This study analyses the adjustment of the Finnish earnings-related pension system to very low economic growth. The results show that a permanently lower growth rate of the wage bill would raise only moderately the pension contribution rates in the long term. This is because also the benefits are partially linked to wages. But if the rate of return on the pension fund investments would also go down, the contribution rates would increase significantly. External competitiveness and employment would weaken as well as the position of future generations. The study presents a pension reform that stabilizes the contribution rate by raising the retirement age and cutting pensions. These kind of specific reforms are not, however, optimal due to demographic and economic uncertainty. A better solution would be automatic adjustment rules that are designed to provide accepted redistribution of income between various generations.
