Abstract

In discussions about justice, development, well-being and equality, the capability approach (CA)Footnote1 founded by economist Amartya Sen and philosopher Martha Nussbaum attaches central importance to individual human capabilities. These are the effective freedoms or real opportunities of people to achieve valuable ‘beings and doings’ (also called ‘functionings’ by capability theorists). Resources—including technical artifacts—may contribute to the expansion of one’s capabilities, but there may also be all sorts of ‘conversion factors’ in place that prevent this. The approach highlights the ‘multidimensionality’ of well-being and sees people as active agents shaping their own lives. In 1998 Sen won the Nobel Prize in economics for his work, which has deeply influenced the United Nations Development Program (UNDP). In the field of development studies the CA has indeed gained popularity, but this is not the only area of application.
