We study the effects of patriotism on tax compliance. If individuals feel a (random) patriotic warm glow from honest tax compliance, this has implications for optimal auditing and tax compliance. A higher expected warm glow reduces the government's optimal audit probability and yields higher tax...

Deterrence of illegal activities is frequently carried out by many atomistic auditors (tax auditors, law enforcement agents, etc.). Not much is known either normatively about the best way to incentivize atomistic auditors, nor positively about what these incentives actually look like in real...

Non-compliance of firms with tax regulations is a major constraint on state capacity in developing countries. We focus on an arguably under-appreciated dimension of non-compliance: under-reporting of wages by formal firms to evade payroll taxes. We develop a simple partial-equilibrium model of...

We study the consequences of leniency - reduced legal sanctions for wrongdoers who spontaneously self-report to law enforcers - on sequential, bilateral, illegal transactions such as corruption, manager-auditor collusion, or drug deals. It is known that leniency helps to deter illegal...

We review current methods for calculating fines against cartels in the US and EU, and simulate their deterrence effects under different assumptions on the legal and economic environment. It is likely that European fines have not had significant deterrence effects before leniency programs were...

During the transition from plan to market, managers and politicians succeeded in maintaining control of large parts of the stock of socialist physical capital. Despite the obvious importance of this phenomenon, there have been no efforts to model, measure and investigate this process...

We present a simple model to analyse law enforcement problems in transition economies. Law enforcement implies coordination problems and multiplicity of equilibria due to a law abidance and a fiscal externality. We analyse two institutional mechanisms for solving the coordination problem. A...

When penalties for first-time offenders are restricted, it is typically optimal for the lawmaker to overdeter repeat offenders. First-time offenders are then deterred not only by the (restricted) fine for a first offense, but also by the prospect of a large fine for a subsequent offense. Now...

A model of harassment bribes (paid for services one is entitled to) is developed and used to analyze the recent proposal to legalize paying bribes while increasing fines on accepting bribes. We explore performance as regards corruption deterrence and public service provision. A modified scheme,...

The success or failure of the fight against tax havens is the outcome of a coordination game between a tax haven and its potential investors. Key determinants are the costly international pressure and the haven country's revenue pool. The latter is determined endogenously by the decisions of...
