Abstract
Capability approach pioneers Amartya Sen and Martha Nussbaum both recognize empowerment as an
important aspect of human development. They seem to disagree, however, about how empowerment
should be represented within the capability approach (CA). This essay is concerned with the analysis
of the foundational concepts at work within Sen and Nussbaum’s CAs. Part One concerns the key
concepts of empowerment at work in Sen’s CA and has three goals. 1) Clarify Sen’s various
empowerment concepts. 2) Argue that Sen’s concept of Realize Agency Success is flawed. 3) Make
clear that empowerment in Sen’s approach can be helpfully understood in terms of agency and
capability set expansion. Part Two considers Nussbaum’s CA and the debate over whether it can
account for empowerment. I conclude that not only can Nussbaum’s CA account for empowerment,
but that the role of empowerment in both Sen’s and Nussbaum’s CAs can be understood in terms of
agency and capability set expansion. In other words, Sen and Nussbaum actually agree about
empowerment at the foundational level.
