This article provides an overview of the Retirement Research Consortium (RRC) from the Social Security Administration's perspective, including a brief history of the development of the RRC, a discussion of the aims of the RRC, and some thoughts on its future. The mission of the RRC is to plan and conduct a broad research program to develop Social Security and retirement policy information to assist policymakers, the public, and the media in understanding the issues. The RRC has been a remarkably successful extramural research venture that has advanced the knowledge base on Social Security and retirement issues, trained new scholars to become the next generation of Social Security and retirement policy experts, and provided objective, research-based input to the policymaking process.

This article reviews the research contributions of the Center for Retirement Research at Boston College over its 10-year history and their implications for Social Security and retirement income policy in three major areas: (1) Social Security's long-term financing shortfall, (2) the adequacy of retirement incomes, and (3) labor force participation at older ages as a means to improve retirement income security. The center has received substantial funding support from the Social Security Administration (SSA) in each area and has also successfully leveraged SSA's investment by attracting funding from other sources.

The Office of Retirement and Disability Policy at the Social Security Administration created the Retirement Research Consortium in 1998 to encourage research on topics related to Social Security and the well-being of older Americans, and to foster communication between the academic and policy communities. The Michigan Retirement Research Center (MRRC) has participated in the Consortium since its inception. This article surveys a selection of the MRRC's output over its first 10 years and highlights several themes in the Center's ongoing research.

Since September 2003, the Retirement Research Center at the National Bureau of Economic Research has conducted a coordinated series of investigations on Social Security in a changing environment and the potential routes to sustainable solvency. The Center supports extensive collaborative research over a multiyear horizon to achieve a more fully integrated understanding of Social Security's challenges and the changing environment in which it operates. This article is an overview of the studies completed since the Center's inception.
