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...

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...

Measuring effective tax rates using tax revenue data is attractive, given that revenues collected capture the net effect of tax provisions and taxpayer behaviour that are difficult to model. Yet reliance on aggregate tax and income data requires restrictive assumptions and significantly limits...

The purpose of this paper is threefold. First, we survey the way in which the tax burden on labour has been proxied for in recent multi-country macro-economic studies. Second, we criticalyy evaluate these proxies. Finally, we examine to what extent the conclusions of some studies change if some...

In Europe, declining corporate tax rates have come along with rising tax-to-GDP ratios. This paper explores to what extent income shifting from the personal to the corporate tax base can explain these diverging developments. We exploit a panel of European data on firm births and legal form of...

We analyze the distribution and taxation of top incomes in Germany during the 1990s on the basis of individual tax returns data. We derive a measure of economic income from taxable gross income as reported in the tax returns. Thanks to complete sampling, we can deliver a very precise description...

This paper considers an optimal income tax cum higher education policy. It shows that in the presence of an optimal income tax system higher education should be taxed rather than subsidized. Furthermore, income taxes should become less progressive when an optimal higher education policy is...

This paper outlines the methodology used by the OECD in its Taxing Wages publication, compares this approach to other measures of the effective tax rate on labour and uses recent results to illustrate its use. It argues that the strength of this methodology lies in its ability to make...

This paper analyses the development of the ratio of corporate taxes to wage taxes using a simple political economy model with internationally mobile and immobile firms. Among other results, our model predicts that countries reduce their corporate tax rate, relative to the wage tax, either when...

A relatively high labor-intensity in government-run entities need not imply slack in their organization. Rather, it is a rational reaction to various forms of wage tax advantage that the public sector has over private firms. Even though an unequal tax treatment of public and private sectors...
