We show that the Roy model has more precise predictions about the self‐selection of migrants than previously realized. The same conditions that have been shown to result in positive or negative selection in terms of expected earnings also imply a stochastic dominance relationship between the...

We document the declining gap between the average earnings of women and men in Denmark from 1980 to 2010. The decline in the earnings gap is driven by increased labor force participation and in-creases in hours worked by women, and to a smaller extent by a decline in the gender wage gap. The gap...

Pregnancy conditions have been shown to matter for later economic success, but many threats to fetal development that have been identified are difficult to prevent. In this paper I study seasonal influenza, a preventable illness that comes around every year and causes strong inflammatory...

Family members tend to have similar labor market outcomes, but measuring the contribution of behavioral spillovers is difficult. To identify spillovers between brothers, we exploit Denmark's largest random assignment – of young men to 8 months of military service – where service status of...

This paper examines whether nutritional disruptions experienced during the stage of fetal development impair an individual's labor market productivity later in life. We consider intrauterine exposure to the month of Ramadan as a natural experiment that might cause shocks to the inflow of...

Increased job effort can raise productivity and income but put workers at increased risk of illness and injury. We combine Danish data on individuals' health with Danish matched worker-firm data to understand how rising exports affect individual workers' effort, injury, and illness. We find that...

We study how the skill distribution for an economy responds to changes in the skill premium induced by trade integration. Using administrative data for Denmark (1993- 2012) and Portugal (1993-2011), we conduct a two-step analysis. In the first step we predict the skill premium changes which are...

This paper examines the sources of differences in social mobility between the U.S. and Denmark. Measured by income mobility, Denmark is a more mobile society, but not when measured by educational mobility. There are pronounced nonlinearities in income and educational mobility in both countries....

In this paper we study the relevance and mechanics of consumption network effects. We use long panel data on the entire Danish population to construct a measure of consumption based on administrative tax records, and define the peer groups in terms of workplace, occupation, education, and age....

Using longitudinal data on the universe of workers in Denmark during the period 1991-2008 we track the labor market outcomes of low skilled natives in response to an exogenous inflow of low skilled immigrants. We innovate on previous identification strategies by considering immigrants...
