Description: The article first tries to determine a consensus view of what social security should accomplish and then tries to measure how well the current level of benefits succeeds in meeting these goals. Assessing benefit adequacy is an essential element in putting the overall program on a sound financing footing.

Description: The traditional defined-benefit (DB) plan is a type of plan structured to provide the greatest degree of retirement income security, designed to pay out a guaranteed retirement income for the life of the retiree (and, when applicable, a beneficiary). However, over the last several decades, the number of private-sector employees covered under these traditional plans has decreased dramatically and been replaced by defined contribution (DC) plans. In contrast, public-sector retirement plans, which are exempt from ERISA, have seen a much smaller decline in DB plans. There are many differences in the private and public sector that likely contributed to this phenomenon, but ERISA and the many amendments to it has been a major factor.

Description: Collective Defined Contribution Plans offer an option in plan design that lies somewhere between defined benefit and defined contribution plans. This is achieved by fixing the contributions to the plan, but allowing benefits to fluctuate based on experience. This article provides a basic summary of how they can be structured. There are limitations to their use in the US, but are gaining in popularity elsewhere around the globe.
