1 янв 1772 г. - Comparative advantage is when a country produces a good or service for a lower opportunity cost than other countries. Opportunity cost measures a trade-off. A nation with a comparative advantage makes trade worth it. The benefits of buying their good or service outweigh the disadvantages. The country may not be the best at producing something, but the good or service has a low opportunity cost for other countries to import. It implies that trading is good for everyone including the poorer nations. (Лента времени)
