What does comparative advantage refer to?

Comparative advantage refers to the ability of an individual, firm, or country to produce a particular good or service at a lower opportunity cost than others. This concept is fundamental in economics as it explains how trade can benefit all parties involved, even if one has an absolute advantage in producing all goods. When one entity has a comparative advantage, it can specialize in producing that good or service, leading to more efficient resource allocation and greater overall output.

This principle encourages entities to focus on their most efficient production capabilities, allowing them to trade and benefit mutually, thus maximizing economic welfare. In contrast, the other options do not accurately reflect the definition of comparative advantage. For example, producing at a higher opportunity cost does not align with the idea of comparative advantage, which is focused on minimizing opportunity costs. Similarly, while larger economies may have certain advantages, that concept does not directly relate to opportunity costs. Lastly, the focus on domestic production over imports is more related to trade policies rather than the principles of comparative advantage.
