This paper is concerned with the relationship between class size and the student outcome length of time in post-compulsory schooling. Research on this topic has been problematic partly because omitted unobservables, like parents' incomes and education levels, are likely to be correlated with...

We investigate the stages of childhood at which parental job loss is most consequential for their child's education. Using Danish administrative data linking parents experiencing plant closures to their children, we compare end-of-school outcomes to matched peers and to closures hitting after...

We propose a twin family model linking twins with their spouses and children to quantify the relative importance of genetic and environmental factors in explaining the variance of socio-economic outcomes. Using data from the Danish Twins Registry and population registers, we test and relax the...

This paper gives a comprehensive picture of job and worker flows for the entire Danish economy. We exploit a unique central administrative register encompassing all employees of all workplaces across all sectors throughout two business cycles. This enables us to broaden the focus of the previous...

We investigate the relationship between life-cycle wages and flexicurity in Denmark. We separate permanent from transitory wages and characterise flexicurity using membership of unemployment insurance funds. We find that flexicurity is associated with lower wage growth heterogeneity over the...

Military conscription implicitly taxes draftees. Those who would have volunteered at the market wage may be forced to serve for lower wages, and those with higher opportunity costs may be forced to serve regardless, yet little is known about the distribution of this burden. We exploit the Danish...

Correlations between parent and child earnings reflect intergenerational mobility and, more broadly, correlations between siblings’ earnings reflect shared community and family background. These earnings relationships capture important aspects of relations in socio-economic status more...

We model the correlations of brothers' earnings isolating the effect of fathers' earnings from additional residual influences shared between brothers. We separate the two effects by analysing sibling correlations and intergenerational correlations jointly within a unified framework. Our...

Correlations between the earnings of siblings reflect shared family and community background, but evidence is mixed on the relative magnitudes of these influences. We estimate long run earnings correlations between brothers, school mates and teenage neighbors jointly in a unified framework....

Using longitudinal data based on administrative registers for the population of Danish men we develop a model which accounts for the joint earnings dynamics of siblings and youth community peers. We are the first to decompose the sibling correlation of permanent earnings into family and...
