Beetsma, R. and Bucciol, A. (2015). Risk reallocation in defined-contribution funded pension systems Macroeconomic Dynamics, 19(1):22--57.

This paper explores the introduction of collective risk-reallocation elements into defined-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, whereas it lowers the welfare of the workers, despite the fact that they benefit 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 benefit most, whereas the highest-skilled workers lose most. Our main results are qualitatively robust to a number of model variations and extensions.
