It is career day at Luke’s school, and the teacher asks Claire to speak about her job as a stay at home mom. She points out that she actually has a lot of different jobs as a stay-at-home-mom. The household production model assumes that agents decide between working at paid work or working at home and producing things that they could have bought with income. Both yield some level of utility, but some partners will specialize in household production depending on the relative wages of the other partner.
One of the downsides of specializing in household labor is that people lose specific and general human capital associated with market work. While Claire would like to go back to work, it is hard to find a job after you have been out of the labor force for 15 years, mainly because everyone who didn’t drop out would have continued learning new skills. In labor economics, this is known as The Mommy Track.
