This paper explores the hypothesis that gender wage differentials arise from the interaction between the intra-household allocation of labour and the contractual relation between firms and workers in the presence of private information on workers? labour market attachment. In our model, if firms believe women to be less attached to market work than men, they will offer them labour contracts with lower earnings and lower hours even in the absence of gender differences in productivity. This implies that it is efficient for wives to allocate more time to home production. Hence, women will be less attached to market work and firms? expectations are confirmed. If firms instead believe that labour market attachment is the same across genders, they will offer the same labour contracts to male and female workers. Then, the efficient intra-household allocation of labour will not be related to gender. It is statistical discrimination that determines gender differentials in the first type of equilibrium. Given that firms may use gender as a screening device, discrimination actually reduces the incentive problem for firms, eliminating adverse selection. Additionally, our model predicts that, in equilibria with female discrimination, gender earning gaps should be higher in industries/occupations in which the incentive problem is more severe. We use Census data for the year 2000 to show that this is the case.
