A Solution Methodology for Probabilistic Capital Budgeting Problems Using Complex Utility Functions

Historically, the study of economic equipment replacement is primarily limited to that of a single machine or a single machining system. The replacement situation whereby machines under consideration are part of a large integrated system has received little attention. This paper proposes a framework, for the analysis of multiple-machine replacement within an integrated system context. The major difficulty of analyzing such a problem lies in the interactive nature of an integrated system; that is, how should the effects to the entire system be assessed as a result of alterations to one or more of its components. The emphasis of this work is on the issues regarding multiple machine replacement. A single-period model is utilized in order to simplify the presentation. A comprehensive example is also provided for illustration.     

How Do Playful People Play? Gendered and Racial Leisure Perspectives,Motives, and Preferences of College Students

Playfulness is an aspect of personality that predisposes individuals to reframe boring situations into more amusing ones for themselves. This study extends knowledge about the playfulness construct by contrasting college students who were high or low in playfulness relative to the activity preferences they make, the motives they have, and their perspectives on their leisure time. Significant differences were found in perspectives and motives but not in activity preferences, leading to the conclusion that playfulness relates more to how individuals view their leisure and what they seek than in what they do. Only minor differences due to gender or race were observed.     

The Provision of Other Services by Auditors: Independence and Pricing Issues

This research has three objectives: to identify the extent and level of other services provided by incumbent auditors in the Australian business environment; to examine pricing issues by investigating the relationship between fees for other services and audit fees; and to address the question of independence by (a) identifying whether the incidence of audit qualification is related to the level of other services purchased and (b) investigating whether there is a relationship between audit tenure and the level of other services provided. Information on audit fees, fees for other services, size, audit qualifications, industry and auditor (Big 8(6)/Non-Big 8(6)) was obtained from publicly available information for the majority of the top 500 Australian companies listed on the Australian stock exchange between 1986–1990. This study provides evidence that an increasing number of clients are purchasing other services from their auditor. A significant positive relationship between fees paid for other services and audit fees was also identified. No relationship was identified between the level of other services and the type of audit report issued or audit tenure, supporting the view that audit independence is not compromised by provision of the other services.     

Ethics, Governance and Risk Management: Lessons From Mirror Group Newspapers and Barings Bank

While corporate failures, such as Enron and WorldCom, have focused attention on issues of business ethics, corporate governance and risk management, there is nothing intrinsically new in the reasons behind their collapse. Neither is there anything fresh in the media's rush to identify a scapegoat. An examination of the financial collapse of Mirror Group Newspapers and Barings Bank, demonstrates failures within both these companies' corporate cultures and management systems, which allowed, if not encouraged, unethical behaviour by key individuals. It is argued that a combination of legislation, regulation, effective risk management and appropriate sanctions are needed, if such unethical behaviour, and resulting corporate failure, is to be prevented in future.     

Support for the Use of Deception Within the Work Environment: A Comparison of Israeli and United States Employee Attitudes

As businesses become more global, the opportunities for employees to work with individuals from different cultures increase. Research in cross-cultural interactions has increased in response to such changes. This research study considers employee attitudes and perceived organizational support for the use of deception within the work environment. In this study, two types of deception have been considered; deception for personal gain and deception for the organization's benefit. The reported likelihood for committing these two types of deception for United States and Israeli employees was gathered. The results indicate that United States employees are more likely to deceive others for personal gain than the Israeli employees. In addition, the results indicate that United States employees were more likely to perceive organizational support for the use of deception for personal gain than were the Israeli employees. No differences between the two samples were found for personal or organizational support for deception for the organization's benefit. Differences are explained using Hofstede's (1991) theory of international cultures.     

Ethical Decision-Making by Consumers: The Roles of Product Harm and Consumer Vulnerability

The primary purpose of this study was to examine the effects of perceptions of product harm and consumer vulnerability on ethical evaluations of target marketing strategies. We first established whether subjects are able to accurately judge the harmfulness of a product through labeling alone, and whether they could differentiate consumers who were more or less vulnerable. The results suggest that without the presence of a prime, subjects who depended on implicit memory or guess were able to detect differences in “sin” and “non-sin” products and consumer vulnerability, but were far less likely to be able to distinguish among high and low levels of product harm and consumer vulnerability. The inability to accurately identify high and low levels of product harm and consumer vulnerability impacted their perceptions of the ethicality of target marketing strategies, such that only four out of 18 target marketing strategies were judged as unethical. Thus, our findings contradict previous research that found subjects judged many more of the integrated strategies as unethical [Smith and Cooper-Martin, J Market 61(1997) 1]. Our results suggest that assessing ethical evaluations of strategies varying in product harm, and consumer vulnerability may only be relevant if consumers can accurately identify product harm.     

Criminal justice involvement and high school completion

This paper analyzes the relationships between juvenile justice system interactions and high school graduation. When controlling for a large set of observable and unobservable characteristics, arrested and incarcerated individuals are about 11 and 26 percentage points, respectively, less likely to graduate high school than non-arrested individuals. However, the effect of arrest is not robust to there being relatively little selection on unobservable characteristics. In contrast, the incarceration effect is less sensitive to such selection and therefore more likely to at least partially represent a real effect. The remainder of the paper explores the mechanisms underlying this incarceration effect, including hypotheses of an education impeding stigma and disruptions in human capital accumulation.     

Restaurant servers’ perceptions of customer tipping intentions

Customer reactions to service encounters have been studied with surprisingly little emphasis on how servers’ perceive customers. If tips are an incentive to reward service then beliefs about consumers’ tipping habits may impact service delivery. An extensive survey of restaurant servers revealed that regular patrons and males were thought to be the best tippers; teenagers the worst. Females perceived males, African-Americans and foreign customers to be better tippers than did males; self reported tip income for males was greater than for females. Server ethnicity was not a factor. Systematic monitoring of these server perceptions may ensure more homogeneous service delivery.
