This study provides new evidence on top income shares in Germany from industrialization to the present. Income concentration was high in the nineteenth century, dropped sharply after WWI and during the hyperinflation years of the 1920s, then increased rapidly throughout the Nazi period beginning in the 1930s. Following the end of WWII, German top income shares returned to 1920s levels. The German pattern stands in contrast to developments in France, the United Kingdom, and the United States, where WWII brought a sizeable and lasting reduction in top income shares. Since the turn of the millennium, income concentration in Germany has been on the rise and is today among the highest in Europe. The capital share is consistently positively associated with income concentration, whereas growth, technological change, trade, unions, and top tax rates are positively associated in some periods and negative in others.

We compare the evolution of earnings instability in Germany and the United Kingdom, two countries which stand for different types of welfare states. Deploying data from the German Socio-Economic Panel (SOEP) and the British Household Panel Survey (BHPS), we estimate permanent and transitory variances of male income over the period 1984-2009 and 1991-2006, respectively. Studies in this literature generally use individual labor earnings. To uncover the role of welfare state and households in smoothening earnings shocks, we compute different income concepts ranging from gross earnings to net equivalent household income. We find evidence that the overall inequality of earnings in Germany and the United Kingdom has been rising throughout the period due to both higher permanent earnings inequality and higher earnings volatility. However, taking institutions of the welfare state and risk-sharing households into account, we find that the volatility of net household income has remained fairly stable. Furthermore, redistribution and risk insurance provided by the welfare state is more pronounced in Germany than in the United Kingdom.

Abstract. Welfare states redistribute both between individuals reducing annual inequality and over the life-cycle insuring against income risks. But studies measuring redistribution often focus only on a one-year period. Using German SOEP data from 1984 to 2009, long-term inequality over a 20-year period is computed and then decomposed into an inter-and intra-individual component. Results show that annual inequality is higher than long-term inequality, but redistribution is also larger annually. In the long-term, the German welfare state clearly gives priority to insurance over redistribution. This gets even more pronounced at later stages of the life-cycle through the payment of social security pensions.
