Earnings Dynamics and Inequality among Canadian Men, 1976–1992: Evidence from Longitudinal Income Tax Records
利用加拿大纵向所得税记录，分解收入不平等增长为长期不平等和收入不稳定性两部分，发现两者均上升，并指出美国文献常用假设在加拿大数据中不成立。
Using an extraordinary database drawn from longitudinal income tax records, we decompose Canada's growth in earnings inequality into its persistent and transitory components. We find that the growth in earnings inequality reflects both an increase in long‐run inequality and an increase in earnings instability. The Canadian data strongly reject several restrictions commonly imposed in the U.S. literature, and they also suggest that imposing these evidently false restrictions may lead to distorted inferences about earnings dynamics and inequality trends.
