Missiles 20 10 100 200 10 Coffee Absolute Advantage Given 100 resources, what can each country produce? • Production possibilities without trade • Trade allows specialization. US buys Coffee at < 10 resources. Colombia buys Missiles at < 20 resources. • Example: Coffee = 1, Missiles = 10. US trades 5 missiles (50 resources) for 50 coffee (50 resources) • Result: Both sides can achieve levels of consumption outside of the original production possibilities!
Wheat 100 50 5 10 Cars Comparative Advantage Given 100 resources, what can each country produce? • US has absolute advantage in both goods but 5 to 1 in wheat and only 2 to 1 in cars -- so has comparative advantage (bigger relative advantage) in wheat • UK has comparative advantage (smaller relative disadvantage) in cars (½ as productive rather than 20% as productive) • UK buys wheat at < 5 resources, US buys cars at < 10 resources • Example: Wheat = 1.5, Cars = 9. US sells 24 wheat (36 resources), buys 4 cars (36 resources)
