The residual market factor,the APT,and mean-variance efficiency

The rapidly increasing volume of both published and unpublished work on the arbitrage pricing theory (APT) of Ross (1976) has given rise to a number of misunderstandings at the interface of theoretical and econometric work. In this article we extend the theoretical structure of our previous work (McElroy and Burmeister, 1985, 1988; Burmeister and McElroy, 1987, 1988) to provide a broad yet rigorous framework both for econometric estimation and for better economic interpretation of new empirical results. We begin with the case where allK factors are observed, and then present the second case ofK−1≡J observed APT factors and one unobserved factor, theresidual market factor introduced in McElroy and Burmeister (1985). The economic interpretations for equivalent specifications of this model are discussed, and we enumerate several immediate payoffs to these specifications. The main new results are concerned with the sometimes intricate relationships among APT models withK factors and APT models withK factors that are constrained to satisfy mean-variance efficiency restrictions. These results are not only of theoretical interest, but more importantly they provide the basis for econometric estimation and testing of nested hypotheses. These econometric issues are discussed in detail.     

Guide to the Ethics of Ex Parte Communications

Ex parte communications can become an administrative quagmire for anyone trying to deal with tribunals that regulate business matters. These communications involve contact between a decision maker and one party outside the presence of another, interested party. At a time when codes of ethics are enacted to make corporate financial officers and boards of directors more accountable to their stockholders, and thus, to restore the confidence of the investing public, it appears most important that administrative judges and hearing officers adhere strictly to their own Codes of Conduct. This article defines and explains ex parte contacts and consequent problems that might arise during administrative appeals. It is not the author’s intent to present the law of any specific jurisdiction, but to present a general overview of typical state law in the United States, a market of interest to many entrepreneurs and exporters worldwide.     

Are We Sending Mixed Messages? How Philosophical Naturalism Erodes Ethical Instruction

To develop critical thinking skills, higher order ethical reasoning, a better grasp of the implications of ethical decisions, and a basis for ethical knowledge, it is necessary to explore the philosophical premises foundational to one’s ethical persuasion. No philosophical premises are more important than those pertaining to the nature of human personhood and business’ responsibility to respect the inherent value of human beings. Philosophical naturalism assigns the essence of human personhood strictly to causal interactions of physical matter. Substance dualism, on the other hand, posits both a physical aspect and an immaterial substance to personhood, interacting within the totality of each being. This paper argues for the logical superiority of substance dualism in achieving the overriding objective of discerning ethical knowledge. Substance dualism offers a better explanation – and one that more closely follows the way most people commonly experience themselves and others–than naturalism for free agency and accountability, meaningful moral standards, confidence in knowing what ethical decisions to make, and the moral drive residing in conscience.

China's outward foreign direct investment

China's outward foreign direct investment (FDI) is steadily increasing. The United States is now a key target for China's outward FDI, and the response by the American public tends to fall at opposite ends of the spectrum: fever or fear. Chinese FDI in the United States faces challenges posed by its liability of foreignness in political, cultural, marketing, and technological aspects. Utilizing mini case studies, we herein examine the polarized responses to Chinese outward direct investment, its history, and the challenges faced by Chinese multinational corporations operating in or attempting to enter the U.S. market. Finally, strategy suggestions are proposed.     

Making compassion count: equal recognition and authentic involvement in mental health care

Compassionate care within mental health services is often taken for granted as something that can be made visible and authentic. However, recent government reports and policy suggest that we are far from providing compassionate care and may be more focused upon risk and surveillance. This paper will discuss the visibility of compassionate care and explore outcomes that consumers and practitioners could measure in practice. Separating the fact from fiction within compassionate care will make authentic involvement practices more visible and open to discussion around consumer collaboration. In a qualitative analysis of a small study with mental health consumers, compassion was found to be a major factor in whether consumers became more involved in their own health care. Demonstrating compassionate care may therefore also demonstrate consumer participation and engagement. This paper will argue that compassionate care can be observed in the relationships between practitioners and consumers that are collaborative and use presence and persistence as methods of practice. Emancipatory practices can be made more visible in mental health care in order to make compassion measurable and to encourage consumer participation and engagement.     

Violations of Service Fairness and Legal Ramifications: The Case of the Managed Care Industry

Adapted from Chan's (2000) model depicting success of litigation, this paper argues that with the application of various legislation, health maintenance organizations' (HMOs') violations of service fairness to each group: enrollees, physicians, and hospitals give rise to each group's lawsuits against the HMOs. Various authors (Bowen et al., 1999; Seiders and Berry, 1998) indicate that justice concepts such as distributive, procedural, and interactional justice can be applied to the area of service fairness. The violation of these underlying justice principles with HMOs' service unfairness to enrollees, physicians, and hospitals is examined. A general synopsis of the ethical issues in the managed care industry is provided. The various lawsuits launched by each group: enrollees, physicians, and hospitals together with the key statutes used are discussed. This paper also highlights the provisions and ramifications of the 11 April 2000 landmark agreement that Aetna made with Texas Attorney General John Cornyn to settle the 1998 lawsuit brought against the company. Lastly, the current ethical issues in the managed care industry are further discussed. The value of this paper can be adapted to the study of organizations' service fairness violations in other industries or in the educational, governmental, and not-for-profit sectors both nationally and internationally.     

Has bank holding companies' diversification affected their risk of failure?

The effect of nonbank activities on the riskiness of banking organizations is an important issue in capital regulation and deciding whether banking firms should be allowed to perform additional activities. This paper explores the potential effect of deregulation by examining the effect of existing nonbank subsidiaries on the riskiness of bank holding companies. The results provide no evidence to suggest that deregulation would increase banking organizations' risk and weak evidence that deregulation might decrease risk.
