Investor decision making has always been affected by two factors: risk and returns. Considering risk, the investor expects an acceptable return on the investment decision horizon. Accordingly, defining goals and constraints for each investor can have unique prioritization. This paper develops several approaches to multi criteria portfolio optimization. The maximization of stock returns, the pow...

CONTEXT The proportion of health maintenance organization (HMO) members enrolled in investor-owned plans has increased sharply, yet little is known about the quality of these plans compared with not-for-profit HMOs.

We solve a portfolio selection problem of an investor with a deterministic savings plan who aims to have a target wealth value at retirement. The investor is an expected power utility-maximizer. The target wealth value is the maximum wealth that the investor can have at retirement. By constraining the investor to have no more than the target wealth at retirement, we find that the lower quantile...

Quality problems have long plagued the nursing home industry. While two-thirds of U.S. nursing homes are investor-owned, few studies have examined the impact of investor-ownership on the quality of care. The authors analyzed 1998 data from inspections of 13,693 nursing facilities representing virtually all U.S. nursing homes. They grouped deficiency citations issued by inspectors into three cat...

We study the portfolio selection problem of an investor who can optimally exert costly effort for more income. The possibility of generating more income, if necessary, increases the risk-taking appetite of the investor. We find the optimal allocation to the risky security as a proportion of financial wealth and as a proportion of the total wealth, defined as the combination of the financial wea...

Fraud propensity increases with the level of investor beliefs about industry prospects but decreases in the presence of extremely high beliefs. Evidence suggests that two mechanisms are at work: monitoring by investors, and short-term executive compensation, both ...

We develop a model to illustrate that controlling shareholders choose the level of investor protection that maximizes their own interests. Controlling shareholders in companies with complicated control structures can easily extract private benefits and are thus reluctant to enhance investor protection which would necessitate increased transparency. In contrast, controlling shareholders in compa...

In addition to their direct effects, episodes of financial instability may decrease investor confidence. Measuring the impact of a crisis on investor confidence is complicated by the fact that it is difficult to disentangle the effect of investor confidence from coincident direct effects of the crisis. In order to isolate the effects of financial crises on investor confidence, we study the inve...
