This paper provides evidence of evasion in the context of a widely used commuter tax allowance, and explores evasion spillovers as a determinant of the individual compliance decision. For this purpose, we exploit discontinuities in the commuter allowance scheme and employ a research design...

We investigate the effects of an institutional mechanism that incentivizes tax payers to blow the whistle on collusive corruption and tax compliance. We do this through a leniency program. In our experiment we nest collusive corruption within a tax evasion framework. We not only study the effect...

Back in 2013, the Automatic Exchange of Information (AEOI) was endorsed as the prevailing universal solution to fight cross-border tax evasion. In this regard, the OECD launched a global standard for the AEOI, the Common Reporting Standard (CRS). Currently, around 100 jurisdictions have...

In markets where transactions are governed by contractual incompleteness, revealed intentions to evade taxes may affect market performance. We experimentally examine the impact of tax evasion attempts on the performance of credence goods markets, where contractual incompleteness results from...

The basic deterrence model of tax evasion is described, its main predictions are derived and limitations and flexibility are outlined. Further, the model is interpreted in light of some key institutional features characterising tax enforcement in OECD countries. Throughout the survey, findings...

This contribution surveys theoretical analyses of tax evasion by firms. It uses a simple model in which the firm determines economic activity and the under-declaration of the tax base to integrate various approaches into a coherent analytical framework. Initially, the chapter characterises the...

We study the effect of the first global multilateral standard for the automatic exchange of information (AEOI), the so called Common Reporting Standard (CRS), on cross border tax evasion. Employing newly available bilateral data on cross-border deposits, we find that the CRS induced a reduction...

If an additional competitor reduces output per firm in a homogenous Cournot-oligopoly, market entry will be excessive. Taxes can correct the so-called business stealing externality. We investigate how evading a tax on operating profits affects the excessive entry prediction. Tax evasion raises...
