在家庭生产模型中,存在着市场部门与家庭部门之间的劳动替代,这就提高了模型解释现实经济的能力.如果发生家庭生产率冲击,且这种冲击与市场生产率不完全相关,那么随着家庭生产率的相对变化改变了市场部门既定工资的工人愿意提供的劳动量,劳动供给将会发生变化,这就降低了市场生产率与工作时数之间的相关性. In the family production model, there is a labor substitution between the market sector and the household sector, which increases the ability of the model to explain the real economy.If family productivity shocks occur that are not completely related to market productivity, The relative change in household productivity has changed the amount of labor that workers in established markets in the region are willing to provide, and labor supply will change, reducing the correlation between market productivity and hours of work.
