Quizplus · Accepted Answer

David Ricardo's theory of comparative advantage states that international trade occurs because of differences in labor productivity. The theory suggests that countries should specialize in producing goods and services in which they have a comparative advantage (i.e., they can produce at a lower opportunity cost) and then trade with other countries for goods that they cannot produce as efficiently. The theory does not focus on natural resources, factor proportions, or firm-level advantages.
