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...

This paper studies the pro-social preferences of criminals by comparing the behavior of a group of prisoners in a lab experiment with the behavior of a benchmark group recruited from the general population. We find a striking similarity in the importance the two groups attach to pro-social...

The standard economic approach to tax policy has to a large extent relied on welfarist theories of justice, in particular the utilitarian view that the government should try to maximize the sum of individual welfare. This welfarist framework has proved a productive point of departure for much...

Suppose that there exists a positive (exogenous) probability that at each date of a possibly infinite future, the human species will disappear. We postulate an Ethical Observer (EO) who must solve an intertemporal welfare maximization problem under this kind of uncertainty, with preferences that...

The meritocratic fairness ideal implies that inequalities in earnings are regarded as fair only when they reflect differences in performance. Consequently, implementation of the meritocratic fairness ideal requires complete information about individual performances, but in practice, such...

This paper studies how individual behavior is affected by moral reflection in a dictator game with production, and the informational value of self-reported data on fairness. We nd that making individuals reflect on fairness before they play the dictator game has a moderate effect on the weight...

Fairness preferences fundamentally affect individual behavior and play an important role in shaping social and political institutions. However, people differ both with respect to what they view as fair and with respect to how much weight they attach to fairness considerations. In this paper, we...

In a large-scale pre-registered survey experiment with a representative sample of more than 8,000 Americans, we examine how the COVID-19 pandemic causally affects people’s solidarity and fairness. We randomly manipulate whether respondents are asked general questions about the crisis before...

We model an intergenerational society, with a representative agent at each date, who must deplete a renewable resource, from which he derives utility, to produce consumption goods. We adopt the intergenerational lexicographic minimum as the social welfare function. Initially, technological...

Egalitarian theorists, since Rawls, have in the main advocated equalizing some objective measure of individual well-being, such as primary goods, functioning, or resources, rather than subjective welfare. This discussion, however, has assumed, implicitly, a static environment. By analyzing a...
