Terms of use: Documents in EconStor may Mobility of Top Incomes in GermanyKatharina Jenderny † * May 2013Abstract 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 that is highly representative for top income households. Top income mobility is assessed in four dimensions: (i) its stability over time, (ii) the degree of mobility between top income fractiles, (iii) the degree of mobility between equally sized groups and mobility in ranks, both of which do not depend on fractile sizes, and (iv) mobility's impact on distributional results.Mobility in terms of annual fractile changes is high between the richest top income fractiles, which is primarily due to tiny fractile sizes. When the fractiles' sizes are controlled for, top income recipients' mobility is lower than that of lower income tax units.

This paper analyzes the effect of the introduction of a flat tax schedule on capital income on the progressivity of the German personal income tax, with a particular focus on top income groups.The reform-induced change in net incomes is proposed as a measure for progressivity changes at the top. Changes in vertical and on horizontal equity are analyzed and broken down by reform component. The analysis is based on a micro-level panel dataset of income tax returns between 2001 and 2006 that is particularly representative for the top of the income distribution. The panel structure is used to construct a permanent reform effect that is less prone to annual volatility in income composition. The reform is found to be regressive. It is shown that the reform included substantial loopholes. Within the top of the distribution, the gain in net incomes is spread widely, but is not negative under plausible assumptions on reporting adjustments.
