Together, pensions, social security and health insurance account for half of the wealth held by all households in the Health and Retirement Study (HRS), for 60 percent of total wealth of HRS households who are in the 45th to 55th wealth percentiles, and even for 48 percent of wealth for those in...

We argue that strategic interactions between firms in an oligopoly can explain the puzzling lack of high-powered incentives in executive compensation contracts written by shareholders whose objective is to maximize the value of their shares. We derive the optimal compensation contracts for...

There has been rapid growth in `self-directed' pension programs such as the 401(k) plan. Because such plans are voluntary, there is concern that many workers neglecting to contribute will reach retirement with inadequate pension saving. First, we show that people who are eligible for 401(k)s, do...

We estimate the fraction of the wealth of a sample of PSID respondents that is held because some households face greater income uncertainty than others. We first derive an equation characterizing the theoretical relationship between wealth and uncertainty in a buffer-stock model of saving. Next,...

This paper uses the Panel Study of Income Dynamics to provide some of the first direct evidence that wealth is systematically higher for consumers with greater income uncertainty. However, the apparent pattern of precautionary saving is not consistent with a standard parameterization of the life...

We develop a contracting model between shareholders and managers in which managers diversify their firms for two reasons: to reduce idiosyncratic risk and to capture private benefits. We test the comparative static predictions of our model. In contrast to previous work, we find that...

The market value of corporate stock in the United States increased by nearly one trillion dollars between December 1994 and July 1995. This paper explores the distribution of the stock ownership, and hence the gains from the stock price rise, and what the rise in stock prices implies for...

Do firms systematically over- or underinvest as a result of agency problems? We develop a contracting model between shareholders and managers in which managers have private benefits or private costs of investment. Managers overinvest when they have private benefits and underinvest when they have...

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...
