Abstract
The notion that the firm, and economic activity in general, is inherently amoral is a central feature of positive economics that is also widely accepted in business ethics. Theories as disparate as stockholder and stakeholder theory both leave this central assumption unchallenged. Each theory argues for a different set of external ethical restrictions, but neither adequately provides an internal connection between business and the ethical rules business people are obliged to follow. This paper attempts to make this connection by arguing that the purpose of business is to produce a good or service for trade. Trade involves both a respect for individual autonomy and property rights and squarely places moral norms internal to the practice of business. Trade is not a contingent activity of business, it is a practice rule which also provides the common sense boundary between business and charity on the one hand, and crime on the other. Business and those who engage in it are, from the internal point of view, bound by the purpose of trade and not just the laws of the land.
