Change in intergenerational economic mobility in Norway: conventional versus joint classifications of economic origin

Studies of mobility within both sociology and economics most commonly use a conventional classification of social or economic origin, based on the position of the father only. The questions raised in the paper is whether there has been a trend towards more economic mobility, and whether conclusions about change based on a joint classification of both mother and father differ from those based on conventional classifications. These questions are addressed on the basis of register data on the earnings of the total Norwegian population of mothers, fathers and children from 1967 and onwards. The analyses focus on the earnings of the cohorts born between 1955 and 1970, and their earnings at the age of 34–35. The results do not support the argument in previous research that intergenerational economic mobility has increased in Norway. Moreover, the results based on a conventional approach differ from those based on a joint classification including the earnings of both mother and father. Using the latter approach there is no indication of a trend towards greater openness.
