Each year, the government loses hundreds of billions of dollars in tax revenue due to underreporting by individual taxpayers. According to standard deterrence theory, policymakers should be able to reduce tax evasion by increasing tax penalties, raising the audit rate, or some combination of the...

We study optimal income taxation in a framework where one's willingness to report his income truthfully is positively correlated with his type. We show that allowing low-productivity types to cheat leads to Pareto-superior outcomes as compared to deterring them, even if audits can be performed...

This paper extends the standard theoretical model of tax enforcement by allowing for the cross-matching of transactions in addition to the auditing of taxpayers. For the Value Added Tax (VAT) the matching of purchase and sales invoices is an important enforcement technique. The paper examines...

Governments increasingly use changes in tax rules to combat evasion. We develop a general approach to point-identify tax compliance along with supply and demand elasticities; identification requires data on prices and quantities before and after changes in tax enforcement and a demand or supply...

This paper proposes a method for evaluating the impact of tax reform on tax revenues and the distribution of the tax burden. The technique consists of decomposing actual revenue relative to potential revenue into components attributable to (i) changes in the tax rate structure (ii) deductions...

We propose a model that captures tax avoidance as an investment under uncertainty: searching for tax loopholes or developing legal avoidance schemes is associated with costs; the tax benefit is however uncertain. Its height depends on whether or not the tax agency agrees with the chosen...

This study investigates the contagious nature of tax avoidance by examining how narratives affect tax avoiding behavior. We adapt the idea of narrative economics indicating that individuals' actions are stimulated by stories that spread within a society. We employ two types of infection models...

There are two ways for taxpayers to avoid paying taxes: legally, through tax optimization and illegally, through tax evasion. The government reacts by altering the law, and by conducting audits, respectively. These phenomena are modeled as a population game, a strategic interaction between all...

In this paper we try to understand the phenomena whereby a large proportion of the population evades tax payments. We present a model which incorporates elements from the theory of information cascades with the standard model of tax evasion and analyze the connection between the decision of a...
