HSC Economics — Topic 1
Comparative Advantage — Flashcards & Quiz
Comparative advantage is the foundation of trade theory in HSC Economics Topic 1: Global Economy. You need to distinguish it from absolute advantage, calculate opportunity cost from a production possibility table, and explain why specialisation and trade make both economies better off — even when one is more productive at everything. Australian context matters: examiners often ask why Australia specialises in resources and agriculture and imports manufactures. Be ready to evaluate the limitations of the model in a real, frictional world.

Q1: What is comparative advantage?
Comparative advantage is the ability of a country to produce a good or service at a lower opportunity cost than another country. It explains why international trade benefits all countries, even when one country has an absolute advantage in producing all goods. Comparative advantage forms the theoretical basis for free trade and specialisation. Countries should specialise in producing goods where they have the lowest opportunity cost and trade for other goods.
Sample Quiz Questions
Q1: Comparative advantage is based on differences in opportunity costs rather than absolute efficiency.
Answer: TRUE
Comparative advantage depends on which country has the lower opportunity cost for producing a good, not which country is absolutely more efficient. Even if one country is more efficient at producing everything (has absolute advantage in all goods), both countries can still benefit from trade by specialising according to their comparative advantages (lowest relative opportunity costs).
