IntroductionIt is well known that business people in general, are faced with numerous ethical dilemmas and pressures to compromise their personal ethics to achieve corporate goals. For example, Longenecker et al. (1988) found both entrepreneurs and other business people feel pressure to behave unethically. In response to ethical dilemmas, salespeople have requested that firms provide more guidelines, such as codes of ethics, to aid them in making ethical decisions (Dubinsky et al., 1980; Dubinsky and Levy, 1985). Therefore, given that the organizations provide the social context within which behavior takes place (Trevino 1986), it is top management's responsibility to develop, communicate, and enforce a well thought out corporate code of ethics.However, research is inconclusive regarding the effectiveness of the formal codes in changing attitudes and behavior. For example, Weaver and Ferrell (1977) found that the existence and enforcement of corporate policy may improve some ethical beliefs and behavior; while, Chonko and Hunt (1985) concluded based on respondent's perceptions that the existence of corporate or industry code of ethics, although necessary, seems, by itself, to be insufficient to prevent ethical problems in marketing management. A similar position was taken by Brenner and Molander (1977) and by Cressey and Moore (1983). However, the fact that a code of ethics is found in numerous models of ethical decision-making (Ferrell et al., 1989; Ferrell and Gresham, 1985; Trevino, 1986; Wotruba, 1990) implies continued research is called for in this area.With the exception of Weaver and Ferrell (1977) who investigated marketing managers, no other marketing studies have empirically investigated the relationship between a code of ethics and behavior. The need for continued empirical research regarding the effectiveness of codes of ethics has been revealed by Ferrell et al. (1989, p. 63) in their following statement, 'Studies analyzing the effect of codes on ethical decision making would be helpful in understanding the role of corporate culture.'Given that most research, thus far, has suggested that in one way or another, corporate codes of ethics are relevant and since there is a severe lack of empirical studies on the subject, the purpose of this paper is to provide an empirical case study that examines the relationship between a corporate code of ethics and sales force behavior., A case study of the southwest region sales force of an office equipment corporation determined the effects of a corporate code of ethics on sales force behavior. The results provide evidence that a corporate code of ethics which is well-communicated is correlated to ethical sales force behavior. Based on the study results, it was predicted that a sales force in such a setting would have better job performance and would derive greater satisfaction from their jobs. Suggestions for marketing practitioners were given.
