What is a comparative advantage in economics and how does it impact international trade?

A comparative advantage in economics refers to a country's ability to produce a good or service at a lower opportunity cost than Another Country. This means that a country can produce a good more efficiently than another country.

In international trade, countries with different comparative advantages can specialize in producing goods or services that they are most efficient at, and then trade with each other. This allows for increased efficiency and higher overall production levels, benefiting all countries involved. By focusing on producing what they are best at, countries can maximize their economic output and overall welfare through international trade.
