📚 Quick Study Guide

  • ⏱️ Comparative advantage focuses on the opportunity cost of production.
  • 💡 A country (or individual) has a comparative advantage in producing a good or service if it can produce it at a lower opportunity cost than its competitors.
  • 🌍 International trade benefits all countries when each specializes in producing goods and services in which it has a comparative advantage.
  • 🧑‍🏫 Opportunity cost is what you give up to produce something else. It's calculated as the ratio of what you could produce instead.
  • ➗ Opportunity Cost of Good A = (Units of Good B that could be produced) / (Units of Good A that can be produced)
  • 💼 In everyday life, understanding your comparative advantage helps you focus on tasks where you're most efficient and valuable.
  • 📈 Specialization based on comparative advantage leads to increased overall production and economic growth.
