How is absolute advantage different from comparative advantage?
| Wheat per hour | Shirts per hour | |
|---|---|---|
| Country A | 6 | 3 |
| Country B | 1 | 2 |
Country A produces more of both, so it has an absolute advantage in both goods. But in opportunity cost terms, a shirt costs A two units of wheat and B only half a unit, so B has the comparative advantage in shirts. Smith (1776) argued for specializing in absolute advantages; Ricardo (1817) showed trade pays even without any absolute advantage.
Why does comparative advantage matter more?
Absolute advantage alone implies a country that's best at everything shouldn't trade—yet rich and poor countries trade constantly. Comparative advantage explains why. It's like a lawyer who types faster than her assistant but still hires one. Absolute advantage remains useful for explaining productivity and wage gaps.
