Choices involving risk significantly affect the distribution of income and wealth in society. This paper reports the results of the first experiment, to our knowledge, to study fairness views about risk-taking, specifically whether such views are based chiefly on ex ante opportunities or on ex post outcomes. We find that, even though many participants focus exclusively on ex ante opportunities, most favor some redistribution ex post. Many participants also make a distinction between ex post inequalities that reflect differences in luck and ex post inequalities that reflect differences in choices. These findings apply to both stakeholders and impartial spectators.

A core question in the contemporary debate on distributive justice is how to understand fairness in situations involving production. Important theories of distributive justice, such as strict egalitarianism, liberal egalitarianism, and libertarianism, provide different answers to this question. This paper presents the results from a dictator game where the distribution phase is preceded by a production phase. Each player's contribution is a result of a freely chosen investment level and an exogenously given rate of return. We estimate simultaneously the prevalence of three principles of distributive justice among the players and the distribution of the weight they attach to fairness.
