What is the term for trade that occurs between different countries?

The term for trade that takes place between different countries is known as international trade. This concept involves the exchange of goods and services across national borders, allowing countries to import and export products that they may not produce as efficiently or at all.

International trade enables nations to benefit from comparative advantage, where countries specialize in producing certain goods more efficiently than others, ultimately leading to increased overall economic efficiency and a variety of consumer choices. This form of trade also fosters economic growth, as it opens up new markets for producers and provides consumers with access to products that may not be available domestically.

The other terms mentioned refer to different economic concepts. Economies of scale relate to cost advantages that enterprises obtain due to their scale of operation, which can lead to greater efficiency. Task utility is a measure of the value added by completing a specific task or function, and possession utility refers to the satisfaction gained from owning or controlling a product. None of these terms pertain directly to the exchange of goods and services between countries, making international trade the correct answer.
