What this lesson teaches
Comparative advantage means a country gains by specializing in what it can produce at the lowest opportunity cost and trading for the rest. Trade barriers such as tariffs and quotas raise the cost of imports to protect domestic producers but can also raise prices for consumers. Exchange rates set how much one currency is worth in another and shape the price of traded goods.
Worked example
The United States imports most of its coffee because its climate makes domestic coffee production far costlier than buying from countries like Colombia and Brazil, a clear case of comparative advantage.
Practice questions
- Define comparative advantage in your own words.
- Explain how a tariff on imported steel affects both domestic producers and consumers.
- Analyze how a weaker national currency could affect a country's exports and imports.

Comercio internacional y economía global
La ventaja comparativa significa que un país se beneficia al especializarse en lo que puede producir con el menor costo de oportunidad y comerciar por el resto. Las barreras comerciales, como los aranceles y las cuotas, elevan el costo de las importaciones para proteger a los productores nacionales, pero también pueden encarecer los precios para los consumidores. Los tipos de cambio establecen cuánto vale una moneda en términos de otra y determinan el precio de los bienes que se comercian.
Ejemplo: Estados Unidos importa la mayor parte de su café porque su clima hace que la producción nacional sea mucho más costosa que comprarlo a países como Colombia y Brasil, un caso claro de ventaja comparativa.
