The distribution of oportunities: a normative theory

In this paper, we consider the problem of ranking protiles of opportunity sets. First, we take each agent's preferences over (individual) opportunity sets as given. Then, rather than discriminate among possibly competing evaluative criteria, we consider minimal standards for any such ranking. We impose four normative principies, in each case limiting the conditions under which ethical conclusions might be drawn to only those cases that are unambiguous. The first three principles are subrestrictions of the Pareto criterion; they require that Pareto improvements unambiguously enhance social welfare only when they do not conflict with other social objectives. The fourth principle is a minimal equity condition. It requires that if an agent can be identified as being the worst-off, then a necessary condition for social welfare to unambiguously increase when sorne agents gain is that this agent gains as well, however slightly. We then study the properties of social optima under these restrictions. We show that while optima need not be Pareto efficient, they must be envy-free. Thus, accepting these principies requires commitment to a world in which no agent envies the opportunities available to another

Equitable opportunities in economic environments

In this paper, we extend the axiomatic analysis of equitable opportunities developed in Kranich [6] from finite to continuous opportunity sets. This extended framework is amenable to economic applications. The main results establish conditions under which an ordinal ranking of profiles of opportunity sets can be represented by a cardinal advantage function which describes both the extent of inequality and the distribution of advantage among the agents

Equity and economic theory: reflections on methodology and scope

This paper provides an introduction to the recent literature on ordinal distributive justice. Its objetive is to explain the process of the mathematical analysis of fairness and to consider its potential for solving real allocative problems by means of several illustrative examples
