Estimations of the size and development of the shadow economy for 145 countries, including developing, transition and highly developed OECD economies over the period 1999 to 2003 are presented. The average size of the shadow economy (as a percent of officialʺ GDP) in 2002/03 in 96 developing...

This paper examines the impacts of a wide range of tax provisions on the incentive to invest in human capital, and shows how these effects can be quantified using effective tax rates, or ETRs. For individuals with median earnings, ETRs on the human capital formed in first-degree university study...

Forward looking measures like the well-known effective marginal tax rate developed by King and Fullerton (1984) are often criticized for not taking into account the complexity of the tax law. This paper derives a method of evaluating this kind of measure and of quantifying the bias resulting...

According to economists, severe legal sanctions deter violations of the law. According to legal scholars, people may obey law backed by mild sancions because of norm-activation. We experimentally investigate the effects of mild and severe legal sanctions in the provision of public goods. The...

We examine a setting in which property rights are initially ambiguously defined. Whether the parties go to court to remove the ambiguity or bargain and settle privately, they incur enforcement costs. When the parties bargain, a version of the Coase theorem holds. Despite the additional costs of...

Tax compliance has been studied in economics by analysing the individual decision of a representative person between paying and evading taxes. A neglected aspect of a tax compliance is the interaction of taxpayers and tax authorities. The relationship between the two actors can be understood as...

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...

The standard model of tax evasion based on the subjective expected utility maximization does not perform particularly well in econometric analyses: it predicts too little evasion and produces unsatisfactory econometric parameter estimates. The model is extended by looking at how the tax...

In economies with competitive labour markets social policies harm employment and output. In Europe, in particular, non-competitive labour markets with trade unions, efficiency wages and/or costly search and mismatch seem more realistic. Social policies such as progressive taxation or...

A key figure which can be applied to measuring inter-generational imbalances involved in existing public pension schemes is given by the "implicit tax" that is levied on each generation's life-time income through participation in these systems. The implicit tax arises from the fact that, quite...
