A brief history of international trade thought: From pre-doctrinal contributions to the 21st century heterodox international economics

The present paper outlines the development of international trade thought, from the pre-doctrinal contributions of Greek philosophers and scholastic theologians, through the theories of the first schools of economic thought, and up to modern and contemporary trade theories. I follow filiations of ideas in a chronological order, and show how theoretical investigation into the causes and effects of international trade—and the rationale for government intervention—has evolved over the last two centuries.
