Sammanfattning av Working paper 2006:9

The paper describes the Swedish wage distribution and how it correlates with worker mobility and plant-specific factors. It is well known that wage inequality has increased in Sweden since the mid-1980s. However, little evidence has so far been available as to whether this development reflects increased dispersion between plants, between individuals in the same plant, or both. We use a new linked employer-employee data set and discover that a trend rise in betweenplant
wage inequality account for the entire increase in wage dispersion. This pattern, which remains when we control for observable individual human capital characteristics, may reflect increased sorting of workers by skill levels and/or increased scope for rent sharing in local wage negotiations. Our discussion suggests that both factors may have become more important.
