Comparative Advantage – Definition & Examples

Definition: The ability of a party to produce a good at a lower opportunity cost than another party.

Detailed Explanation

Comparative advantage is the basis for mutually beneficial trade, even if one country is better at producing everything (absolute advantage). Countries should specialize in goods where their opportunity cost is lowest, then trade. This increases total world output. The concept explains why rich and poor countries both benefit from trade.

Real-World Example

The US might be more productive than Vietnam in both software and clothing. But if the US is relatively much better at software, it should specialize there and import clothes from Vietnam—both benefit.
