COMPARATIVE ADVANTAGEAccording to David Ricardo, whoever can make a product at the lowest opportunity cost should produce it.
To determine who has the lower opportunity cost we need to get our ratio to show for every one item produced what will be given up or what could have been produced using those resources.

Advantages of trade based on comparative advantage:
1. All countries benefit - obtain more goods than if they produced everything on their own
2. Interdependence between countries is greater, countries no longer produce everything themselves
3. Standard of living increases for all
