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...

Recent reforms that aim at reducing the upcoming burdens of population ageing might seriously harm low income individuals. An increase in old-age poverty and disability will be the result. Under this prospect, the present paper quantitatively characterizes the optimal progressivity of unfunded...

We ask whether a PAYG-financed social security system is welfare improving in an economy with idiosyncratic and aggregate risk. We argue that interactions between the two risks are important for this question. One is a direct interaction in the form of a countercyclical variance of idiosyncratic...

Just a few months after the federal elections in Germany, the so called pension package entered into force. It mainly contains three measures: higher pensions for mothers with children born before 1992 ("mother pension"), a reduced retirement age for persons who contributed to the pension system...

In 2007 Germany has introduced a pension reform which increases the normal retirement age from currently age 65 to 67. The present study aims to quantify the macroeconomic, welfare and efficiency consequences of this reform by means of a computable general equilibrium model with overlapping...
