Using data on French male wage workers observed over 30 years, we estimate by random and fixed effect methods a wage equation with pervasive heterogeneity. Individual wage profiles are derived from a human capital investment model and described by a level, a slope and a curvature. Among others, our empirical application delivers original results on issues like the Mincer dip, and the time-varying correlations between wage growth and levels, or between initial wages and growth. Static and long-run inequality indices can easily be compared and decomposed into their multidimensional components.

生命周期中的异质性和工资不平等

我们使用30年来观察到的有关法国男性工资工人的数据，通过随机和固定效应方法估算了具有普遍异质性的工资方程。个人工资概况是根据人力资本投资模型得出的，并通过水平，斜率和曲率来描述。除其他外，我们的经验应用程序在诸如Mincer下降，工资增长与水平之间或初始工资与增长之间的时变相关性等问题上提供了原始结果。静态和长期不平等指数可以轻松地进行比较，并分解为多维要素。
