What is the primary effect of comparative advantage on trade?

The primary effect of comparative advantage on trade is that it enhances economic benefits for both parties involved. When countries or individuals specialize in the production of goods or services where they have a comparative advantage—meaning they can produce these more efficiently relative to other goods—they can trade with others who have different comparative advantages. This specialization allows all parties to focus on what they produce best, leading to an increase in overall efficiency and output.

As a result, trading based on comparative advantages enables countries to obtain a greater variety of goods and services at lower opportunity costs. This mutual benefit is a key principle in economics, driving both domestic and international trade. By focusing on their strengths, both parties can enjoy a larger total quantity of goods than they would be able to produce on their own, thus enhancing welfare and economic growth.

Other options do not accurately reflect the fundamental benefits of comparative advantage. While reducing dependency on imports might be a potential outcome in certain scenarios, it is not the primary benefit of comparative advantage in trade. Similarly, claims about lowering the quality of goods or decreasing competitive markets do not align with the concept of comparative advantage, which, rather, encourages competition and innovation through specialization and trade.
