Modelling Earnings Dynamics and Inequality: Foreign Workers and Inequality Trends in Luxembourg, 1988–2009
利用大规模行政数据，分析卢森堡20年间男性收入不平等趋势，发现总体不平等稳定但背后有复杂变化，外国工人贡献增加，收入不稳定性下降。
Summary The paper exploits large-scale administrative data to analyse trends in male earnings inequality in Luxembourg during 20 years of rapid economic growth, industrial redevelopment and massive inflow of foreign workers. A detailed error components model is estimated to identify persistent and transitory components of (the trends of) log-earnings variance and to disentangle the contributions to it of native, immigrant and cross-border workers. The model is flexible and allows for a high degree of individual, age, time and cohort heterogeneity. We observe a surprising stability in overall earnings inequality as a result of more complex underlying changes, with marked increases in persistent inequality (except among natives), a growing contribution of foreigners and a decrease in earnings instability (primarily for natives).
