Martin Stuart ("Marty") Feldstein, currently George F. Baker Professor of Economics at Harvard University and President Emeritus of the National Bureau of Economic Research, Inc. (NBER), is a renowned American economist who has made important contributions to public finance, macroeconomics,...

A funded social security retirement program would imply a larger capital stock and a higher level of real income than an unfunded program that provides the same level of benefits. The transition from an unfunded program to a funded program that does not reduce the benefits of existing retirees...

This paper examines the risk aspects of a fully phased-in investment-based defined contribution Social Security plan. Individuals save a fraction of wages in a Personal Retirement Account (PRA) invested in a 60:40 equity-debt mix and receive a similarly invested variable annuity from age 67. The...

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 provides a relatively nontechnical discussion of the effects of shifting from a pay-as-you-go system of Social Security pensions to a fully funded plan based on individual accounts. The analysis discusses the rationale for such a shift and deals with five common problems: (1) the...

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...
