This paper explores the implications of the difference between the Occ
upational distribution for males and females in a joint model determin
ing earnings and occupation. The male/female wage differential is eval
uated for a number of broad occupational classifications. This is foll
owed by an evaluation of the role and relative importance of inter-occ
upational and intra-occupational effects as contributors to the overal
l male/female wage differential. The main conclusion following from th
e econometric results is that intra-occupational effects dominate. Thu
s, policies which attempt to address the gender wage differential by r
e-allocation of labour across occupations are unlikely to solve the pr
oblem.
