The chapter lays out principles for a universal system of supplemental retirement income coverage based on mandatory contribution levels, mandatory portability, limitations on early withdrawals, and annuitization. The structure outlined envisions continued participant and employer choice of both investment strategy and benefit design, with incentives built in for collective asset management.Opinions and conclusions are solely those of the author(s) and do not reflect views of the institutions supporting the research, with whom the authors are affiliated, or the Pension Research Council.
