We investigate long-run earnings responses to taxes in the presence of dynamic returns to effort. First, we develop a theoretical model of earnings determination with dynamic returns to effort. In this model, earnings responses are delayed and mediated by job switches. Second, using...

Using administrative data on wealth, firm ownership structure, and migration in Sweden and Denmark, we document international migration patterns among the very wealthy, their impact on the economy, and how they respond to wealth taxation. We show that more than 20% of taxpayers liable to pay...

In this paper I investigate the nature of optimization frictions by studying the labor market of Danish students. This particular labor market is an interesting case study as it features a range of special institutional settings that affect students' incentive to earn income and comparing...

We revisit the identification of behavioral responses to tax reforms and develop a new approach that allows for graphical validation of identifying assumptions and representation of treatment effects. Considering typical tax reforms, such as a reduction in the top income tax, we show that the...

Using Danish administrative data, I investigate the magnitude and nature of optimization frictions in the labor market of Danish students. Danish students face a unique institutional setting that makes it possible to distinguish between different types of frictions and estimate their effect on...

We revisit the identification of behavioral responses to tax reforms and develop a new approach that allows for graphical validation of identifying assumptions and representation of treatment effects. Considering typical tax reforms, such as a reduction in the top income tax, we show that the...

We study the design of parental leave systems through the lens of an estimated model of parents' joint willingness to pay for parental leave. We estimate the model using Danish register data on almost 200,000 births combined with sharp variation in economic incentives created by the parental...

We study the design of parental leave systems through the lens of an estimated model of parents’ joint willingness to pay for parental leave. We estimate the model using Danish register data on almost 200,000 births combined with sharp variation in economic incentives created by the parental...

We show how tax kinks can be used to estimate the marginal propensity to consume (MPC). Tax kinks create discrete changes in the relationship between taxable income and disposable income, which – under a set of testable assumptions – enables causal identification of the spending response to...
