Costs of Changing Plan Design

So far there has been no large scale shift in plan design for the primary pension benefits of state and local government employees; although it has been proposed and studied in a number of states as well as at a macro level.

A 2008 study by the National Institute on Retirement Security, updated in 2014, found that defined benefit plans are 48% more cost efficient than defined contribution plans when measured at any level of retirement benefit. This is largely because defined benefit plans pool longevity risks or large groups of people as opposed to defined contribution plans which are designed to provide benefits to one individual. Defined benefit plans also enjoy greater returns on investment due to professional management and the advantages of economies of scale.

There are advantages and disadvantages to defined benefit and defined contribution plan designs, both to the individual retiree and the organization administering the plan.

What's New at NASRA: Updated Cost of Living Issue Brief

Cost-of-Living Adjustments (COLAs) play a significant role in public pensions. They help retirees keep up with rising prices, but they also add costs to pension plans. Policymakers and plan sponsors are tasked with balancing three things: benefits adequacy, plan sustainability, and affordability for members and plan sponsors.

The recent increase in inflation caused many policymakers and, in some cases pension trustees, to review how benefits are designed and paid for, including the way COLAs are granted and funded. NASRA’s recently updated issue brief on the lates trends in COLAs is available in the NASRA Research Center.
