In a novel approach to model the demand for the children's screen time as the result of a parent's optimal labor-leisure choice, the study used a simple model of parental utility maximization subject to the money and time budget constraints to derive Marshallian parental demand functions for two types of child upbringing activities: time-intensive (violin lesson) and time-saving (video games). After the Slutsky decomposition, parental demand for children's screen time was shown to be similar to a Giffen good. Using the National Longitudinal Survey of Youth 1979 and Adolescent Brain Cognitive Development data, the wage equation was first estimated based on Heckman’s two-step correction procedure. Then, the total effect of an increase in wage rate on the parental demand for screen time was empirically decomposed into the substitution effect and the income effect. The study findings indicate that the substitution effect is positive, the income effect is negative, and the negative income effect dominates the substitution effect. We add to the existing literature by showing that the empirical findings in the public health and psychology literature can be reconciled with the theoretical predictions of the standard economic labor-leisure trade-off paradigm.

在一种将孩子的屏幕时间需求建模为父母最佳劳动-休闲选择结果的新方法中，该研究使用受金钱和时间预算约束的父母效用最大化的简单模型来导出马歇尔父母需求函数两种类型的儿童养育活动：时间密集型（小提琴课）和节省时间（电子游戏）。在斯卢茨基分解之后，父母对孩子屏幕时间的需求被证明类似于吉芬商品。使用 1979 年全国青年纵向调查和青少年大脑认知发展数据，首先根据赫克曼的两步校正程序估算工资方程。然后，工资率增加对父母对屏幕时间的需求的总效应在经验上被分解为替代效应和收入效应。研究结果表明，替代效应为正，收入效应为负，负收入效应主导替代效应。我们通过表明公共卫生和心理学文献中的实证研究结果可以与标准经济劳动-休闲权衡范式的理论预测相一致来补充现有文献。
