The autonomy perspective of housework time predicts that wives' housework time falls steadily as their earnings rise, because wives use additional financial resources to outsource or forego time in housework. We argue, however, that wives' ability to reduce their housework varies by household task. That is, we expect that increases in wives' earnings will allow them to forego or outsource some tasks, but not others. As a result, we hypothesize more rapid declines in wives' housework time for low-earning wives as their earnings increase than for high-earning wives who have already stopped performing household tasks that are the easiest and cheapest to outsource or forego. Using fixed-effects models and data from the Panel Study of Income Dynamics, we find considerable support for our hypothesis. We further conclude that past evidence that wives who out-earn their husbands spend additional time in housework to compensate for their gender-deviant success in the labor market is due to the failure to account for the non-linear relationship between wives' absolute earnings and their housework time.
家务时间的自主性观点预测,随着妻子收入的增加,妻子的家务时间会稳步下降,因为妻子会利用额外的财务资源来外包或放弃家务时间。然而,我们认为,妻子减少家务劳动的能力因家庭任务而异。也就是说,我们预计妻子收入的增加将使她们能够放弃或外包某些任务,但不是其他任务。因此,我们假设,随着收入较低的妻子收入的增加,她们的家务时间下降速度会比那些已经不再从事最容易和最便宜的外包或放弃的家务劳动的高收入妻子更快。利用固定效应模型和来自收入动态面板研究的数据,我们的假设得到了相当多的支持。我们进一步得出结论,过去有证据表明,丈夫收入超过妻子的妻子会花更多的时间在家务上,以弥补她们在劳动力市场上性别偏差的成功,这是由于没有考虑到妻子的绝对收入与其家务时间之间的非线性关系。
