How does international trade benefit countries if each country specializes in the good in which it has a comparative advantage?

International trade benefits countries when each country specializes in producing goods in which it has a comparative advantage because it allows for increased efficiency, higher productivity, and greater economic growth. This specialization enables countries to focus on producing goods they are most efficient at, leading to lower production costs and increased competitiveness in the global market. As a result, countries can trade their surplus goods for products they do not produce efficiently, leading to a more diverse and efficient allocation of resources globally.
