Comparative advantage is the ability to produce a good at a lower opportunity cost than another producer.

Answer basis

This answer is written for AP and IB Economics review, then connected to the related EconArena definition, practice questions, and playable economics game when one fits the concept.

Detailed Answer

Comparative advantage is the basis for mutually beneficial trade. Even if one country is more efficient at producing everything, it should specialize where its relative advantage is greatest. Both trading partners benefit by specializing in their comparative advantage and trading. This principle explains global trade patterns.

Example

The US might produce both cars and wheat more efficiently than Mexico. But if the US is relatively much better at cars, it should specialize in cars and import wheat—even though it could make wheat better than Mexico.
