TY - JOUR T1 - Heterogeneous Income Profiles and Lifecycle Bias in Intergenerational Mobility Estimation JF - Journal of Human Resources JO - J Hum Resour SP - 239 LP - 268 DO - 10.3368/jhr.51.1.239 VL - 51 IS - 1 AU - Martin Nybom AU - Jan Stuhler Y1 - 2016/01/01 UR - http://jhr.uwpress.org/content/51/1/239.abstract N2 - Using short snapshots of income in intergenerational mobility estimation causes “lifecycle bias” if the snapshots cannot mimic lifetime outcomes. We use uniquely long series of Swedish income data to show that this bias is large and to examine current strategies to reduce it. We confirm that lifecycle bias is smallest when incomes are measured around midlife, a central implication from a widely adopted generalization of the classical errors-in-variables model. However, the model cannot predict the ideal age of measurement or eliminate lifecycle bias at other ages. We illustrate how extensions of this model can reduce the bias further. ER -
