This paper analyzes the role of network externalities and expectations about them in the formulation of trade policy. Their effects are studied in duopoly situations when products are compatible and when they are incompatible and when multimarket effects are possible. Network externalities and...

This paper develops a model of international competition in an oligopoly characterized by strong learning effects. The model is quantified by calibrating its parameters to reproduce the US-Japanese rivalry in 16K R.A.Ms from 1978-1983. We then ask the following question: how much did the...

We document the consequences of losing a job across countries using a harmonized research design. Workers in Denmark and Sweden experience the lowest earnings declines following job displacement, while workers in Italy, Spain, and Portugal experience losses three times as high. French and...

We evaluate the effect on newly arrived refugees' employment of a policy, introduced in Denmark in 2013, that matched refugees to occupations with local labor shortages after basic training for those jobs. Leveraging the staggered roll-out across municipalities, we find that the policy increased...

We use rich administrative data from Denmark to assess medical theories that autism spectrum disorder (ASD) is a heritable condition transmitted through underlying parental skills. Positing that occupational choices reflect skills, we create two separate occupation-based skill measures and find...

Focusing on bipolar disorder (BD), we investigate the link between mental health, creativity, and wealth. Analyzing population data for Denmark, we find that people with BD are more likely to be musicians, but less likely to hold other creative jobs than the population. Healthy siblings of...

This paper investigates the career effects of mental health, focusing on depression, schizophrenia, and bipolar disorder (BD). Individual-level registry data from Denmark show that these disorders carry large earnings penalties, ranging from 34 percent for depression and 38 percent for BD to 74...

The paper analyzes consumption decisions of retired workers, using Danish register data. A major puzzle, which motivates much of the analysis below, is that wealth actually increases for a large fraction of the people in our data. One would expect that wealth accumulated before retirement would...
