摘要：We utilize the latest household survey to document the trend of time allocation in China from 2008 to 2020. Firstly, we find, unlike many advanced economies, weekly market hours in China rise for three to six hours in the urban area when the real wage rate increases by 60 percent. Secondly, non-market hours decrease at the same magnitude in this period, highlighting the role of non-market hours in total labor supply. Thirdly, wage rate and market hours are strongly negatively correlated in cross sections. To reconcile these facts, we build a quantitative life cycle heterogeneous agent incomplete market model with home production and pay-as-you-go pension transfer to conduct an accounting. Quantitatively, we find rising wage uncertainty, changing demographic structures, and capital augmenting productivity growth in home production contribute to explaining rising market hours. The calibrated model can recover the observed empirical trend in market hours, non-market hours, and the correlation between market hours and wage rate reasonably well.
