International business ethics, as the term implies, cannot be national in character, anymore than international law can be national in character. Yet the analogy to law is as misleading as it is enlightening. For although we can speak of American, German or Japanese law, it is odd to speak of American, German or Japanese ethics. The reason is that ethics is usually thought to be universal. Hence there is simply ethics, not national ethics. Despite this, there is a sense that can be given to American business ethics or German business ethics. American business ethics does not refer to American as opposed to German ethics, but rather to the approach taken by those who do business ethics in the United States. What characterizes the American approach is not that it uses a special ethics or a national ethics, but that it is concerned with certain problems that are embedded in the American socio-economic-political system and faced by American business. German or Japanese business ethics differs from American business ethics in the cases and topics it deals with, in the different set of background institutions it takes for granted or investigates, and in the different culture, history, and social setting in which business operates.
The same is true of what is often called international business ethics insofar as we can distinguish American, German, Japanese approaches to it. International business ethics might refer simply to the comparison of business practices and their ethical evaluation in different countries; it might investigate whether there are in fact ethical norms commonly recognized in all countries that should govern international business and economic transactions, and if there are variations in ethical norms, whether multinational firms are bound by the ethical norms of their mother country, by the ethical norms of their host countries, by either, by both, or by neither. International business ethics might involve broad issues about the economic inequality of nations, the justice of the present international economic order, the ethical status and justifiability of such organizations as the World Bank and the International Monetary Fund and of their structures and practices, as well as the ethical dimensions of international debt, and the claimed economic dependence of some countries on others, or such global issues as the role of industry in the depletion of the ozone level.
