Using a longitudinal dataset built merging administrative and survey data, we contribute to the literature on intergenerational inequality providing the first estimate of the intergenerational earnings elasticity (IGE) in Italy based on actual father–son pairs, taking into account issues related to measurement biases and comparing the size of the lifecycle bias when sons are selected by age or by potential experience (i.e. the number of years since the end of their studies). Our findings confirm that Italy is a low‐mobility country. In our baseline estimate, when sons are observed 6 years after the end of their studies, the IGE is approximately 0.41 and is robust to various measures of fathers’ lifetime earnings. However, our results might be downward biased by the young age of sons. To measure the lifecycle bias and correct IGE estimates, we run the ‘forward regression’ of yearly earnings on lifetime earnings on a sample of workers followed for 30 years. We find that selecting sons by potential experience rather than by age reduces the lifecycle bias at young ages and the ‘corrected’ IGE is 0.48. The picture of Italy as a low‐mobility country is also confirmed when we measure the intergenerational association through the rank–rank slope.

意大利实际的父子对之间的代际收入持续存在，解释了生命周期和衰减偏差

通过使用合并行政和调查数据的纵向数据集，我们为代际不平等问题的文献做出了贡献，提供了基于实际父子对的意大利代际收入弹性（IGE）的第一估计，并考虑了与衡量偏差和比较按年龄或潜在经验（即自研究结束以来的年限）选择儿子时的生命周期偏差的大小。我们的发现证实了意大利是一个交通不便的国家。根据我们的基准估计，当研究结束后的6年观察到儿子时，IGE约为0.41，并且对父亲一生的收入的各种衡量指标均很可靠。但是，我们的结果可能由于儿子的年龄偏低而下降。为了衡量生命周期偏差并纠正IGE估算，我们对追踪了30年的工人样本的终身收入进行了年度收入的“正向回归”。我们发现，根据潜在的经验而不是年龄选择儿子可以减少年轻时的生命周期偏差，“校正后”的IGE为0.48。当我们通过等级倾斜度测量代际关联时，也证实了意大利作为低机动性国家的情况。
