- David Ricardo developed the classical theory of comparative advantage in 1817 to explain why countries engage in international trade even when one country's workers are more efficient at producing every single good than workers in other countries.
-He held out the belief that the rate of profit for society as a whole depends on the amount of labor necessary to support the workers who farm "the most barren land that can still maintain agriculture" This model breaks land down into categories based on average fertility rates. The most fertile land naturally produces more food than land of poorer quality. As a result it commands a higher rent.

That is, economic truths should be arrived at by observing not only the immediate consequences—that is, benefits or liabilities—of an economic decision, but also by examining the long-term second and third consequences.
