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.
