L ow tax incomes and the large size of the government in Iran lead into budget deficit, which increases the inflation rate. It also causes economic instability and fluctuations in inflation, leading to tax non-compliance and the transfer of people to the informal economy. Therefore, considering the variables of financial discipline and behavioral factors, this research examines the e...

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 multiple potential income sources and are heterogeneous with respect to their evasion scruples. The t...

BACKGROUND Decades of research have produced overwhelming evidence that tobacco taxes reduce tobacco use and increase government tax revenue. The magnitude and effectiveness of taxes in reducing tobacco use provide an incentive for tobacco users, manufacturers and others, most notably criminal networks, to devise ways to avoid or evade tobacco taxes. Consequently, tobacco tax avoidance and tax ...

Tax evasion analysis is typically based on an expected utility theory (EUT) framework. However, this leads to several qualitative and quantitative puzzles. Given actual probabilities of audit and penalty rates the return on evasion ranges from 91-98 percent. So why don’t most of us evade? Furthermore, an EUT based analysis predicts that we should evade less as the tax rate increases (Yitzhaki p...

753 National Tax Journal Vol. LII, No. 4 Abstract While obligatory advance tax payments do not interfere with the taxpayer’s evasion decision under expected utility theory, they do affect the decision to evade under prospect theory. The present paper applies prospect theory to a simple model of tax evasion, exploring the role that advance tax payments may play in enforcing tax laws. The paper d...

Tax evasion has been mainly studied as a problem of choice under uncertainty like any portfolio manager, the taxpayer has to allocate her/his fixed gross income between two assets: a risky asset, tax evasion, and a safe asset (with a zero return), tax payment. Tax evasion activity is risky because there is a certain probability that tax evasion will be discovered and punished. As suggested by t...

The purpose of this paper is to offer a formal model of corporate income tax evasion. While individual tax evasion is essentially a portfolio selection problem, corporate income tax evasion is much more complicated. When the owner of a firm decides to evade taxes, not only does it risk being detected by the tax authorities but, more importantly, the optimal compensation scheme offered to the em...

We develop a model of tax evasion based on the Ising model. We augment the model using an appropriate enforcement mechanism that may allow policy makers to curb tax evasion. With a certain probability tax evaders are subject to an audit. If they get caught they behave honestly for a certain number of periods. Simulating the model for a range of parameter combinations, we show that tax evasion m...
