Extensive interest in business ethics has developed accompanied by an increase in empirical research on the determinants of unethical conduct. In setting forth the theory of reasoned action, Fishbein and Ajzen (1975) maintained that research attention on such variables as personality traits and demographic characteristics is misplaced and, instead, researchers should focus on behavioral intentions and the beliefs that shape those intentions. This study summarizes business ethics research which tests the theory of reasoned action and suggests directions for further research.
