Comparative advantage.

Explanation:

Comparative advantage in economics is the ability of an individual or country to produce a specific good or service at a lower opportunity cost better than another individual or country.

The comparative advantage gives a country a stronger sales margin than their competitors as they are able to sell their specific products or render their peculiar services at a lower opportunity cost.

In 1817, David Ricardo who is an english political economist talked about the law of comparative advantage in his book “On the Principles of Political Economy and Taxation." Also, the principle of comparative advantage states that, nations (countries) can become better off than their contemporaries through the process of specializing in what they know how to produce or do best.

This simply means that, any country applying the principle of comparative advantage, would enjoy an increase in output and consequently, a boost in their Gross Domestic Products (GDP).

In general, individuals and nations should specialize in producing those goods for which they have a comparative advantage.
