Title Notes: Ch. 2.3 Comparative Advantage Absolute Advantage Absolute advantage is when someone is the best at doing something. to be able to make something using fewer resources than other production requires. Ex. America is the best at producing entertainment Ex. Colt Brennan (Hawaii) is the best at throwing touchdown passes Ex. Lance Armstrong is the best cyclist Are there cases where someone might be the best at something but it’s better for them to not do it?---- Yes!

Comparative Advantage Comparative advantage is when a person can produce something at a lower cost than anyone else if they specialize in that output. Specialization occurs when industrial workers focus on single tasks, enabling each one to be more efficient and productive Ex. Kobe can produce basketball points at lower cost compared to D'Angelo Russell.

In order to find people’s comparative advantage you DO NOT compare their absolute advantage. Instead compare their opportunity costs Why? Because we all know that a superhuman is way better than us at everything—but can they do it all? Nope. Therefore, we have to look at who has the lower opportunity cost to determine who should do what task (make which good).

Gains from specialization Absolute advantage Focuses on which of you uses the fewest resources Law of comparative advantage Focuses on what else those resources could have produced – that is, on the opportunity cost of those resources.

Exit Slip Provide one real life example of where specialization is used. Next, explain how comparative advantage plays a role in this specialization. Ex. Lakers for the NBA, championship. Each player specializes on a specific task to ensure they win games to win the championship. Kobe produces points to win games at a lower opportunity cost compared to his teammates.
