Absolute and Comparative Advantage Absolute Advantage The producer that can produce the most output OR requires the least amount of inputs (resources) Ex: Papa John has an absolute advantage in pizzas because he can produce 100 and Ronald can only make 20. Comparative Advantage The producer with the lowest opportunity cost. Ex: Ronald has a comparative advantage in burgers because he has a lowest PER UNIT opportunity cost. 14 Countries should trade if they have a relatively lower opportunity cost. They should specialize in the good that is “cheaper” for them to produce. Essential Question: What goods and services should an economy produce?
