Comparing Income Mobility in Germany and the United States Using Generalized Entropy Mobility Measures
基于广义熵流动性度量的渐近抽样分布，利用PSID-SOEP面板数据对德国和美国的收入流动性进行统计严谨的比较，发现德国税后收入流动性显著高于美国，并通过子样本分解揭示可能原因。
Based on a derivation of the asymptotic sampling distribution of the generalized entropy mobility measures, this paper provides a statistically rigorous analysis of income mobility in Germany and the United States using the panel data set PSID-SOEP equivalent data file. Several alternative measures of income aggregation, inequality measures, and groupings are considered to establish robustness. We find that, to a high degree of statistical confidence, post-government income mobility is much higher in Germany. Possible reasons for these findings are revealed through disaggregation of the samples by population subgroups. © 2001 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
