Did earnings mobility change after minimum wage introduction? Evidence from parametric and semi‐nonparametric methods in Germany
研究了2011-2018年德国收入流动性的变化，使用参数和半非参数方法评估2015年最低工资引入对工资分布底部位置持续性的影响，发现流动性下降。
We analyze the evolution of earnings mobility in Germany between 2011 and 2018. We use transition matrices and parametric and semi-nonparametric copula models to assess the impact of the introduction of the national minimum wage on January 1, 2015, on individual positional persistence in the wage distribution. We find a drop in mobility at the bottom of the distribution. This is confirmed both by the parametric and the semi-nonparametric methods used. Prediction accuracy of the semi-nonparametric model is higher than that of the fully parametric model.
