The ethical behavior of retail managers

A measure of ethics termed ethical behavior (EB) is postulated and tested across the moral philosophy types of managers. The findings suggest that certain managers, classified as rule deontologists, appear to rank higher on the EB scale than any other philosophy type tested.John Fraedrich is an Assistant Professor of Marketing at Southern Illinois University of Carbondale.

An empirical examination of three machiavellian concepts: Advertisers vs. the general public

This paper examines the perceived ethics of advertisers and the general public relative to three ethical concepts. Based on the survey findings, it can be concluded that with regard to the ethically-laden concepts of manipulation, exploitation, and deviousness, advertisers are perceptually as ethical as the general public. The research also clarifies some of the differences between ethics and Machiavellianism.John P. Fraedrich is an Assistant Professor of Marketing at Southern Illinois University at Carbondale.

Business ethics: A literature review with a focus on marketing ethics

In recent years, the business ethics literature has exploded in both volume and importance. Because of the sheer volume and diversity of this literature, a review article was deemed necessary to provide focus and clarity to the area. The present paper reviews the literature on business ethics with a special focus in marketing ethics. The literature is divided into normative and empirical sections, with more emphasis given to the latter. Even though the majority of the articles deal with the American reality, most of the knowledge gained is easily transferable to other nations.

The perceived role of ethics and social responsibility: A scale development

Marketers must first perceive ethics and social responsibility to be important before their behaviors are likely to become more ethical and reflect greater social responsibility. However, little research has been conducted concerning marketers' perceptions regarding the importance of ethics and social responsibility as components of business decisions. The purpose of this study is to develop a reliable and valid scale for measuring marketers' perceptions regarding the importance of ethics and social responsibility. The authors develop an instrument for the measurement of the perceived role of ethics and social responsibility (PRESOR). Evidence that the scale is valid is presented through the assessment of scale reliability, as well as content and predictive validity. Finally, future research needs and the value of this construct to marketing are discussed. Anusorn Singhapakdi is Associate Professor of Marketing at Old Dominion University.

The relative importance of social responsibility in determining organizational effectiveness: Student responses II

This paper, Study II, is the second in a series of papers investigating the relative importance of social responsibility criteria in determining organizational effectiveness, using student samples. A revised version of the Organizational Effectiveness Menu was used as a questionnaire with a sample of 182 senior undergraduate and the MBA students from three universities. Each respondent was asked to rate the importance of the criteria from a manager's perspective. The results support the earlier findings that students responding as managers rate social responsibility criteria, individually and collectively, among the least important of the potential determinants of organizational effectiveness.Dr. Kenneth L.

Consumer Ethics: A Cross-Cultural Study of the Ethical Beliefs of Turkish and American Consumers

The ethical climate in Turkey is beset by ethical problems. Bribery, environmental pollution, tax frauds, deceptive advertising, production of unsafe products, and the ethical violations that involved politicians and business professionals are just a few examples. The purpose of this study is to compare and contrast the ethical beliefs of American and Turkish consumers using the Ethical Position Questionnaire (EPQ) of Forsyth (1980), the Machiavellianism scale, and the Consumer Ethical Practices of Muncy and Vitell questionnaire (MVQ). A sample of 376 subjects that consists of American consumers (n = 188) and Turkish consumers (n = 199) was used to compare the ethical beliefs and practices of the two samples. The MANOVA results for the two nationality groups found that five out of six criterion variables differed between the two groups. The implications of this study are intended to assist marketers to develop strategies that suit a particular market and lessen their risk of entry. Mohammed Y.A.

Consumer ethics: An empirical investigation of factors influencing ethical judgments of the final consumer

Business and marketing ethics have come to the forefront in recent years. While consumers have been surveyed regarding their perceptions of ethical business and marketing practices, research has been minimal with regard to their ethical beliefs and ideologies. This research investigates general attitudes of consumers relative to business, government and people in general, and compares these attitudes to their beliefs concerning various questionable consumer practices. The results show that consumers' ethical beliefs are determined, in part, by who is at fault in the unethical behavior (the seller or the buyer). The results also indicate that those with a more positive attitude toward business are less likely to engage in questionable consumer practices, but one's attitudes toward salespeople, the government and people in general arenot related to the consumer's ethical beliefs.Scott J. Vitell is an Associate Professor and the Michael S. Starnes Professor of Marketing and Business Ethics at the University of Mississippi.

Identifying the gaps in ethical perceptions between managers and salespersons: A multidimensional approach

This research examines, in a general manner, the degree and character of perceptual congruity between salespeople and managers on ethical issues. Salespeople and managers from a diversity of organizations were presented with three scenarios having varying degrees of ethical content and were asked to evaluate the action of the individual in each scenario. Findings indicate that, in every instance, the participating managers tended (1) to be more critical of the action displayed in the scenarios, (2) to view the action as violating a sense of contract or promise, and (3) to view the action as less culturally acceptable than did the salespeople.Tony L.

A comparison of Nigerian to American views of bribery and extortion in international commerce

This study investigates the differences in the way bribery and extortion is perceived by two different cultures — American and Nigerian. Two hundred and forty American business students and one hundred and eighty Nigerian business students were presented with three scenarios describing a businessman offering a bribe to a government official and three scenarios describing a businessman being forced to pay a bribe to an official in order to do business. The Reidenbach-Robin instrument was used to measure the ethical reactions of the two samples to these scenarios. Results indicate that ethical reactions to bribery and extortion vary by (a) the nationality of the person offering the bribe, and (b) the country where the bribe is offered. In addition, Nigerians perceived some of the scenarios as being less unethical than did Americans. John Tsalikis is an Assistant Professor of Marketing at Florida International University.

Ethical decision making: An investigation of services marketing professionals

This study investigates the relative influences of professional values and selected demographic variables on the ethical perceptions of services marketing professionals. The relationship between ethical perceptions and ethical judgments of service marketers is also examined. The data were obtained from a mail survey of the American Marketing Association's professional members of service industries. The survey results indicate a positive relationship between a service professional's professional values and his/her perceptions of ethical problems. The results also suggest that ethical judgments of a service professional can be partially explained by his/her perceptions of ethical problems. Implications of the research findings were discussed.

Ethical perceptions of marketers: The interaction effects of machiavellianism and organizational ethical culture

This study examines the interaction effects of Machiavellianism and organizational ethical culture on two components of a marketer's ethical decision — perceptions of an ethical problem and perceptions of remedial alternatives. The results suggest that certain aspects of ethical perceptions are related to the interaction between Machiavellianism and organizational ethical culture.Anusorn Singhapakdi is Assistant Professor of Marketing at Old Dominion University.

The influence of non-anonymity deriving from feedback of research results on marketing professionals' research ethics judgements

The study examines, in the context of Crawford's (1970) study items, the influence of non-anonymity deriving from feedback of research results on marketing professionals' research ethics judgements, particularly that of response patterns (social desirability of responses) and item omissions. The results indicate that such non-anonymity does not significantly influence the social desirability of responses or item omissions — thus suggesting the appropriateness of its use to stimulate research ethics responses.

Consumer ethics: An investigation of the ethical beliefs of elderly consumers

Business and especially marketing ethics have come to the forefront in recent years. While consumers have been surveyed regarding their perceptions of ethical business and marketing practices, research has been minimal with regard to their perceptions of ethical consumer practices. In addition, few studies have examined the ethical beliefs of elderly consumers even though they are an important and rapidly growing segment. This research investigates the relationship between Machiavellianism, ethical ideology and ethical beliefs for elderly consumers. The results indicate that elderly consumers, while generally being more ethical than younger consumers, are diverse in their eithical beliefs. Dr Scott J.

The Role of Ethics Institutionalization in Influencing Organizational Commitment,Job Satisfaction,and Esprit de Corps

Given increasing ethical problems in business, many organizations have tried to control these problems by institutionalizing ethics such as by creating new ethics positions and formulating and enforcing codes of ethics. In this study, the impact of implicit and explicit forms of institutionalization of ethics on job satisfaction, esprit de corps, and organizational commitment for marketing professionals is investigated. Additionally, the influence of organizational socialization, ethical relativism, and age relative to each of the above organizational climate constructs is examined. Results indicate that at least one of the forms of institutionalization of ethics is a significant determinant of all three organizational climate constructs. However, while organizational socialization is a significant determinant of all three organizational climate variables, relativism is only significant in determining organizational commitment (in a negative direction) and age is only significant in determining job satisfaction.

Social inclusion as a marketing ethics correlate

The author examines, in the context of Litwin and Stringer's (1968) operationalization, the influence of social inclusion (organizational warmth and organizational identity) as a marketing ethics correlate. The results indicate that both organizational warmth and organizational identity underlie marketing professionals' ethical behavior. Furthermore, the influence pattern for each variable is consistent witha priori hypothesis.Ishmael P. Akaah is Associate Professor of Marketing at Wayne State University.

The effects of culture on ethical decision-making: An application of Hofstede's typology

This paper addresses a significant gap in the conceptualization of business ethics within different cultural influences. Though theoretical models of business ethics have recognized the importance of culture in ethical decision-making, few have examinedhow this influences ethical decision-making. Therefore, this paper develops propositions concerning the influence of various cultural dimensions on ethical decision-making using Hofstede's typology.Scott J.

The effectiveness of corporate communicative responses to accusations of unethical behavior

When corporations are accused of unethical behaviour by external actors, executives from those organizations are usually compelled to offer communicative responses to defend their corporate image. To demonstrate the effect that corporate executives' communicative responses have on third parties' perception of corporate image, we present the Corporate Communicative Response Model in this paper. Of the five potential communicative responses contained in this model (no response, denial, excuse, justification, and concession), results from our empirical test demonstrate that a concession is the most effective and robust communicative option.Jeffrey L.
