Social Security Policy in a Changing Environment analyzes the changing economic and demographic environment in which social insurance programs that benefit elderly households will operate. It also explores how these ongoing trends will affect future beneficiaries, under both the current social security program and potential reform options. In this volume, an esteemed group of economists probes the challenge posed to Social Security by an aging population. The researchers examine trends in private sector retirement saving and health care costs, as well as the uncertain nature of future demographic, economic, and social trends—including marriage and divorce rates and female participation in the labor force. Recognizing the ambiguity of the environment in which the Social Security system must operate and evolve, this landmark book explores factors that policymakers must consider in designing policies that are resilient enough to survive in an economically and demographically uncertain society.

The United States social security system is the nation's largest social insurance program. As such, it has a far-reaching impact throughout the economy, influencing not only old-age economic security but also many behaviors, including corporate employment policy, retirement patterns, and personal saving. In the past, the system's universal coverage and generous benefits ensured popular support to a degree enjoyed by no other form of "big government" social spending. Yet over two-thirds of all Americans today believe that the social security system will face bankruptcy by the time they retire. The question of social security reform—how to reform the system or whether the system needs reform at all—is the subject of heated debate at all levels of government, in the media, and among workers, pensioners, and employers. Prospects for Social Security Reform informs the debate by exploring why the system is at a crossroads today and what to do about it. Contributors detail the size and nature of the problem, explain views of key "stakeholders" regarding reform options, and report new evidence on how reform might affect the economy. Research findings and public opinion polls are analyzed, as are lessons from other countries experimenting with new ways to deliver old-age benefit promises. No other volume includes as diverse and expert a set of perspectives on reform and privatization as those gathered here from economists, actuaries, employers, investment managers, and representatives of organized labor. Among its chapters is the path-breaking study "Social Security Money's Worth," the 1999 winner of the TIAA-CREF's Paul A. Samuelson Award for Outstanding Scholarly Writing on Lifelong Financial Security.

This volume represents the most important work to date on one of the pressing policy issues of the moment: the privatization of social security. Although social security is facing enormous fiscal pressure in the face of an aging population, there has been relatively little published on the fundamentals of essential reform through privatization. Privatizing Social Security fills this void by studying the methods and problems involved in shifting from the current system to one based on mandatory saving in individual accounts. "Timely and important. . . . [Privatizing Social Security] presents a forceful case for a radical shift from the existing unfunded, pay-as-you-go single national program to a mandatory funded program with individual savings accounts. . . . An extensive analysis of how a privatized plan would work in the United States is supplemented with the experiences of five other countries that have privatized plans." —Library Journal "[A] high-powered collection of essays by top experts in the field."—Timothy Taylor, Public Interest

Social security is the largest and perhaps the most popular program run by the federal government. Given the projected increase in both individual life expectancy and sheer number of retirees, however, the current system faces an eventual overload. Alternative proposals have emerged, ranging from reductions in future benefits to a rise in taxrevenue to various forms of investment-based personal retirement accounts. As this volume suggests, the distributional consequences of these proposals are substantially different and may disproportionately affect those groups who depend on social security to avoid poverty in old age. Together, these studies persuasively show that appropriately designed investment-based social security reforms can effectively reduce the long-term burden of an aging society on future taxpayers, increase the expected future income of retirees, and mitigate poverty rates among the elderly.

Chapters include: "Income distribution and welfare programs", "State and local government expenditures" and "Health economics and private health insurance".

Everyone agrees on the need to reform Medicare but not on how to do it. Some argue the program is too comprehensive, others that it is not comprehensive enough. Some suggest it pays too much for health care, others, too little. Meanwhile, the financial stakes continue to mount. Medicare spending exceeded $400 billion in 2007, making it more expensive than the entire health systems of most other nations, as well as the largest national public program other than Social Security and national defense. In R eforming Medicare, Henry J. Aaron and Jeanne M. Lambrew deftly guide readers through this complex debate. They identify and analyze the three leading approaches to reform. Updated social insurance would retain the current system while rationalizing coverage and reducing bureaucracy. Premium support would replace the current system with a capped, per-person payment that beneficiaries could use to buy health insurance. Consumer-directed Medicare would have beneficiaries pay for care up to a high deductible from government- supported savings accounts and offer premium-support coverage above the deductible. In addition to rating each option on its ability to promote access to health care, improve the quality of care, and control costs, the authors evaluate each reform's political strengths and weaknesses. Given the heat generated by the Medicare debate, it is unlikely that any single approach will be implemented in full. Consequently, Aaron and Lambrew describe incremental strategies that blend elements of each plan. Their analysis provides essential insight into the types of hybrid policies that Congress will consider in coming years.
