Why is Comparative Advantage Important?
The principle of comparative advantage explains why specialization and trade lead to a more efficient allocation of resources and higher global welfare. There are several key reasons why comparative advantage is important:-

Efficiency in Production
Specialization of countries or individuals on the basis of their comparative advantage can help in the better allocation of resources. For example, if one country is relatively better at producing a particular good (due to climate, labor force, or technology), it can specialize in that good, while the other country specializes in the good it can produce more efficiently. The outcome is higher total output and greater global economic welfare.
Higher Total Output
By specializing and trading based on comparative advantage, each producer increases his total output. This maximizes the total amount of goods available in the economy and improves living standards for everyone involved.
Gains from Trade
Even if a country is less efficient at producing both goods, it can still benefit from trade. For instance, if one country is much better at producing one good and the other country is better at producing a different good, both can benefit by specializing and exchanging

Lower Prices and Greater Variety of Goods
Comparative advantage is the reason why consumers get lower prices because it allows for producing goods in large quantities, which would otherwise be impossible to produce. As countries specialize and trade, they provide consumers with a wider variety of goods and services at lower prices than they would have otherwise.
