Nations engage in international trade because of difference in?

Nations engage in international trade because of the differences in the comparative cost of producing goods and services. Comparative cost refers to the ability of a nation to produce goods and services at a lower opportunity cost compared to other nations. Opportunity cost is the cost of foregone production of one good or service when producing another. For example, suppose country A can produce 100 units of wheat or 50 units of cloth with the same resources. In contrast, country B can produce 100 units of wheat or 40 units of cloth with the same resources. In this case, country A has a comparative advantage in producing cloth because it can produce more cloth (50 units) than country B (40 units) when given the same resources. As a result of this difference in comparative cost, country A can specialize in producing cloth and trade with country B, which can specialize in producing wheat. This allows both countries to benefit from the trade, as they can obtain more of both goods than they could produce on their own. Absolute cost, fixed cost, and variable cost are not directly related to the reasons for international trade. Instead, comparative cost is the key factor that explains why countries trade with each other.
