This should be done in a way that preserves the real value of pensions, while in addition passing on part of the productivity gains achieved by the current working generation. Preserving the purchasing power of pensions would be achieved by indexing minimum pension increases at least to the inflation rate for low-income households, which has been slightly above general consumer price inflation in recent years. Beyond this inflation-adjustment, the political question is how much of the productivity gains achieved by the current working generation should be passed on to pensioners, or in other words, at which point between inflation-adjustment and average wage increases the pension indexing factor should be placed.
