This paper investigates multi-item moral hazard with auditing contests.s Although the presented model is widely applicable, we choose tax evasion as an exemplary application. We introduce a tax-evasion model where tax authority and taxpayer invest in detection and concealment. The taxpayers have...

In this paper we consider amoral taxpayers who access amoral tax preparers in order to receive help in evading taxes. Taxpayers are aware of having a biased perception of the audit probability, but are unable to correct such bias without the help of a tax preparer. The market for tax...

We characterize equilibria of an income reporting game with bounded returns and no commitment where detected tax evaders are charged the maximally feasible amount. Introducing partial commitment to punishment relief eliminates multiplicity of equilibria. We identify a unique limit equilibrium...

We examine the optimal auditing problem of a tax authority when taxpayers can choose both to evade and avoid. For a convex penalty function the incentive-compatibility constraints may bind for the richest taxpayer and at a positive level of both evasion and avoidance. The audit function is...

A robust prediction from the tax evasion literature is that optimal auditing induces a regressive bias in e¤ective tax rates compared to statutory rates. If correct, this will have important distributional consequences. Nevertheless, the regressive bias hypothesis has never been tested...
