This paper summarizes three major approaches to the problem of business ethics. Comparisons and contrasts are drawn between the moralistic approach of Berhman, the social contract theory of Nash, and a comprehensive systems approach as articulated by Elbing. In the final section, some attempt is made to indicate how these models may be implemented into managerial policy decision making process by the use of group work and ascending communication. Some consideration of using organizational structure to implement ethical concerns is indicated.
