The Capability Approach
Introduced by Nobel laureate Amartya Sen (1979), applied in Human Development and Management (The capability approach is a theoretical framework that entails two core normative claims: first, the claim that the freedom to achieve well-being is of primary moral importance, and second, that freedom to achieve well-being is to be understood in terms of people's capabilities, that is, their real opportunities to do and be what they have reason to value. The approach has been developed in a variety of more specific normative theories, such as (partial) theories of social justice or accounts of development ethics. It has also led to a new and highly interdisciplinary literature in the social sciences resulting in new statistics and social indicators, and to a new policy paradigm which is mainly used in development studies, the so-called ‘human development approach’. Initially, Sen argued for five components in assessing capability:
1. The importance of real freedoms in the assessment of a person's advantage
2. Individual differences in the ability to transform resources into valuable activities
3. The multi-variate nature of activities giving rise to happiness
4. A balance of materialistic and nonmaterialistic factors in evaluating human welfare
5. Concern for the distribution of opportunities within society
Subsequently, and in collaboration particularly with political philosopher Martha Nussbaum, development economist Sudhir Anand and economic theorist James Foster, Sen has helped to make the capabilities approach predominant as a paradigm for policy debate in human development where it inspired the creation of the UN's Human Development Index (a popular measure of human development, capturing capabilities in health, education, and income). In addition, the approach has been operationalised with a high income country focus by Paul Anand and colleagues. Furthermore, since the creation of the Human Development and Capability Association in the early 2000s, the approach has been much discussed by political theorists, philosophers, and a range of social scientists, including those with a particular interest in human health.
The approach emphasizes functional capabilities ("substantive 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-fulfillment 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 humans actually function but also on their having the capability, which is a practical choice, "to achieve outcomes that they value and have reason to value". Everyone could be deprived of such capabilities in many ways, e.g. by ignorance, government oppression, lack of financial resources, or false consciousness.
This approach to human well-being emphasizes the importance of freedom of choice, individual heterogeneity and the multi-dimensional nature of welfare. In significant respects, the approach is consistent with the handling of choice within conventional microeconomics consumer theory, although its conceptual foundations enable it to acknowledge the existence of claims, like rights, which normatively dominate utility-based claims (see Sen 1979).
