内容简介：We document the trend in time allocation in China from 2008 to 2024, utilizing the latest available time-use survey data in China. In contrast to recent empirical evidence from Bick et al. (2018) and Boppart and Krusell (2020), we find that market hours per person increased by 3 to 6 hours per week in urban areas of China, accompanied by a 60 percent increase in the wage rate over the same period. However, wage rates and market hours are strongly negatively correlated in the cross-sections. Meanwhile, non-market hours per person declined sharply by the same magnitude. To reconcile these facts, we build a quantitative life-cycle heterogeneous- agent incomplete-market model with home production and a pay-as-you-go pension transfer to conduct an accounting. Quantitatively, we find that rising income uncertainty, changing demographic structures, and capital-augmenting productivity growth in home production help explain the rise in market hours. The calibrated model can reasonably well recover the ob- served empirical trend. Our results suggest that it is crucial to account for non-market hours, demographic structures, and incomplete markets when analyzing the long-run trend in labor supply.
