与1958年出生的同龄人相比，1970年出生的同龄人的家庭收入与儿子的收入关系更密切。这一结果与基于社会阶层的调查结果形成鲜明对比;这一结果的代际流动性被认为是不变的。我们的目的是探讨这种分歧的原因。我们得出一个正式的框架，涉及流动性衡量的家庭收入或收入的流动性衡量的社会阶层。在这个框架的基础上，我们测试了几个替代假设，以解释趋势之间的差异。我们发现证据的增加，代际持久性的永久性组成部分的收入是无关的社会阶层。我们拒绝的假设，观察到的收入流动性下降是1958年队列的永久家庭收入的测量不佳的结果。
Family income is found to be more closely related to sons earnings for a cohort born in 1970 compared with a cohort born in 1958. This result is in stark contrast with the finding on the basis of social class; intergenerational mobility for this outcome is found to be unchanged. Our aim here is to explore the reason for this divergence. We derive a formal framework which relates mobility as measured by family income or earnings to mobility as measured by social class. Building on this framework we then test several alternative hypotheses to explain the difference between the trends. We find evidence of an increase in the intergenerational persistence of the permanent component of income that is unrelated to social class. We reject the hypothesis that the observed decline in income mobility is a consequence of the poor measurement of permanent family income in the 1958 cohort.
