Socioeconomic (SES) gaps in academic achievement are well documented. We show that a very similar gap exists with respect to genetic differences measured by a polygenic score (PGS) for educational attainment. The genetic gap increases during elementary school, but only among the low SES...

It is widely recognised that genetics and family investments both matter for children's development. However, the two are often treated as separate factors where the higher importance of one implies a lesser role of the other. In this paper, we challenge this view and show that genes and family...

We study how children's socio-emotional skills and well-being in adolescence are affected by an increase in the duration of parental care during infancy. Exploiting a Danish reform that extended paid parental leave in 2002 and effectively delayed children's entry into formal out-of-home care, we...

In this paper we study effects of mass layoffs on parents and their children in the aftermath of the Great Recession using staggered difference-in-differences (DiD). We exploit quasi-experimental variation in announcements of mass layoffs in Danish firms in 2008-2019. We document that parents...

We perform a comprehensive analysis of the stepping-stone effect of temporary agency employment on unemployed workers. Using the timing-of-events approach, we not only investigate whether agency employment is a bridge into regular employment but also analyze its effect on post-unemployment wages...

We examine rational learning among expert chess players and how they update their beliefs in repeated games with the same opponent. We present a model that explains how equilibrium play is affected when players change their choice of strategy when receiving additional information from each...

Randomized experiments provide policy relevant treatment effects if there are no spillovers between participants and nonparticipants. We show that this assumption is violated for a Danish activation program for unemployed workers. Using a difference-in-difference model we show that the...

We investigate whether agency employment is a bridge into regular employment for immigrants to Denmark using the timing-of-events approach. We provide evidence of large positive in-treatment effects, particularly for non-western immigrants and immigrants arriving during childhood. Post-treatment...

Active labour market policies (ALMPs) may play an important role in preventing an increase in long-term unemployment following the Great Recession. We consider this issue for Denmark, a country relying extensively on this instrument. We present evidence on the effectiveness of ALMPs as a way of...

This paper investigates whether the stepping-stone effect of temporary agency employment varies over the business cycle. Using German administrative data for the period 1985-2012 and an estimation framework based on the timing-of-events model, we estimate in-treatment and post-treatment effects...
