In an hour, liz can produce 30 smoothies or 30 salads. Liz"s opportunity cost of producing 1 smoothie is 1 salad. Liz"s opportunity cost of producing 1 salad is 1 smoothie. Liz"s customers buy salads and smoothies in equal number, so she produces 15 smoothies and 15 salads an hour. In an hour, joe can produce 6 smoothies or 30 salads. Joe"s opportunity cost of producing 1 smoothie is 5 salads. Joe"s opportunity cost of producing 1 salad is 1/5 smoothie. Joe"s spend 10 minutes making salads and 50 minutes making smoothies, so he produces 5 smoothies and 5 salads an hour. Liz"s absolute advantage: liz is three times as productive as joe, liz can produce 15 smoothies and 15 salads an hour whereas joe can produce only 5 smoothies and 5 salads an hour. Liz has an absolute advantage in producing smoothies and salads.

4. Your roommate Pat decides to help with the party. The amounts of brownies and cookies which can be produced in an hour (if all resources are devoted to that good) are shown by the following table:

YOU PAT

COOKIES PER HOUR 20 5

BROWNIES PER HOUR 40 20

Where both cookies and brownies are measured in units.

a. Who has an absolute advantage in producing brownies? Cookies?

b. For you, what is the opportunity cost of producing one brownie? Of one cookie?

c. For Pat, what is the opportunity cost of producing one brownie? Of one cookie?

d. Should you and Pat specialize? Who should produce what?

e. Suppose that you have so many guests that you have to split up the party into two rooms. You throw one party and Pat throws the other. What are the terms of trade? (At what rate would you each be willing to trade?)

f. Using graphs for both you and Pat, show that trade allows each of you to

achieve a point on your consumption possibilities curve which is greater than

your production possibilities curve. Be sure to label all curves and axes.

f. What is this principle called?

Suppose two people, Michelle and James each live alone in anisolated region. Both have the same resources available, and thegrow potatoes, and raise chickens. If Michelle devotes all herresources to growing potatoes, she can raise 200 pounds of potatoesa year. If she devotes all her resources to raising chickens, shecan raise 50 chickens per year. (If she apportions some resourcesto each, then she can produce any linear combination of chickensand potatoes that lies between those extreme points. If Jamesdevotes all his resources to growing potatoes, he can raise 80pounds of potatoes per year. If he devotes all his resourcesraising chickens, he can raise 40 chickens a year. ( If heapportions some resources to each, the he can produce any linearcombination of chickens and potatoes that lies between thoseextreme points).

1. What is Michelle's opportunity cost of producing potatoes?

2. What is Michelle's opportunity cost of producing chickens?

3. What is James' opportunity cost of producing potatoes?

4. What is James' opportunity cost of producing chickens?

5. Which person has an absolute advantage in whichactivities?

6.Which person has comparative advantage in potatoes?

7. Which person has comparative advantage in chickens?

8. Suppose that they are thinking of each specializing completelyin the area in which they have a comparative advantage, and then ata rate of 2.5 pounds of potatoes for 1 chicken,would they each bebetter off?
