We develop a moral hazard model with auditing where both the principal and the agent can influence the probability that the true state of nature is verified. This setting is widely applicable for situations where fraudulent reporting with costly state verification takes place. However, we use...

This paper re-examines the individual tax-evasion decision. The standard portfolio approach is used to explain why higher tax rates and a higher gross income induce more tax evasion. These empirical facts could not be explained simultaneously with thin the standard framework before. We show...

We present an experimental study on the wasted resources associated with tax evasion. This waste arises from taxpayers and tax authorities, investing costly effort in concealment, respectively detection, of tax evasion. We show that (socially inefficient) efforts depend positively on the...

This paper investigates multi-item moral hazard with auditing contests. 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...

We present an experimental study on the wasted resources associated with tax evasion. This waste arises from taxpayers and tax authorities investing costly effort in the concealment and detection of tax evasion. We show that these socially inefficient efforts - as well as the frequency of tax...

This paper re-examines the individual income tax evasion decision in the simple framework introduced by Allingham and Sandmo (1972), where the individual taxpayer decides how much of his income is invested in a safe asset (reported income) and in a risky asset (concealed income). These early...

We present a simple model of corporate tax evasion allowing for potentially bad governments that abuse their fiscal powers to extort monies from firms. Our model shows that the potential existence of extortionist governments provides incentives for corporate tax evasion and increases enforcement...
