We present four important dimensions to international tax policy from a tax-systems perspective, stressing that non-rate/base tax policies can have different cross-jurisdictional spillover effects than changes in tax rates. The dimensions are the allocation of global income among taxing...

We develop a simple structural model of value added tax (VAT) compliance, and estimate it using widely available national accounts data to learn about compliance in countries where little is currently known. International border controls improve VAT compliance, generating a correlation between...

In a real-effort laboratory experiment to manipulate evasion opportunities, we study whether the moral evaluation of tax evasion is subject to a self-serving bias. We find that tax morale is egoistically biased: Subjects with the opportunity to evade taxes judge tax evasion as less unethical as...

Recent economic literature emphasizes the importance of moral considerations to explain compliance behavior with respect to underground activities such as tax evasion. A considerable amount of research aims to identify factors that affect the intrinsic motivation to comply. However, the causal...

Estimations of the shadow economies for 120 countries, including developing, Eastern Europe and Central Asian and high income OECD countries over 1999 to 2006 are presented. The average size of the shadow economy (as a percent of "official" GDP) in 2004/05 in 76 developing countries is 35.5%, in...

In this paper the main focus lies on the development and the size of the shadow economy and of undeclared work (or shadow economy labor force) in OECD, developing and transition countries. Besides informal employment in the rural and non-rural sector also other measures of informal employment...

Sub-Saharan Africa economies introduced extensive reforms of their tax systems in the last two decades. In most of these countries taxes are now remitted through the self-assessment system that relies on quasi voluntary compliance and audit selection by risk. However, the revenues from direct...

In this paper the main focus lies on the shadow economy and on work in the shadow. The most influential factors on the shadow economy are tax policies and state regulation. The size of the shadow economy was decreasing over 1999 to 2007 from 34.0% to 31.2% for 161 countries (unweighted average)....
