内容摘要：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 China’s urban areas, 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 observed empirical trend. Our results suggest that analyzing the long-run trend in labor supply requires accounting for non-market hours, demographic structures, and incomplete markets.
