Employing econometric methods for univariate time series, this paper investigates the empirical validity of assuming a unit root in individuals' labor-income processes. Using a Swedish register-based longitudinal dataset which allows us to follow a cohort of workers from 1968 to 2005, we are...

Using a large Swedish longitudinal database for the period 1982–2005, I estimate and compare within-group inequality in persistent and transitory earnings among men with high-school and college degrees. Analyses of inequality over the life cycle reveal that experience-variance profiles of...
