We develop and estimate a life-cycle consumption savings model in which observed genetic variation is allowed to affect wealth accumulation through several distinct channels. We focus on genetic markers that predict educational attainment, aggregated into a predictive index called a polygenic...

Against a background of projections of sharply increasing elderly dependency rates, workers in the major industrial economies are apprehensive that their social security benefit entitlements will be cut before or after they retire, leaving them with inadequate retirement income. This paper looks...

We evaluate several actual and hypothetical sustainable PAYGO pension structures, including: (1) versions of the US Social Security system with annual adjustments of taxes or benefits to maintain fiscal balance; (2) Sweden's Notional Defined Contribution system and several variants developed to...

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...

Projected demographic changes in industrialized and developing countries vary in extent and timing but will reduce the share of the population in working age everywhere. Conventional wisdom suggests that this will increase capital intensity with falling rates of return to capital and increasing...

Social Security trust fund portfolio diversification to include some equities reduces the equity premium by raising the safe real interest rate. This requires changes in taxes. Under the hypothesis of constant marginal returns to risky investments, trust fund diversification lowers the price of...

An economic theory of public and private pensions is developed, and the implications of the theory are compared with some empirical evidence, of both the econometric and casual varieties. Among the questions addressed are: why are there private pensions? why have they grown so rapidly in recent...

In contrast to some recent studies, the findings suggest the flow of wives into the labor force in the last few decades has probably reduced the amount of husbands' work. The model also provides plausible responses to various policies. For example, we find that any effort to promote...

Earlier claims that pensions serve as severance pay are corroborated by a new data set drawn from the 1980 Banker's Trust corporate pension plan study. A model is developed that shows how pension values which vary with the age of retirement make both workers and firms better off by moving the...

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...
