In trade, the principle that allows a country to produce a good at a lower opportunity cost than another is known as comparative advantage. This means that a country can make a specific product more efficiently compared to others, allowing it to trade for goods that it does not produce as well. For example, if Country A can produce cars using fewer resources than it takes to produce computers, while Country B is better at making computers, Country A should focus on making cars. By specializing in what each country does best, they can trade and both end up with more goods than if they tried to make everything themselves. This way, trade helps both countries benefit from their strengths.
