China has legislated a mixed social security pension system with a defined benefit pay-as-you-go portion and an investment-based defined contribution portion. This paper analyses the economics of these two types of systems in the Chinese context and calculates the advantage to China of using an...

The ageing of the population presents a major fiscal challenge for the countries of Europe. The combination of increased longevity and a reduced birth rate will directly reduce the growth rates of the European economies by slowing the growth of the capital stock and by weakening the productivity...

This lecture discusses the economic losses that result from an unfunded social security retirement system and the potential gain from shifting to a funded system. The social security payroll tax distorts labor supply and the form in which compensation is paid. Although each individual's benefits...

In an earlier paper we analyzed a method of combining traditional tax financed pay-as-you-go Social Security benefits with annuities financed by Personal Retirement Accounts. We showed that such a combination could maintain the level of retirement income projected in current Social Security law...

This paper presents several alternative Social Security reform options in which the projected level of benefits for every future cohort of retirees is as high or higher than the benefits projected in current law. These future benefits can be achieved without any increase in the payroll tax or in...

This paper presents a detailed analysis of the economics of prefunding benefits for the aged, focusing on Social Security but indicating some of the analogous magnitudes for prefunding Medicare Benefits. We use detailed Census and Social Security information to model the transition to a fully...

This paper reexamines the results of my 1974 paper on Social Security and saving with the help of an additional twenty-one years of data. The estimates presented here reconfirm that each dollar of Social Security wealth (SSW) reduces private saving by between two and three cents. The parameter...

In this paper we study the transition from a pay-as-you-go system of Social Security pensions to an investment-based system in an economy in which portfolio returns and capital profitability are both uncertain. The paper extends earlier studies by Feldstein and Samwick that modeled the...

A program of Personal Retirement Accounts (PRAs) funded by deposits equal to 2.3 percent of earnings (up to the Social Security maximum) would permit retirees to receive more income in retirement than with the current Social Security program while at the same time making it unnecessary to...

This paper discusses a possible solution to the double problem that faces European governments in dealing with the future of Social Security pensions. Like other governments around the world, they must deal with the rising cost of pensions that will result from the increasing life expectancy of...
