Abstract
This work defines and illustrates examples of opportunity cost. It also defines and compares comparative and absolute advantage. Then, the work extends the narrative to compare these terms in today’s society.

Example 1:
| Potatoes| Chickens|
Michelle| 200| 50|
James| 80| 40|
* What is Michelle’s opportunity cost of producing potatoes?  (1 / 200) x 50 = 0.25 Chickens 200 Potatoes = 50 Chickens
1 Potato = 1/200 x 50=0.25 Chickens
Opportunity Costs= 0.25 Chickens
* What is Michelle’s opportunity cost of producing chickens? (1 / 50) x 200 = 4 Potatoes 50 Chickens = 200 Potatoes
1 Chicken = 1/50 x 200= 4 Potatoes
Opportunity Costs= 4 Potatoes
* What is James’ opportunity cost of producing potatoes? (1 / 80) x 40 = 0.5 Chicken 80 Potatoes = 40 Chickens
1 Potato = 1/80 x 40= 0.5 Chickens
Opportunity Costs= .5 Chickens
* What is James’ opportunity cost of producing chickens? (1 / 40) x 80 = 2 Potatoes 40 Chickens = 80 Potatoes
1 Chicken = 1/40 x 80 = 2 Potatoes
Opportunity Costs= 2 Potatoes
* Which person has an absolute advantage in which activities? * Michelle has an absolute advantage as she produces both more chickens and potatoes. * Which person has a comparative?

* James has a comparative advantage to produce chickens because his opportunity costs are lower than Michelle. But Michelle has a comparative advantage to produce potatoes because she has a lower comparative advantage to James. * Suppose that they are thinking of each specializing completely in the area in which they have a comparative advantage, and then trading at a rate of 2.5 pounds of potatoes for 1 chicken, would they each be better off? Explain.

James would specialize in Chickens.
1 Chicken = 2.5 Potato
Trade 80/2.25 Potatoes = 36 Chickens
Michelle would specialize in...
