Using longitudinal data for Norwegian children born in 1950, 1955, 1960 and 1965, we find a relatively high degree of earnings mobility. There is no tendency toward decreasing mobility over the cohorts. Conditioning on the position in the earnings distribution, the analysis indicates quite high mobility in the middle of the distribution and somewhat more persistence at the top and bottom. This approach also reveals increased mobility over time for sons, but a less clear picture for daughters.
