We study the impact of targeted high quality preschool over the life cycle and across generations, and examine its interaction with a health intervention during infancy. Using administrative data from Denmark together with variation in the timing of program implementation between 1933 and 1960,...

In this paper we develop a model capturing key features of the Roy model, a search model, compensating differentials, and human capital accumulation on-the-job. We establish which features of the model can be non-parametrically identified and which cannot. We estimate the model and use it to...

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....

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

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...

A unitarian model of family migration in which families may discount wives' private gains is used to derive testable predictions regarding the type of couples that select into migrating. The empirical tests show that gender neutral family migration cannot be rejected against the alternative of...

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...

The impact of imports from low-wage countries on domestic labor market outcomes has been a hotly debated issue for decades. The recent surge in imports from China has reignited this debate. Since the 1980s several developed economies have experienced contemporaneous increases in the volume of...

This paper uses administrative data to in detail document how the share of youths not in employment, education or training has evolved over time in the Scandinavian countries. We study both first- and second-generation immigrant youths as well as natives to explore whether the pattern differ...

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 socioeconomic status more generally....
