The traditional military-territorial model of the nation state defines international duties in terms of protecting citizens' property from foreign threats. In this 1992 book about the principles of the US agricultural policy and foreign aid, Professor Thompson replaces this model with the notion of the trading state that sees its role in terms of the establishment of international institutions that stabilize and facilitate cultural and intellectual, as well as commercial, exchanges between nations. The argument focuses on protectionist challenges to foreign aid and development assistance programs, and engages with the views of a variety of economists, commodity organizations, and philosophers on world hunger and development. What emerges is a new interpretation of social contract theory that can determine goals for international trade and development policy.
