Marginal income tax rates in advanced industrial countries have fallen
dramatically since the mid-1980s, but level and progressivity of income
taxation continue to differ strongly across countries. This study offers a
new perspective on both observations. It blends theoretical inquiry with
focused quantitative analysis and in-depth investigation of seven countries:
Germany, Australia and New Zealand as well as Denmark, Finland, Norway and
Sweden. The study highlights the equity-efficiency tradeoffs that structure
the politics of income taxation and analyses how income taxes are embedded
in broader tax systems. It explains the limited but enduring importance of
political parties and democratic institutions. Finally, the study paints a
nuanced picture of the role of globalisation and thus also sheds lights on
the pros and cons of tax coordination at the European and international
levels.
