This paper presents new evidence on how corporate payout policy responds to the differential between the tax burden on dividend income and that on accruing capital gains. It describes the construction of weighted average marginal tax rate series for the period since 1929, and it suggests that the enactment of the Job Growth of Taxpayer Relief Reconciliation Act of 2003 should raise the after-tax value of dividends relative to capital gains by more than five percentage points. The impact of this change on payout depends on the elasticity of dividend payments with respect to the after-tax value of dividend income relative to capital gains. Time series estimates suggest an elasticity of more than three, and imply that the recent tax reform could ultimately increase dividends by almost twenty percent.

Elderly individuals exhibit wide disparities in their sources of income. For those in the bottom half of the income distribution, Social Security is the most important source of support; program changes would directly affect their well-being. Income from private pensions, assets, and earnings are relatively more important for higher-income elderly individuals, who have more diverse income sources. The trend from private sector defined benefit to defined contribution pension plans has shifted responsibility for retirement security to individuals. A significant subset of the population is unlikely to be able to sustain their standard of living in retirement without higher pre-retirement saving.

The sharp decline in the stock prices of several firms at which employees held a large fraction of their 401(k) plan assets in company stock, including Enron, Global Crossing, Lucent, and Polaroid, has sparked a public-policy debate about investment options in 401(k) plans. At many large firms, particularly those with retirement saving plans that combine elements of an Employee Stock Ownership Plan (ESOP) with a traditional 401(k), a substantial fraction of defined-contribution retirement-plan assets are held in company stock. Such undiversified holdings are a source of concern because they raise the volatility of the retirement wealth for employees and expose some workers to the prospect of very small retirement values. Holding an undiversified position in employer stock may be particularly costly because of the potential correlation between company stock returns and the value of the worker’s human capital, which may depend on the company’s prospects. This paper reviews the extent of undiversified company-stock investments in 401(k) plans, evaluates the cost of such investments from an employee’s perspective, and discusses a range of policy actions that could address the excessive concentration of retirement plan assets.
