This document summarizes a report on shifting public pension plans from defined benefit to defined contribution models. It discusses how the private sector led the shift to defined contribution plans in the 1970s-80s due to changes in tax law and accounting standards. It then examines how the federal government implemented a similar reform for federal workers in the 1980s through a new defined contribution plan paired with a reduced defined benefit plan. The document uses these cases to argue public sector employers can achieve fiscal sustainability by implementing a similar pension reform approach.
