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...

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...

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...

This paper presents a simple agency model to explain why third-party income reporting by employers dramatically improves income tax enforcement. Modern firms have a large number of employees and carry out complex production tasks, which requires the use of accurate business records. Because such...

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...

We study wealth inequality in childhood using Danish wealth records from three decades. While teenagers have some earnings, we estimate that transfers account for at least 50 percent of wealth at age 18, and much more so for the rich children. Inheritance from grandparents does not appear...

This paper analyzes the optimal income tax treatment of couples. Each couple is modelled as a single rational economic agent supplying labor along two dimensions: primary and secondary earnings. We consider fully general joint income tax systems. Separate taxation is never optimal if social...

We link survey data on Danish people's perceived income positions and fairness views on inequality within various reference groups to administrative records on their reference groups, income histories, and life events. People are, on average, well- informed about the income levels of their...

What happens when immigrant girls are given increased opportunities to integrate into the workplace and society, but their parents value more traditional cultural outcomes? Building on Akerlof and Kranton’s identity framework (2000), we construct a simple game-theoretic model which shows how...

Using quasi-random assignment of criminal cases to judges, we estimate large incarceration spillovers in criminal and brother networks. When a defendant is sent to prison, there are 51 and 32 percentage point reductions in the probability his criminal network members and younger brothers will be...
