Data from time diaries kept by parents in two-parent, two-child famili
es in four states in 1977 and 1978 were used to examine time shared by
parents and children, as well as parent solitary rimes, in a number o
f household activities. The analysis focuses on how the mother's emplo
yment time affects shared parent-child time and whether the rime was s
ex-typed. In addition, a weak rest for whether parent-child shared tim
e stimulates children's human capital development;was devised and the
hypothesis confirmed. Mothers who spent more time in market work share
d less traditionally defined child-care time, but only with the older
child. In contrast, as a mother's time in market work increased, paren
t-child shared housework and shared leisure time increased, Household
activities shared by the parent and the child were sex-typed. Mothers
tended to share more time with daughters in meal preparation and famil
y-care activities, and fathers tended to share more time with their so
ns in activities involving the home, yard, car and pet maintenance and
in shopping activities.
