Baby Booming Inequality? Demographic Change and Inequality in Norway, 1967-2004 .

Ingvild Alm as, Tarjei Havnes and Magne Mogstad

We demonstrate how age-adjusted inequality measures can be used to evaluate
whether changes in inequality over time are due to changes in the age-structure. In
particular, we explore the hypothesis that the substantial rise in earnings inequality
since the early 1980s is driven by the large baby boom cohorts approaching the peak
of the age{earnings pro le. Using administrative data on earnings for every male
Norwegian over the period 1967{2004, we nd that the impact of age adjustments
on the trend in inequality is highly sensitive to the method used: While the most
widely used age-adjusted inequality measure indicates that the rise in inequality in
the 1980s and 1990s is indeed driven partly by the baby boom, a new and improved
age-adjusted measure indicates the opposite, namely that the rise in inequality was
even larger than what the inequality measures unadjusted for age reveal.
