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 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 compare behavior in Weber's (2001) Dirty Faces Game with that in a modified version. The modifified version is designed to reduce the level of strategic uncertainty by ruling out some equilibria in weakly dominated strategies. We find that in the three-player version of the game reduced...

In this study we investigate the impact of competition on markets for non-durable goods where intertemporal price discrimination is possible. We develop a simple model of different potential scenarios for intertemporal price discrimination and implement it in a laboratory experiment. We compare...

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...

We focus on a relatively neglected area of the tax-compliance literature in economics, the behaviour of firms. We examine the impact of alternative audit rules on receipts from a tax on profits in the context of strategic interdependence of firms. In the market firms may compete in terms of...

We investigate experimentally if endogenous partnership formation can improve efficiency in social dilemma situations. Subjects play multiple two-player public goods games, where they can break up with their current partner after every fourth game. Subjects without a partner provide rankings of...

Weber (2001) uses the Dirty Faces Game to examine the depth of iterated rationality. Weber does not consider equilibria that contain weakly dominated actions. So he implicitly assumes that it is common knowledge that no one ever uses weakly dominated actions. We show that allowing for equilibria...
