Trade Theories: Absolute & Comparative Advantage
Trade theories such as absolute and comparative advantage explain why countries engage in international trade. Absolute advantage occurs when a country can produce a good more efficiently than another. Comparative advantage, introduced by David Ricardo, suggests that even if one country is less efficient in producing all goods, it should specialize in goods where it has the lowest opportunity cost, enabling mutually beneficial trade and increased overall economic welfare.

❓ Frequently Asked Questions
What is absolute advantage?

Why do countries trade under comparative advantage?
Because each country specializes in goods with the lowest opportunity costs, increasing total world production and making both sides better off.
