Sakamoto, Norihito (2012). "On equality of capabilities" Paper presented at the 9th annual conference of the HDCA, 5-7 September 2012, Jakarta, Indonesia.

In this paper, we examine the theoretical properties of Amartya Sen’s capability approach (Sen 1985) by investigating a formal model which describes a simple exchange economy with unequal abilities. Specifically, we will define and axiomatically characterize the following three classes of distribution rules based on the notion of “equality of capabilities”: (1) distribution rules which assign egalitarian and efficient allocations with respect to capability sets; (2) distribution rules which maximize an intersection of all individuals’ capability sets (we call the intersection of all individuals’ capability sets a common capability set); (3) distribution rules which maximize a common capability set with respect to set inclusion relations.
