Income Mobility and Inequality: Adult‐Level Measures From the Us Tax Data Since 1979
利用美国税收面板数据，研究发现收入流动性对1980年代以来年度不平等上升的解释程度在0到四分之三之间，结果对度量方法和样本选择高度敏感，强调敏感性分析的重要性。
A panel of tax returns shows that income mobility can explain between none and three‐quarters of the increase in annual inequality since the 1980s. These estimates are sensitive to different measures of inequality, income definitions, and sample restrictions—mostly due to different treatments of mean‐reverting income changes among those with temporarily low incomes. This range of results suggests that sensitivity analyses are crucial to understand the robustness of income inequality and mobility measures.
