这篇文章考察了母亲的劳动力供应是否阻碍了家庭生产，重点是日本家庭在家中准备食物。虽然对家庭生产的实证研究通常使用时间使用数据进行，但我们使用扫描仪收集的数据，这些数据涵盖了超过10,000个家庭在3年内购买的日常商品。基于日常食物消费支出的构成，我们衡量有多少产品是在家里使用耗时的过程制造的，并检查耗时的家庭生产是否因母亲外出就业而受到阻碍。使用我们的扫描仪数据的面板结构控制家庭中未观察到的异质性，我们首先表明，母亲外出就业对家庭烹饪有负面影响。与没有工作的母亲相比，这种影响在所有经济阶层中都存在，特别是当母亲从事兼职工作时。其次，我们发现这种负面影响在低经济阶层更为明显。这一阶层的家庭在耗时的家庭烹饪方面表现出特别的减少，特别是当母亲们做兼职工作的时候。第三，较高阶层的负面影响较小，可以用较强的健康意识和对这一阶层中不太健康的产品的厌恶来解释。
This paper examines whether mothers’ labor supply discourages home production, focusing on food preparation at home in Japanese families. Although empirical studies on home production are usually conducted using time use data, we use data collected by scanners, which cover daily goods purchased by over 10,000 households over 3 years. Based on the composition of daily food expenditures for foods consumed, we measure how many products are made using time-consuming processes at home, and examine if time-consuming home production is discouraged by mothers’ employment away from home. Controlling for unobserved heterogeneity among households using the panel structure of our scanner data, we first show that mothers’ out-of-home employment has a negative effect on home cooking. This effect is shared across economic classes, particularly when mothers work part-time, as compared with non-working mothers. Second, we show that this negative effect is more apparent in the low economic class. Households in this class show a particular decrease in time-consuming home cooking, especially when the mothers work part-time. Third, the smaller negative effect among the higher class can be explained by stronger health-consciousness and aversion to less-healthy products in this class.
