Capability approach

The Capability Approach is a conceptual framework developed by Amartya Sen and Martha Nussbaum for evaluating social states in terms of human well-being (welfare). It emphasizes functional capabilities ("substantial freedoms", such as the ability to live to old age, engage in economic transactions, or participate in political activities); these are construed in terms of the substantive freedoms people have reason to value, instead of utility (happiness, desire-fulfilment or choice) or access to resources (income, commodities, assets). Poverty is understood as capability-deprivation. It is noteworthy that the emphasis is not only on how human beings actually function but on their having the capability, which is a practical choice, to function in important ways if they so wish. Someone could be deprived of such capabilities in many ways, e.g. by ignorance, government oppression, lack of financial resources, or false consciousness.
