Living with unfairness: The limits of equal opportunity in a market economy

摘要

Equality of opportunity is often presented as a criterion which reconciles egalitarianism with principles of freedom and responsibility. This paper distinguishes between the principle of starting-line equality, which requires that everyones initial opportunities, assessed in relation to what is publicly known ex ante, are equal, and the principle that equal efforts should yield equal ex post rewards. It argues that the first principle is compatible with allocation of resources through markets but, because of the division of knowledge, the second is not. If we want the opportunities which markets give us, we have to accept ex post unfairness. Earlier versions of this paper were presented at a workshop on the measurement of freedom at the London School of Economics, and at a conference on non-welfarist issues in normative economics at the University of Caen. I thank participants at those meetings, and particularly Tania Burchardt, Marco Mariotti and Franz Prettenthaler, for comments. My work on this paper was supported by the Leverhulme Trust.
