Calculating Comparative Advantage with Output and Input Methods Made Easy...I think.

One of the hardest concepts to intuitively understand in economics is Comparative Advantage. Seems like most of the time with students a deep understanding is elusive. It just takes practice and thought.

While we wait for those "AH HA!" moments, students still need to understand the "nuts and bolts" of the math behind the concept.  This can be elusive as well, especially for students who are not strong in math.

These two very short presentations will walk you through the basics so at least you can get the math right. It is important to get the "set-up" of the problems correct before proceeding with the math.

I hope this helps someone!
