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...

In this paper we study the distributional impact of a change from the existing pay-as-you-go Social Security system to one that combines both pay-as-you-go and investment-based elements. Critics of investment-based plans have been concerned that such plans might reduce the retirement income of...

This paper examines the risk aspects of an investment-based defined contribution Social Security plan. We focus on the risk after the plan is fully phased in. Individuals deposit a fraction of wages to a Personal Retirement Account (PRA), invest these funds in a 60:40 equity-debt mix, and in a...

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...

This paper analyzes the transition from the existing pay-as-you-go Social Security program to a system of funded Mandatory" Individual Retirement Accounts (MIRAs). Because of the high return on real capital relative to the very low return in a mature pay-as-you-go program, the benefits that can...

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...

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...

In this paper we revisit the debate over the role of the banking panics in 1930-33 in precipitating the Great Contraction. The issue hinges over whether the panics were illiquidity shocks and hence in support of Friedman and Schwartz (1963) greatly exacerbated the recession which had begun in...

This paper examines the economic environments in which past U.S. stock market booms occurred as a first step toward understanding how asset price booms come about and whether monetary policy should be used to defuse booms. We identify several episodes of sustained rapid rise in equity prices in...

The analysis in this paper was motivated by the apparent puzzle that, despite substantial uncertainty about future inflation rates, private pensions are almost universally unindexed. Moreover, although a variable annuity invested in short-term money market instruments provides a good inflation...
