Ricardo, improving upon Adam Smith’s exposition, developed the theory of international trade based on what is known as the Principle of Comparative Advantage (Cost). David Ricardo, with the help of his comparative cost theory tried to illustrate that even if Portugal could produce wine and cloth more cheaply (in terms of labor hours) than England, it will be beneficial for Portugal to specialize in the production of wine, because she is comparatively more efficient in its production than cloth. Ricardo demonstrated that for two nations without input factor mobility, specialization and trade could result in increased total output and lower costs than if each nation tried to produce in isolation.
