He was one of the most influential of the classical economists, along with Thomas Malthus, Adam Smith, and James Mill. Perhaps his most important legacy is his theory of comparative advantage, which suggests that a nation should concentrate its resources solely in industries where it is most internationally competitive and trade with other countries to obtain products no longer produced nationally."@en . . . .
