With the transition to DC accounts the redistribution due to uniformity pricing’ that was implicit in the DB contract will be abolished and solvency requirements adjusted. This paper analyses how the transformation affects different generations. Special attention will be given to the modelling of the collective add-on to the contract (in the form of a solidarity reserve) that aims to strengthen risk sharing among generations. The effects of the reform will be analyzed for three outcome measures: pension results (in terms of replacement rates), market valuation of pensions net of contributions (‘net benefit’), and welfare measured in certainty equivalent consumption (measured through equivalent replacement rates). How the reform impacts different generations proves to be very sensitive to the measure used. There is little consensus neither in economic theory—nor in politics—on what is the best measure. It is sensitive to perspectives, and different traditions in economics focus on different measures. This paper will discuss how economic analysis can still be useful for actual policy making in such a sensitive domain as a pension reform. Finally, by investigating alternative parametrizations of the contract the paper aims to provide insight into the robustness of the results under alternative measures, and on how the new contract could be further improved.
