Linking retirement age to life expectancy in a Bismarckian system – the case of Germany

In times of decreasing mortality, one way to stabilise a PAYG pension system is to interrelate the retirement age to the anticipated average lifespan. This paper investigates two approaches for Germany: one is to keep the average retirement duration constant, the other to define a constant share of the total lifespan for the retirement period. Our simulation model uses a Leslie matrix population projection, a Solow-Swan growth model and a detailed calculation of the German pension insurance budget.

The sustainability of Scottish public finances: a Generational Accounting approach

This paper analyses the long-term sustainability and intergenerational equity of the Scottish public finances by employing a generational accounting model. This represents a novel approach to analysing these issues in the case of Scotland, while having the advantage of capturing policy-relevant intergenerational aspects. We find that, under the baseline scenario, assuming that Scotland has “full fiscal autonomy”, large intertemporal and intergenerational fiscal gaps open up.
