The paper studies the power of educational investments in relation to transfers for fostering lifetime income and for reducing income inequality in Germany. The welfare analysis is based on a model of age-dependent human capital accumulation, featuring dynamic complementarities in skill...

Departing from the implication of the basic life cycle model that substantial wealth inequality may arise simply because of differences in age, at first, we investigate the quantitative importance of age as a source of wealth differences in Germany using individual wealth data from the German...

The discussion paper is concerned with the interplay between demography and macroeconomics on one hand and macroeconomics and income inequality on the other hand. For this purpose, several estimation equations are derived by econometric methods (on the empirical basis of the 1984-2010 German...

We present new empirical evidence on the distribution of earnings, income and wealth among entrepreneurs in Germany. We document that both earnings and income are more concentrated among entrepreneurs than among workers and describe a large-scale overlapping-generations model that can replicate...
