We exploit an exhaustive administrative dataset that includes the individual tax returns of all households in the top percentile of the income distribution in Germany to pin down the effective income taxation of households with very high incomes. Taking tax base erosion into account, we find...

The idea of higher wealth taxes to finance the mounting public debt in the wake of the financial crises is gaining ground in several OECD countries. We evaluate the revenue and distributional effects of a one-time capital levy on personal net wealth that is currently on the German political...

A large literature has documented top income share series based on income tax statistics using the common methodology established by Piketty (2001, 2003). The disappearance of capital income from the income tax base in many countries poses a major challenge to the comparability of these series...

Welfare states redistribute both between individuals (inter-individual redistribution) reducing annual, cross-sectional inequality and over the lifecycle of an individual (intra-individual redistribution) insuring individuals against income risks in the long-term. But studies measuring...

This paper provides formulas for optimal top marginal tax rates when couples are taxed according to income splitting between spouses, consumption is taxed, and the skill distribution is unbounded. Optimal top marginal income tax rates are computed for Germany using a dataset that includes the...

Deploying data from the German Socio-Economic Panel (GSOEP) we analyze the variability of individual earnings and equivalent household income. Permanent and transitory variances of male income over the period 1984-2008 are estimated for Old German Laender in order to determine their importance...

This paper points to flaws in Gini decompositions by income sources and population subgroups and to common pitfalls in the interpretation of decomposition results, focusing on methods within the framework of Rao (1969). We argue that within this framework Gini elasticities may provide the only...

Mobility of top incomes matters for both the openness of the income elite and the share of total income that this group receives. It is thus an important complement information to the growing snapshot literature on top income concentration. I use microlevel panel data of German income tax files...

We analyze the distributive justice of the combined burden of income taxes, social security taxes and public transfers on employee households in the United States on the federal level and in six member states. To investigate whether the treatment of families by the aggregate tax and transfer...

In view of rising concerns over increasing inequality in the European Union since the financial crisis, this study provides an inequality decomposition of the overall European income distribution by country. The EU Statistics on Income and Living Conditions are our empirical basis. Inequality...
