A key contention in economics is the discrepancy between micro and macro elasticities of labor supply with respect to marginal tax rates. We revisit this question, focusing on the role of dynamic returns to effort among top earners. We develop a new model of earnings responses to taxes in the...

We decompose changing gaps in life expectancy between rich and poor into differential changes in age-specific mortality rates and differences in "survivability". Declining age-specific mortality rates increases life expectancy, but the gain is small if the likelihood of living to this age is...

In the second half of the 2010s more than 100 countries--including all large offshore financial centers--started to automatically exchange bank information with foreign tax authorities. This informational big-bang marks a break with the situation of offshore bank secrecy that prevailed before....

This paper examines if active labor market programs help unemployed job seekers find jobs using a novel random caseworker instrumental variable (IV) design. Leveraging administrative data from Denmark, our identification strategy exploits that (i) job seekers are quasi-randomly assigned to...

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 survey the recent empirical literature on the effects of offshoring on wages, employment and displacement. We start with the measurement of offshoring, focusing on the use of imported inputs that could have been produced by the importing firm. We overview key theories related to offshoring...

We estimate how offshoring and exporting affect wages by skill type. Our data match the population of Danish workers to the universe of private-sector Danish firms, whose trade flows are broken down by product and origin and destination countries. Our data reveal new stylized facts about...

Using Danish administrative data, we estimate the impact of bequests on the level and inequality of wealth. We employ an event study design where we follow the distribution of wealth over time of people who are 45-50 years old, and divide them into treatment group and control group depending on...

This paper analyzes a randomized tax enforcement experiment in Denmark. In the base year, a stratified and representative sample of over 40,000 individual income tax filers was selected for the experiment. Half of the tax filers were randomly selected to be thoroughly audited, while the rest...

A large literature evaluating the welfare effects of taxation has examined the role of the labor supply elasticity, and has shown that the estimated welfare effects are highly sensitive to its size. A common feature of this literature is its exclusive focus on hours worked and the associated...
