State Pension reform:
The first reform measure was the long term stabilization of the rate of contribution to the Public Pension Scheme. The aim of the government was to keep the amount of contribution to finance the state pensions under 20% of the payroll till 2020 and 30% till 2030. Therefore the future plans for pension expenditure growth was revised with few changes in the indexation formula which links pension with earnings development. State pensions were indexed to the wage growth in Germany.P(t) = {TI(t-1) / TI(t-2)} * {TP(t-2) / TP(t-1)} * P(t-1).
Where P(t) = Gross pension in the time period t,
TI = Level of the net income per worker in the time period t, related with total income,
P(t) = The net pension level within the time period t, relative to the average total pension per retiree.
But this formula had been changed in 2001. The new formula was:
P(t) = {GI(t-1)/GI(t-2)} * [1- {k(t-1)^s} – {k(t-2)^p}] / [1- {k(t-2)^s} - {k(t-2)^p}] * P(t-1).
Where GI(t) = Gross incomes per worker in the period t,
k(t)^s = subsidized private savings contribution rate in the time period t
k(t)^p = rate of contribution to the Public Pension Scheme in the time period t.
This new indexation formula moderated the pension growth.
