The German statutory pension scheme: Balance sheet, cross-sectional internal rates of return and implicit tax rates

摘要

We present a framework for accounting of the German statutory pension scheme and estimate a balance sheet for the years 2005 until 2012. Extending and applying the methodology proposed by Settergren and Mikula (2005), we estimate the cross-sectional internal rates of return of the German pension scheme over this period. We are able to show that the cross-sectional internal rate of return is mainly financed by increasing contributions and by changing the liabilities not backed by assets. Additionally, our results reveal that from an expenditure perspective, the major part of the internal rate of return is resulting from changing longevity rather than indexation of pension entitlements. Finally, we prove that from a cross-sectional perspective the implicit tax of a pension scheme can mainly be interpreted as an u201cimplicit wealth taxu201d on pension wealth and subsequently present empirical estimates for these cross-sectional implicit tax rates.
