Abstract

We evaluate the performance of and level of intergenerational cross subsidy in single-employer and multi-employer collective defined contribution (CDC) schemes which have been designed to be compatible with UK legislation. The single-employer scheme captures the essential features of the Royal Mail CDC scheme, which is currently the only UK CDC scheme. We find that the schemes can be successful in smoothing pension outcomes while outperforming a DC + annuity scheme, but that this outperformance is not guaranteed in a single-employer scheme. There are significant intergenerational cross-subsidies in the single-employer scheme. These qualitatively mirror the cross-subsidies seen in existing defined benefit schemes, but we find the magnitude of the cross-subsidies is much larger in single employer CDC schemes. The multi-employer scheme is intended to minimize such cross-subsidies, but we find that such subsidies still arise due to the approximate pricing methodology implicit in the scheme design. These cross-subsidies tend to cancel out over time, but in any given year they can be large, implying that it is important to use a rigorous pricing methodology when valuing collective pension investments.
