Which economic principle discusses the benefits arising from trade between countries?

The principle that specifically addresses the benefits arising from trade between countries is centered around the concept of gains from trade. This concept illustrates how countries can benefit from specializing in the production of goods and services in which they have a comparative advantage and subsequently trading with other nations. By engaging in trade, countries can access a variety of goods that may be produced more efficiently elsewhere, leading to an overall increase in economic welfare.

The idea of gains from trade emphasizes that when countries trade, they can consume more than they would be able to produce on their own, thus enhancing their overall economic output and improving living standards. This principle is fundamental to understanding international trade policies and economic relationships, as it provides a compelling argument for why nations pursue trade agreements and engagement in global markets.

While comparative advantage is certainly a key element in understanding how trade can be beneficial, it is the broader concept of gains from trade that encapsulates the overall economic benefits derived from such exchanges. Opportunity cost focuses on the cost of forgoing the next best alternative when making decisions, and trade barriers refer to governmental restrictions on trade that can hinder the benefits that arise from open trade, but they do not directly address the advantages arising from trade itself.
