This paper begins by contrasting the caricatures "homo and femina economicus" with "homo and femina realitus". Against this backdrop, the paper considers three "apparently falsified" empirical predictions of the standard expected utility model of individual decision-making concerning...

This article incorporates tax evasion into an optimum taxation framework with individuals differing in earning abilities and initial wealth. We find that despite the possibility of its evasion a tax on initial wealth should supplement the optimal nonlinear income tax, given a positive...

We study experimentally how taxpayers choose between two tax regimes to fund a public good. The first-best tax regime imposes a general, distortion-free income tax. However, this tax cannot be enforced. The second-best alternative supplements the income tax by a specific commodity tax. This tax...

This paper studies the Marginal Cost of Funds (MCF) in the existence of tax evasion. When tax evasion is incorporated as a behavioral response to tax rate change, the MCF can be different than the previously estimated ones in the literature. We develop a general equilibrium model of tax evasion,...

Relative consumption effects or status concerns that feature jealousy (in the sense of Dupor and Liu, AER 2003) boost consumption expenditure. If consumption is financed by labour income, such status considerations increase labour supply and, hence, the tax base. A higher taxable income, in...

Tax evasion is modeled as a risky activity and integrated into a standard problem of optimal tax design. It is shown that there is a trade off between reducing tax evasion and reducing tax distortion. Thus it is efficient to supplement a broad-based wage tax by a tax on specific consumption if...

The paper discusses the applicability of optimal taxation theory to source-based capital incomes when significant tax evasion is observed. Without tax evasion a modified Ramsey Rule may reduce distortions brought by international capital mobility, leading to levying differentiated tax rates in...

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...
