International trade most often takes place due to the unequal distribution of resources and differences in comparative advantage.
Step-by-step explanation:
International trade most often takes place because of the unequal distribution of resources and differences in comparative advantage. Comparative advantage refers to the ability of a country to produce a good or service at a lower opportunity cost than another country. When countries specialize in producing goods or services in which they have a comparative advantage, they can trade with other countries to obtain goods or services in which those countries have a comparative advantage.
