Martha Nussbaum of the University of Chicago and author of Creating Capabilities talks with EconTalk host Russ Roberts about an alternative to GDP for measuring economic performance at the national level. She is a proponent of the capabilities approach that emphasizes how easily individuals can acquire skills and use them, as well as the capability to live long and enjoy life. Nussbaum argues that government policy should focus on creating capabilities rather than allowing them to emerge through individual choices and civil society.
