Book excerpt: The private pension system, together with Social Security, has provided millions of Americans with income security in retirement. But over the past thirty years, pension coverage has stagnated, leaving behind some vulnerable groups. Defined contribution plans have exposed workers to greater investment risk, while cash balance and other hybrid plans may have adverse effects on older workers caught in the transition. Pension regulations, infamous for their complexity, can be bewildering to policy analysts and policymakers. Private Pensions and Public Policies sheds timely and much-needed light on specific issues within the broader context and framework of pension reform. Contributors focus on topics that must be addressed in any reform effort, including the effects of the shift in emphasis toward defined contribution plans (after the 1974 Employee Retirement Income and Security Act) and hybrid plans (from the 1990s); regulatory issues such as nondiscrimination rules and contribution limits; how to increase the information available to participants and improve financial education; how participants in defined contribution plans make choices on questions such as asset allocation, back-loaded versus front-loaded saving, and annuities versus lump sum distributions; and the interaction of the private pension system with Social Security.
