The consumption of a set of diverse medical services is analysed in an
effort to determine the sources of high utilization by women. Unlike
previous studies of gender and the demand for medical services, the ra
nge of services investigated allows us to draw conclusions about the i
nfluence of physicians as agents. We use a modified version of the alm
ost-ideal demand model in the empirical analysis which, unlike the dou
ble-log, quadratic, or linear demand models, is consistent with constr
aints imposed by economic theory. Through decomposition of the varianc
e, it was found that if women reported the same series of health indic
ators as men, their use of most services would fall below that of men.
