The ability of an individual, a firm, or a country to produce a good or service at a lower opportunity cost than competitors is known as COMPARATIVE ADVANTAGE, what makes it such a powerful insight?

Explanation:

The Heckscher Ohlin theory of comparative advantage states that a country must produce the goods for which they have an abundance of factors of production, e.g. countries with a lot of land can produce agricultural products. When a country is able to produce goods at a comparatively lower price than other countries, they will be able to trade and benefit from it.

Benefits from trade are obtained not by absolute advantages in the production of goods, but by producing goods with a comparative advantage, i.e. lower opportunity cost.

For example, country A can produce 100 bushels of corn and 50 bushels of wheat. Country B can produce 50 bushels of corn and 35 bushels of wheat.

Even though country A has an absolute advantage in the production of corn and wheat, it will benefit from trade only if it specializes in the production of corn and imports wheat. On the other hand, country B will benefit from trade if it specializes in the production of wheat and imports corn.
