In many settings, decision-makers' behavior is observed to vary based on seemingly arbitrary factors. Such framing effects cast doubt on the welfare conclusions drawn from revealed preference analysis. We relax the assumptions underlying that approach to accommodate settings in which framing...

We examine novel data on searches for capital-gains-tax-related information to determine when and how taxpayers acquire information. We find strong seasonal increases in information search around tax filing deadlines, suggesting that taxpayers seek information to comply with tax laws. Positive...

In 2008, the IRS initiated efforts to curb the use of offshore accounts to evade taxes. This paper uses administrative microdata to examine the impact of the enforcement efforts on taxpayers' reporting of offshore accounts and income. Enforcement caused approximately 60,000 individuals to...

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...

This paper shows how Danish administrative register data can be combined with survey data at the person level and be used to validate information collected in the survey. Register data are collected by automatic third party reporting and the potential errors associated with the two data sources...

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...
