This article begins with a detailed analysis of how the choice situation of a social contract for international business ethics can be constructed and justified. A choice situation is developed by analyzing conceptions of the multinational firm and the domain of international business. The result is a hypothetical negotiation between two fictional characters, J. Duncan Grey and Elizabeth Redd, who respectively represent the interests of businesses and communities seeking to engage in international trade. The negotiators agree on ethical principles governing (...) wages, the environment, and compliance social and cultural norms. These principles are then shown to rest in wide reflective equilibrium with considered moral judgments on international business ethics, which are drawn from international agreements, such as the UN Declaration on Human Rights, and voluntary business initiatives, such as the Global Sullivan Principles and the UN Global Compact.
