We show with theory and simulations that even using a 30-year income average can result in a small positive spurious … grandfather coefficient estimate. We further propose an IV approach, showing that it is not susceptible to this spillover bias in …

The first order … reveals an intuitive formula for the remaining second order bias which is useful in empirical analyses.
