Comparative advantage

Definition

Comparative advantage refers to the ability of a country, individual, or entity to produce a good or service at a lower opportunity cost than others. This concept is fundamental in international trade, as it explains how countries can benefit from specializing in the production of goods for which they have a comparative edge, leading to increased overall efficiency and trade gains.

Review Questions

• How does comparative advantage influence a country's decision on what goods to produce?
  • Comparative advantage influences a country's production choices by encouraging it to focus on goods for which it has the lowest opportunity cost.
