The Sustainability of the German Statutory Pension System: Demographic Change, Financing and Intergenerational Fairness

Germany’s statutory pension insurance is principally organised around employees, while self-employed people, civil servants, members of parliament and other groups are covered by different arrangements or are not mandatorily covered at all. This article examines whether a gradual transition towards an earners’ insurance could broaden the financing base and dampen contribution-rate pressure without creating an unsustainable accumulation of future pension liabilities. It develops a transparent partial model that separates four effects: the mechanical expansion of contributory earnings, the acquisition of additional pension entitlements, compliance and administrative costs, and transitional fiscal obligations. Using illustrative baseline assumptions documented in the author’s reform concept, including approximately 38 million current contributors and a potential expansion of approximately 3 million contributors, the analysis compares a status quo, a partial-inclusion and a full new-entrant scenario. The results show that broader coverage can generate a meaningful short- and medium-term cash-flow effect. However, the net long-term effect is smaller than the mechanical revenue gain because newly insured persons acquire pension rights and because civil-service and professional-system transitions may require additional public financing. The article concludes that an earners’ insurance is a plausible component of pension reform, especially when introduced for new entrants and accompanied by transparent cohort accounting, but it cannot by itself remove demographic pressure or guarantee a lower contribution rate.
