Third-party reporting and employers' tax withholding are powerful compliance mechanisms, as long as the employer and employee do not collude to evade. Using data from randomly assigned on-site audits among 2,462 Norwegian firms, we provide evidence of collusive tax evasion. We find that firms...

We run a large-scale natural field experiment to evaluate alternative strategies to enforce compliance with the law. The experiment varies the text of mailings sent to potential evaders of TV license fees. We find a strong alert effect of mailings, leading to a substantial increase in...

Governments increasingly use changes in tax rules to combat evasion. We develop a general approach to point-identify tax compliance along with supply and demand elasticities; identification requires data on prices and quantities before and after changes in tax enforcement and a demand or supply...

The ability of a tax authority to successfully collect taxes depends critically on both its relationship with the taxpayers and how strongly these taxpayers are committed to contributing to the common good. We present evidence on a new non-intrusive approach aimed at fostering the commitment to...

We conducted a randomised controlled trial in Indonesia to evaluate the effect of three intervention letters on tax penalty compliance behaviour. Over 10,000 individual taxpayers are randomly assigned to receive either a deterrence, information, or simplification letter, or no letter. Our...

Parents make important choices for their children in many areas of life, yet the empirical literature on this topic is scarce. We study parents’ competitiveness choices for their children by combining two large-scale artefactual field experiments with high-quality longitudinal administrative...

The Norwegian Tax Administration operated multi-year random audits of personal income tax returns. We exploit this exceptional randomized setup to estimate the effects of tax audits on future compliance explicitly distinguishing between dynamic responses of compliant and noncompliant audited...

Edwards and Ogilvie (2008) dispute the empirical basis for the view (Greif, e.g., 1989, 1994, 2006) that multilateral reputation mechanism mitigated agency problems among the eleventh-century Maghribi traders. They assert that the relations among merchants and agents were law-based. This paper...

The deterrent effect of law enforcement rests on the link between the actual and the perceived detection risk. We study the role of word of mouth for this linkage. Our approach makes use of micro data on compliance with TV license fees allowing us to distinguish between households who have been...
