What is comparative advantage?

What is comparative advantage?

• A. The tendency for countries to import all goods they need.
• B. The practice of protecting domestic industries through tariffs.
• C. The ability of a country to produce goods and services at lower relative costs than other countries.
• D. The total amount of goods a country can produce given its resources.

Answer: (C)

Comparative advantage is about relative efficiency: a country can produce certain goods at lower opportunity costs than others. It’s not about being the best at everything or about total production alone. When a country focuses on the goods it gives up the least by producing, it can trade for the rest and both sides end up with more than they could produce on their own. This idea underlies why even nations that aren’t the best at producing any good still gain by specializing where their relative costs are lowest. That’s why the option describing producing goods and services at lower relative costs than other countries is the best fit. It captures the heart of comparative advantage: it's about cost trade-offs and using resources efficiently across nations, not about importing everything, protecting domestic industries, or simply the total amount a country could produce.
