One of the authors makes the paper available for free at his Web page: Michael Burda, Daniel S. Hamermesh, and Philippe Weil, "Total Work, Gender and Social Norms," NBER Working Paper 13000, 2007, <http://www.eco.utexas.edu/faculty/Hamermesh/IsoWorkToGo307.pdf>. There is a major problem in the authors' assumptions. On page 2, they declare:
We count as household production those activities
that satisfy the third-party rule (Reid, 1934) that
substituting market goods and services for one's own
time is possible. Such activities may be enjoyable
(as may be work in the market), even at the margin;
but they still have _the common characteristic that we
could pay somebody to perform them for us and we
are not paid for performing them_. We define total
work as the sum of time spent in market work and
household production. (emphasis added)
That's an assumption that is bound to underestimate women's work hours, for a lot of work that goes into "household production," especially of the sort that is more often done by women than men, is the kind of work for which there is no market substitute (e.g., taking children to doctors' offices). Based on this anti-feminist assumption, they "discover" this "fact": "Men enjoy more leisure, women spend more time in tertiary activities" (p. 5). What are "tertiary activities"? "[T]hose things that we cannot pay other people to do for us but that we must do at least some of" (p. 3), precisely the sort of activities that make home what it is that women tend to perform because men don't perform them and there are no market substitutes for them. :-0
