The Principle of Comparative Advantage Comparative advantage is the ability of a person (or state, region, country) to perform an activity or produce a good or service at a lower opportunity cost than someone else (or some other state, region, or country).
Liz’s Smoothie Bar Lizzie can make smoothies or salads. Her production possibilities are as follows:
Measuring Liz’s Opportunity Cost It takes me 90 seconds to do one salad— 90 seconds that could have been used to make one smoothie. Thus: 1 smoothie = 1 salad and 1 salad = 1 smoothie
Joe’s Smoothie Bar Joe can make smoothies or salads. His production possibilities are as follows:
Measuring Joe’s Opportunity Cost It takes me 10 minutes make one smoothie—I could make 5 salads in 10 minutes. Thus: 1 salad = 1/5 smoothie and 1 smoothie = 5 salads
Absolute Advantage Notice that Liz has an absolute advantage over Joe— that is, she can make more salads and smoothies per hour. Does it follow there would be no advantages to specialization and trade?
Liz has the comparative advantage in smoothies, since she can make them at lower opportunity cost than Joe has the comparative advantage in salads—since he must sacrifice 1/5 smoothie per salad; whereas Liz must sacrifice 1 smoothie per salad.
Terms of Trade I am willing to trade if I can get more than one salad in exchange for one smoothie. I am willing to trade if I can get more than one fifth of a smoothie in exchange for one salad (or pay less than 5 salads 1 smoothie)
1 smoothie buys 2 salads Or: 2 salads buys one smoothie These terms are advantageous to both Liz and Joe!!
