  How does women's obedience to traditional gender roles affect their labour
outcomes? To investigate on this question, we employ discontinuity tests and
fixed effect regressions with time lag to measure how married women in China
diminish their labour outcomes so as to maintain the bread-winning status of
their husbands. In the first half of this research, our discontinuity test
exhibits a missing mass of married women who just out-earn their husbands,
which is interpreted as an evidence showing that these females diminish their
earnings under the influence of gender norms. In the second half, we use fixed
effect regressions with time lag to assess the change of a female's future
labour outcomes if she currently earns more than her husband. Our results
suggest that women's future labour participation decisions (whether they still
join the workforce) are unaffected, but their yearly incomes and weekly working
hours will be reduced in the future. Lastly, heterogeneous studies are
conducted, showing that low-income and less educated married women are more
susceptible to the influence of gender norms.
