Decisional Power in Group Decision Making: A Note on the Allocation of Group Members' Weights in the Multiplicative AHP and SMART

Many complex decisions are made in a group environment, where the decision is made jointly by a committee or group structure. The individual group members are often not equally qualified to contribute equitably to the decision process, or may have different saliences (desires) to influence the decision. A quantitative knowledge of the players' decisional power is useful for better understanding of the group decision process, and could even be used in weighted voting within the group structure. We adapt the REMBRANDT suite of decision models (multiplicative AHP and SMART) to measure decisional power in groups, and we generalise this to cater for the case where power itself is deemed to be multidimensional in nature, and the case of uncertain subjective judgements of power amongst group members.     

An empirical study of ethical predispositions

Using a two-part instrument consisting of eight vignettes and twenty character traits, the study sampled 141 employees of a mid-west financial firm regarding their predispositions to prefer utilitarian or formalist forms of ethical reasoning. In contrast with earlier studies, we found that these respondents did not prefer utilitarian reasoning. Several other hypotheses were tested involving the relationship between (1) people's preferences for certain types of solutions to issues and (2) the forms of reasoning they use to arrive at those solutions; the nature of the relationship between utilitarian and formalist categories; and the possibility of measuring ethical predispositions using different methods.

Does lower-stage ethical reasoning emerge in more familiar contexts?

Four real-life dilemma cases collected from Hong Kong managers were included, along with two other cases previously used by Weber (1991), in an instrument designed to assess ethical reasoning capacity. This was completed by 86 part-time post-graduate students, all of whom were managers with at least four years working experience. Respondents' measured ethical reasoning capacity appeared to be at least as high as comparable samples in the U.S.A. The mean ethical reasoning stage varied between cases. Contrary to expectations, the unfamiliarityper se of a case did not affect ethical reasoning which instead tended toward higher measured stages when issues of public hazard or environmental pollution were introduced, and toward lower measured stages where personal or family finances were at stake. Two methodological points were made signalling the need for caution in research of this kind. First, because of reservations about the adequacy of the standard Kohlbergian model of ethical reasoning development, a scoring guide based on a revised Kohlbergian model of ethical reasoning was used to analyze the replies, rendering comparisons with other samples inexact. Second, the possible phenomenon of quasi Stage Five reasoning renders problematic the identification of true Stage Five ethical reasoning.Robin Snell directs the M.B.A. at the City University of Hong Kong, where he is University Senior Lecturer.

A Study on Aggregation of TOPSIS Ideal Solutions for Group Decision-Making

The technique for order preference by similarity to ideal solution (TOPSIS) has become a popular multi-criteria decision making (MCDM) technique, since it has a comprehensible theoretical structure and is able to provide an exact model for decision making. For the use of TOPSIS in group decisions, the common approaches in aggregating individual decision makers’ judgments are the geometric and the arithmetic mean methods, although these are too intuitive and do not consider either preference levels or preference priorities among alternatives for individual decision makers. In this paper, a TOPSIS group decision aggregation model is proposed in which the construction consists of three stages: (1) The weight differences are calculated first as the degrees of preferences among different alternatives for each decision maker; (2) The alternative priorities are then derived, and the highest one can be denoted as the degree to which a decision maker wants his most favorite alternative to be chosen; (3) The group ideal solutions approach in TOPSIS is used for the aggregation of similarities obtained from different decision makers. A comparative analysis is performed, and the proposed aggregation model seems to be more satisfactory than the traditional aggregation model for solving compromise-oriented decision problems.     

Using the Analytical Hierarchy Process (AHP) to Construct a Measure of the Magnitude of Consequences Component of Moral Intensity

The purpose of this work is to elaborate an empirically grounded mathematical model of the magnitude of consequences component of “moral intensity” (Jones, Academy of Management Review 16(2),366, 1991) that can be used to evaluate different ethical situations. The model is built using the analytical hierarchy process (AHP) (Saaty, The Analytic Hierarchy Process, 1980) and empirical data from the legal profession. One contribution of our work is that it illustrates how AHP can be applied in the field of ethics. Following a review of the literature, we discuss the development of the model. We then illustrate how the model can be used to rank-order three well-known ethical reasoning cases in terms of the magnitude of consequences. The work concludes with implications for theory, practice, and future research. Specifically we discuss how this work extends the previous work by Collins (Journal of Business Ethics 8, 1, 1989) regarding the nature of harm variable. We also discuss the contribution this work makes in the development of ethical scenarios used to test hypotheses in the field of business ethics. Finally, we discuss how the model can be used for after-action review, contribute to organizational learning, train employees in ethical reasoning, and aid in the design and development of decision support systems that support ethical reasoning.     

Consideration of the Role of Guanxi in the Ethical Judgments of Chinese Managers

The importance of personal connections and relationships, or guanxi when doing business with the Chinese is widely acknowledged amongst Western academics and business managers alike. However, aspects of guanxi-related behaviours in the workplace are often misunderstood by Westerners with some going so far as to equate guanxi with forms of corruption. This study extends earlier study of Tan and Snell: 2002, Journal of Business Ethics 41(December), 361–384) in its investigation of the underlying modes of moral reasoning in ethical decisions relating to aspects of guanxi, amongst Hong Kong managers. Managers’ ethical judgements and underlying moral reasoning relating to a series of guanxi-related behaviours were recorded. Content analysis yielded categories that correspond with categories of moral reasoning described in Kohlberg’s (1969, Handbook of Socialization Theory and Research, Rand McNally, Chicago, pp. 347–480) model. As hypothesised, it was found that harsher ethical evaluations of guanxi-related behaviours were positively correlated with the stage of moral reasoning. The most common types of reasoning were those corresponding to Kohlberg’s stages four and five which relate to moral reasoning based on law and order, and on reason rather than emotion. Stage 6, concerned with more universalistic approaches to moral reasoning, was utilised considerably less, consistent with popularly held beliefs of the relativistic nature of Chinese ethics.     

Enhancing Arthur Andersen business ethics vignettes: Group discussions using cooperative/collaborative learning techniques

Arthur Anderson & Co. has made a significant contribution to assist and encourage the teaching of business ethics. They provided assistance initially through workshops and curriculum materials; currently they are using campus coordinators to disseminate information and materials. The curriculum materials can be used by the instructor to assist students in practicing their moral reasoning skills and cover four academic areas: Accounting, Finance, Marketing, and Management. These materials include business ethics video vignettes, suggestions on presentation methods, guidelines for implementing a stakeholders' analysis approach to ethical reasoning, and possible discussion questions. The vignettes present ethical dilemmas that persons may encounter in entry level positions. We have used the vignettes, the accompanying discussion questions, and the suggested stakeholder analysis in class presentations. This paper presents a discussion of the basic concepts associated with cooperative learning, an example of the implementation of cooperative learning techniques using the Arthur Andersen Accounting Ethics Vignettes, and empirical results of the influence of these particular group discussions on the students' ethical responses. We did not attempt to measure whether the individuals' moral levels changed, but whether the group discussions stimulated any changes in the students attitudes toward the particular ethical dilemma they viewed.Lucia E.

Group Development (I): A Review and Synthesis of Development Models

This is the first of two parts that examine the issue of group development and its impact on the study design of group support systems (GSS). We review the various models of group development, analyze the sources of differences among these models, and synthesize common themes across various models. The paper concludes with a meta-framework for understanding group development; this framework highlights the two areas of focus that have dominated group development research in the past: group processes and outcomes. The second paper will build on the ideas developed here and discuss the implications of group development for GSS research.Previous research on group behavior suggests that groups change over time; patterns of change, referred to as group development models, have been an important area of study for the past four decades. For the first three of these decades, unitary models of group development were very popular; that is, the notion that all groups go through a certain series of predefined stages. In the last decade, however, researchers have cast doubt on such unitary models of group development. Nonsequential models that recognize the uniqueness of each group (and consequently reject the idea of a single, predetermined series of stages) have become increasingly popular. This paper examines the implications of these issues for researchers and managers of groups. It also attempts to serve as the foundation for the propositions developed in the next paper, in which the relevance of group development for GSS research and practice are discussed.     

An Exploratory Study of Chinese Accounting Students’ and Auditors’ Audit-specific Ethical Reasoning

This study uses three audit-specific ethical dilemmas to assess the level of ethical reasoning between Chinese accounting students (as proxies for new entrants to the auditing profession) and experienced auditors. A sample of U.S. accounting students is used as a base for comparison. Consistent with expectations based on particularly salient aspects of Chinese national culture, we find the Chinese students’ levels of ethical reasoning to be significantly lower than those of their U.S. counterparts in the two cases that invoked these cultural attributes. In contrast, the Chinese students’ level of ethical reasoning is slightly higher than that of the U.S. students in the third, control case. We further find that the Chinese auditors’ levels of ethical reasoning are even lower than those of the Chinese students in two cases, while not being significantly different in the third. Together, these findings suggest that cross-national differences in auditors’ ethical reasoning depend on the nature of the ethical dilemma and caution against wholesale inferences about ethical reasoning levels in China.     

A Progressive Search for a Group Ranking with Robust Conclusions on Prudent Orders

We consider the problem where rankings, provided for instance by a group of evaluators, have to be combined into a common group ranking. In such a context, Arrow and Raynaud suggested that the compromise ranking should be a prudent order. In general, a prudent order is not unique. That is why, we propose to manage this possible multiplicity of compromise solutions by computing robust conclusions. This allows for a progressive refinement of the decision model and supports the group to eventually select one group ranking. The approach is illustrated on a problem where a group of junior researchers has to agree on a ranking of research domains.     

Preemption in Capacity and Price Determination: A Study of Endogenous Timing of Decisions for Homogeneous Markets

Endogenous timing can help in deriving the time structure of decision making instead of assuming it as exogenously given. In our study we consider a homogeneous market where, as in the model of Kreps and Scheinkman (Bell Journal of Economics, 14 (1983), pp. 326–37), sellers determine ‘sales capacities’ before prices. Sellers must serve customers, but at higher costs when demand exceeds ‘capacity’. Our model allows for preemption in ‘capacity’ as well as in price determination. Since preemption means to decide before the random choice of cost parameters reflecting the stochastic nature of (excess) ‘capacity’ costs, preemptive commitments are not obviously better timing dispositions.     

The Relationship Between Pharmacists' Tenure in the Community Setting and Moral Reasoning

Objective: To explore the relationship between pharmacists' tenure in the community setting and their moral reasoning abilities. Design: Systematic random sample design. Setting: A large southeastern city in the United States. Participants:450 independent and chain community pharmacists identified from the state board of pharmacy list of licenced community pharmacists. Interventions: A mailed questionnaire that included a well-known moral reasoning instrument and collected demographic information. Main Outcome Measures: Moral Reasoning abilities and tenure of community pharmacists. Results: As a group, community pharmacists with greater years of tenure in community practice scored significantly lower on moral reasoning than those pharmacists with fewer years of tenure (p = 0.016). Conclusion: Four plausible explanations for the results are given including: a) a selection of lower ethical reasoners and/or an exodus of higher ethical reasoners from the community setting; b) a retrogression in the moral reasoning skills as community pharmacists obtain tenure in this setting; c) differences between the low and high moral reasoning groups may be due to a cohort effect; and d) the obtained practitioner sample may not have been representative of the population of community pharmacists.     

A Fuzzy Multi-Criteria Decision Making Model for IS Student Group Project Assessment

To accommodate the criterion-referenced student group project assessment approach, this paper proposes a fuzzy group Multi-Criteria Decision Making (MCDM) model. The proposed model can be used to solve student group project assessment problem in particular and generic MCDM problems in general, where the criteria used are often different and can be scored with multiple preference formats. The proposed fuzzy group MCDM model supports seven different preference formats, including preference ordering, utility vector, linguistic term vector, selected subset, fuzzy selected subset, fuzzy preference relation, and normal preference relation. It has been firstly used in the context of Information Systems (IS) student group project assessment.     

Human Rights,Transnational Corporations and Embedded Liberalism: What Chance Consensus?

I assessed change in students’ moral reasoning following five 75-min classes on business ethics and two assignments utilizing a novel pedagogical approach designed to foster ethical reasoning skills. To minimize threats to validity present in previous studies, an untreated control group design with pre- and post-training measures was used. Training (n = 114) and control (n = 76) groups comprised freshmen business majors who completed the Defining Issues Test before and after the training. Results showed that, controlling for pre-training levels of moral reasoning, students in the training group demonstrated higher levels of post-training principled moral judgment than students in the control group.     

Why buy new when one can share? Exploring collaborative consumption motivations for consumer goods

The notion of collaborative consumption or sharing economy—where consumers share access to ownership of properties such as cars, clothes and accommodations—has gained tremendous popularity in recent years. Development of communication technologies and peer‐to‐peer communities has enabled consumers to coordinate sharing activities through various online platforms. Collaborative consumption involves sharing of both intangible (e.g., music, space and car rides) and tangible assets (e.g., household items, clothes and furniture). Activities such as renting, swapping, trading and purchasing/selling used consumer goods are included in the latter. Despite increasing academic attention on collaborative consumption, little research has been pursued in the context of consumer goods. The nature of consumption for tangible goods can be entirely different from that of intangible goods because people can exercise greater control over tangible goods, which results in greater psychological ownership than that for intangible goods. To address this gap, the objective of this study is to develop a scale that examines consumer motivations for collaborative consumption of consumer goods. Following Churchill's paradigm of scale development, the procedures of scale item generation, purification and validation were conducted via in‐depth interviews, literature review and surveys. The study identified five underlying dimensions of collaborative consumption of consumer goods: concern‐for‐sustainability, social, variety‐seeking, fun and cost‐saving. Study findings and implications are discussed, and future research avenues are suggested.     

Business ethics: Restrictive or empowering?

There is a tendency in the business ethics literature to think of ethics in restrictive terms: what one should not do, and how to control this. Drawing on Lawrence Kohlberg's theory of moral development, the paper focuses on, and draws attention to, another more positive aspect of ethics: the capacity of ethics to inspire and empower individuals, as well as groups. To understand and facilitate such empowerment, it is argued that it is necessary to move beyond Kohlberg's justice reasoning so as to appreciate the value and importance of feeling and care. Accordingly, we draw upon case study material to review the meaning of Kohlberg's higher stages — 5, 6 and 7 — to question the meaning of ethical reasoning. With such deeper understanding of particular ethical codes or practices, it is thought that members of organisations may come closer to thespirit, as opposed to the letter, of ethical conduct in organisations. This, we argue, is consistent with the degree of trust and integrity demanded by leaner, post-bureaucratic ways of organizing and conducting business as well as being personally beneficial to the people involved.Bjørn Kjonstad has recently completed his Masters dissertation.

Ethical Reasoning and the Use of Insider Information in Stock Trading

The cognitive developmental theory of ethics suggests that there is a positive relationship between ethical reasoning and ethical behavior. In this study, we trained a sample of accounting and finance students in performing competitive stock trading in our state-of-the-art trading room. The subjects then performed trading of stocks under two experimental conditions: insider information, and no-insider information where significant performance-based financial awards were at stake. We also administered the Defining Issues Test (DIT). Ethical behavior, as the dependent variable was measured in a binary scale: whether the subjects used insider information for trading of stocks or not. Ethical reasoning as measured by the DIT P-score indicated statistically significant effect on ethical behavior. The results have important implications for recruitment and training of professionals engaged in the use of financial markets for securities trading.     

Improving Consistency for DIT Results Using Cluster Analysis

In this article, cluster analysis is used to explore the conflicting results reported when the Defining Issues Test is used to explain moral reasoning ability in business situations. Using a convenience sample, gender, age, work experience, and ethics training were examined to determine their impact on the level of moral reasoning ability as measured by the Defining Issues Test. Using the whole sample, a significant difference was found for average P scores reported for males and females, but no significant differences were found based on age, work experience, and ethics training. However, the sample fell into distinct clusters that identified distinct male and female groupings. While females naturally fell into two distinct high- and low-moral reasoning ability clusters, male clusters were dominated more by work experience and ethics training. Clearly there are other factors mitigating the level of moral reasoning ability for males which require further exploration. The findings suggest that while the P score provides an initial point of comparison, the real benefit to the test is in exploring what is different for males and females in terms of training needs, and the impact of work experience on the moral reasoning ability, and most importantly, how to make ethics training enticing. Recommendations for future research are also discussed. Carmel Herington is a senior lecturer in the Department of Marketing, Griffith University Gold Coast Campus, Australia.

How group and perceiver characteristics affect collective blame following counterproductive work behavior

Two experimental studies, based on a model using a novel integration of theories, provide evidence that collective blame, the assignment of blame to members of a group besides the member(s) who directly caused a misdeed, in the aftermath of counterproductive work behavior (CWB) is higher when a group of coworkers is perceived as a single entity. Further, the studies consistently show that this relationship is mediated by inferences about both indirect causality and common blameworthy traits among group members. These findings extend prior research, which has not considered mediation in this relationship by dual inferences. Additionally, perceivers’ implicit theories about people's character were found to moderate the inferences they favor, with inferences about indirect causality versus common traits favored by perceivers with implicit theories that people's character is malleable versus fixed, respectively. These findings extend prior research by empirically supporting the notion that the nature of perceivers’ implicit theories about people's character is related to why they perceive a group to be a single entity. The findings, future directions and implications of improved understanding of the assignment of collective blame following CWB are discussed.     

Actual and Perceived Sharing of Ethical Reasoning and Moral Intent Among In-Group and Out-Group Members

Despite an extensive amount of research studying the influence of significant others on an individual's ethical behavior, researchers have not examined this variable in the context of organizational group boundaries. This study tests actual and perceptual sharing and variation in ethical reasoning and moral intent within and across functional groups in an organization. Integrating theory on ethical behavior, group dynamics, and culture, it is proposed that organizational structure affects cognitive structure. Departmental boundaries create stronger social ties within the group as well as intergroup biases between the groups. Thus individuals will be more likely to share in ethical reasoning and moral intent with members of their own functional group (in-group) than with members of other functional groups (out-group). Additionally, they will perceive that they are more likely to share in ethical reasoning and moral intent with in-group members than with out-group members. Responding to two versions of two ethical scenarios, respondents contrasted their own ethical behavior to their expected ethical behavior of in-group and out-group members. Empirical results confirmed the hypotheses. Organizational group boundaries create actual as well as perceptual sharing and variation in ethical reasoning and moral intent. Furthermore, when comparing perceptual sharing to actual sharing, results show that individuals understate their sharing of ethical reasoning and moral intent with out-group members and overstate their sharing with in-group members. As organizational boundaries can create actual and perceived differences between groups that could lead to inter-group conflict, suggestions for management focus on removing or blurring inter-group boundaries.
