Summary

This topic explains absolute advantage and how specialization and trade increase world output using linear PPCs. It shows that when countries produce the goods they are more productive at, total production and consumption can rise, and it uses a two-country, two-good model to illustrate gains from trade and opportunity costs. The material is HL-only and prepares students to draw linear PPCs showing specialization and mutually beneficial exchange.
