A series of survey studies on corporations' institutionalization of ethics
has been done in the U.S. and Japan. Among them, one Japanese study suggest
s that company policy is the most influential factor in managers' ethical d
ecision-making and behavior. This empirical evidence suggests that, in japa
n, company efforts to institutionalize ethics are effective in improving bu
siness behavior. The author examines this by describing three case studies
of Japanese managers' ethical decision-making.
