A country's gross domestic product counts a restaurant meal, a paid babysitter and a nursing-home stay as economic production. It does not count the equivalent unpaid work, a parent's meal cooked at home, a grandmother's childcare, a daughter's care for an aging parent, even though the labor and the value produced are functionally the same. Nancy Folbre's research, most fully set out in her 1994 book Who Pays for the Kids? Gender and the Structures of Constraint, made the argument that this omission is not a neutral accounting convenience but a structural feature of how economics has defined its own subject matter, one that happens to make the overwhelmingly female labor of care invisible to the discipline that studies production.
Folbre's account goes further than pointing out an omission. She argues that unpaid care work functions as a kind of tax, paid disproportionately by women, that subsidizes market production by raising the next generation of workers at private rather than social cost, and that markets, left alone, will systematically undervalue and under-provide care because its benefits are diffuse and long-term while its costs fall immediately on the person providing it.
The 1992 founding of the International Association for Feminist Economics gave this line of research an organized field and its own journal, Feminist Economics, rather than leaving it scattered across labor economics, family economics and sociology. Folbre's own later work, as director of the Program on Gender and Care Work at the University of Massachusetts Amherst's Political Economy Research Institute, has pushed statistical agencies toward satellite accounts that estimate the monetary value of unpaid care, an attempt to make visible in the numbers what the theory had already shown was invisible only by choice of definition.
