Abstract: Germany, like many other countries, has undergone a series of pension reforms since the 1980s which generally decreased benefit generosity and increased the retirement age due to demographic pressures. This paper investigates whether these reforms have increased income and wealth inequality among retirees. In order to answer this question, we employed counterfactual simulations in which we predict how the income and social security wealth distributions would have developed if these reforms had not taken place, compared to the actual development of the income and social security wealth distributions. Our analysis reveals that the pension reforms has led to an increase in inequality in terms of social security wealth between the 1990s and 2000s and decreased inequality thereafter. The decrease in inequality is mainly driven by social assistance as it represents a lower bound for benefit size and thus mitigates the effect of benefit-reducing reforms for lower income groups. We further divided the total effect of the pension reforms into two components. The first component is the mechanical effect, which keeps retirement probabilities constant and only considers changes in benefit calculation. The second component is the behavioral effect, which describes how SSW differs because of altered retirement probabilities. Our findings indicate that in the German context the behavioral effect is statistically significant but economically small.
