International trade theories explain the reasons and patterns behind trade between nations. The Ricardian theory emphasizes comparative advantage, suggesting countries should specialize in producing goods they can make most efficiently relative to others. The Heckscher-Ohlin theory expands on this by arguing that nations export products that use their abundant resources intensively and import goods requiring resources in short supply, highlighting the role of factor endowments like labor and capital.

What is the Ricardian theory of international trade?
It explains trade through differences in country productivity. Nations specialize in goods they can produce most efficiently relative to others (comparative advantage) and trade to increase overall output.
What is comparative advantage and how does it differ from absolute advantage?
Comparative advantage focuses on lower relative opportunity costs, not being the best at everything. A country can benefit from trade even if it has no absolute advantage in any good, as long as it sacrifices less of one good to produce another.
How does the Heckscher-Ohlin theory explain trade patterns?
It attributes trade to differences in factor endowments (capital vs. labor). Countries export goods that intensively use their abundant factor and import goods that use their scarce factor, which tends to partially equalize factor prices.
What are common criticisms or limitations of these theories?
Assumes perfect competition, identical technologies, and no transport costs; ignores economies of scale and dynamic effects; empirical tests (e.g., the Leontief paradox) sometimes contradict the predictions.
