that are productive in a certain sense, the set of Suppes-Sen maximal utility paths is shown to...

According to liberal egalitarian ethics, individuals should be rewarded for factors under their control, but not for factors outside their control. A fundamental challenge to liberal egalitarian theories of justice is how to do this without violating minimal egalitarian and liberal requirements....

A liberal egalitarian theory of justice seeks to combine the values of equality, personal freedom and personal responsibility. It is considered a much more promising position than strict egalitarianism, because it supposedly provides a fairness argument for inequalities reflecting differences in...
