Household Food Expenditures, Parental Time Allocation, and Childhood Overweight: An Integrated Two‐Stage Collective Model with an Empirical Application and Test
构建了一个两阶段集体家庭生产模型，分析家庭食品支出、父母时间分配与儿童超重的关系，并用数据检验了传统单一模型，发现政策含义有显著差异。
Abstract This article develops a two‐stage collective household production model for household food expenditures, parental time allocation, and childhood overweight. The model fills four gaps in the literature: (i) the “black box” treatment of intrahousehold decision making, (ii) exclusion of the child's decision input, (iii) exclusion of noneconomic variables, and (iv) absence of theory‐supported instrument identification. The traditional unitary household production model with children is a special case of the model developed. Using a unique data set, the unitary model is rejected. There are important differences in the policy implications to be drawn from both models based on the data set used.
