Peter A. Diamond - Böcker

Social security systems are being reviewed and changed in many countries around the world. This nontechnical book considers some of the key policy issues for design of a social security reform, as well as reviewing much of the academic literature on the positive and normative aspects of social security.In the first chapter, Diamond's examination of key policy issues of general concern includes the funding of social security, the comparison of defined benefit and defined contribution systems, notional defined contribution accounts, alternative approaches to organizing individual defined contribution accounts, and the provision of survivor benefits. Diamond turns then to the academic literature on the interactions between social security and the labor and capital markets, providing a non-technical overview of the existing literature and pointing-out gaps in current research findings. Chapter Two reviews the impact on retirement decisions of forced savings, the use of an earnings or retirement test, mandated annuitization, recognizing heterogeneity in both life expectancy and possibly in risk classification for annuity pricing, and treatment of the family, particularly the use of joint-life annuitization. Also reviewed is the impact on labor supply at younger ages, considering mandatory savings and annuitization, contrasting defined benefit and defined contribution systems, and analysing alternative approaches to redistribution within social security. The final chapter covers issues of aggregate capital accumulation and risk-sharing, with the latter including the risks in annuitization, in the returns to capital, and in aggregate earnings. Also considered are the risks in the political process.

In these two lectures, first published in 1994, Peter Diamond explores how time is modelled in theoretical analyses of individual industries and of an entire economy. In the first lecture he considers equilibrium in a single market by examining the distinction between the short run and the long run in Marshallian analysis. He proposes an explicit modelling of time in place of Marshall's use of different atemporal models for different time frames. In the second lecture he turns to models of an entire economy, and begins by considering how and why models of an entire economy should differ from models of a single industry. Both cyclical and seasonal data on the behaviour of macro-economies are examined.

Recent reports predict that, barring any changes, the Social Security program will become insolvent--no longer able to pay promised benefits in full--around the year 2030, well within the retirement years of the baby boom generation. They also predict that the trust fund will stop being a net contributor and become instead a net claimant on the federal budget in the year 2013--much earlier than previously thought. With the world population aging, the increasing number of dependent senior citizens in all countries will become a major public policy issue that will have to be addressed continually over the next fifty years.Social Security: What Role for the Future? takes a fresh look at the questions essential to understanding the future of old-age protection under Social Security. Experts in economics, actuarial science, and public policy examine such front-burner issues as the effects that variables such as mortality, births, inflation, wage levels, and pension benefits will have on the income of future retirees; the implications and effects of alternative levels of funding and financing on Social Security; and the prospects for publicly and privately financed income programs. The authors conclude with an examination of social security programs around the world and pose critical questions about the future direction of Social Security in the United States--questions that Congress and the American public will have to address in the coming years.The contributors include Robert H.
