In statutory pension insurance, the contributions collected in a year are paid out to the current pensioners according to the pay-as-you-go system. The pensions of the parents’ generation are thus paid for by the generation of their children.
The current system can also be interpreted as insurance against childlessness. Every additional child increases the pensions of the parents’ generation at the existing rates of contribution. However, one’s own parents only benefit to a small extent from the contribution payments made by their children. The benefit to society of a child thus clearly exceeds the benefits that the parents receive. Measured in terms of social benefits, parents who only take their own benefits into consideration decide to have too small a number of children. To correct this flaw in the state pension system, Hans-Werner Sinn recommends topping up the state pension with a child allowance pension for parents, which would naturally be paid out in addition to their existing pension claims.
