Answer:
Law of comparative advantage
Explanation:
Let's assume that Wakanda can produce either 10 bags of cotton or 10 bags of wine. While country x can produce either 5 bags of wine or 4 bags of cotton.
The opportunity cost of Wakanda producing either wine or cotton is one .
The opportunity cost of country X producing wine is 4 / 5 = 0.8 and the opportunity cost of producing cotton is 5 / 4 = 1.25
Wakanda should specialise in the production of production of cotton because it has a lower opportunity cost when compared with the other country.
Country x should specialise in wine production because it has a lower opportunity cost when compared with Wakanda.
This illustrates comparative advantage .
