As can be seen from the following figures, there is indeed a level increase of GDP, however this is
mostly explained by the increase in employment. Additional effects from increased capital
accumulation only arrive gradually. Over the first 15 to 20 years, the transition does not lead to
additional savings.

5. Conclusions
This paper has provided a projection on the likely macroeconomic impact of leaving the current
PAYG system in place and has analysed a number of alternative strategies of avoiding an increase
in non-wage labour costs. Special emphasis was laid on the question whether a partial move to a
funded system could be a feasible option from a budgetary perspective under the constraint that
age cohorts older than 40 must be subsidized by the general public over a transition period. At
least for the transition as outlined in this paper, the fiscal costs appear to be rather large and hardly
feasible from a budgetary perspective.
Apart from the generosity in which older worker cohorts are compensated, the crucial question is,
what are the real growth effects of such a reform and what is happening to growth of the tax base.
In this paper it is found that the macroeconomic benefits from a transition to a funded system are
limited, initially because the build up of government debt is crowding out private investment
activities. Higher savings occur in the longer term. However, in an ageing open economy it is
likely that a substantial fraction of savings will be invested abroad. The question arises whether it
will be possible to tax the returns from foreign assets.
