We document that the first leak of customer information from a tax haven bank caused a significant decrease in the market value of Swiss banks known to be assisting with tax evasion and that the decrease was largest for the banks most strongly involved. These findings suggest that markets...

This paper studies how imposing norms on contribution behavior affects individuals' intrinsic motivation. We consider an urban area in Germany where the Catholic Church collects a local church levy as a charitable donation, despite the fact that the levy is legally a tax. In cooperation with the...

We explore cheating behaviours in a die roll task in response to information about tax malpractice in Italy using a survey experiment on a representative sample of the Italian population. We thus generalise laboratory findings on conditional behaviours (cooperation, cheating) to uncover their...

This paper derives a government's optimal tax audit policy when taxpayers hold different beliefs about the likelihood of a tax audit. When audits are inexpensive, differences in perceived audit risk lead to stricter optimal auditing in equilibrium. If audits are relatively costly, heterogeneity...

This paper derives the optimal financial contract when an entrepreneur can evade taxes in a model of costly state verification. In contrast to previous literature on costly state verification and financial contracting, we find that standard debt contracts are not optimal when tax evasion is...

This paper analyzes corporate tax evasion in a principal-agent model with multitasking. A firm-owner hires a specialist tax manager who chooses the quantity as well as the quality of tax evasion. Higher quality is a form of self-insurance and lowers the firm's expected fine for tax evasion. In...

We provide evidence on both innovative as well as known behavioral strategies aimed at improving tax compliance, using a unified environment of two large correspondence experiments (N=82,599 and N=51,142) with potential TV-fees evaders in the Czech Republic. We (i) simplify the original letter...

This paper studies the role of beliefs about how own appearance and performance affect the subjective probability of being audited in a compliance situation, e.g. at customs. In an experiment in which underreporting has a higher expected payoff than truthful reporting we find an increase in...

In his David R. Tillinghast Lecture given at NYU in 1998, H. David Rosenbloom presented the tax world with a critical view as to the existence of an “international tax regime”. Has the world changed since? On the one hand there is a strong move towards international tax coordination,...

The question of why and how to tax the digitalized economy has been at the top of the international tax policy debate since the inception of the BEPS Action Plan in 2013. Over the years, a number of approaches have been discussed, including far-reaching proposals to fully or partially...
