This paper explores the introduction of collective risk-reallocation elements in de fined contribution pension contracts. We consider status-contingent, age-contingent and asset-contingent arrangements to reallocate risk among participants. Eliminating asset market risk for the retired raises their welfare, while it lowers welfare of the workers, despite the fact that they bene fit later from the same arrangement. Overall welfare falls. The welfare effects are largest when personal and pension portfolios are optimally chosen. Allowing for intragenerational heterogeneity, the highest-skilled retirees bene fit most, while the highest-skilled workers lose most. Our main results are qualitatively robust to a number of model variations and extensions.
