Part II: Make sure you read and do ALL parts of each question. Show as much work as possible. TRY to get started on every question. Show us something. Write legibly and remember to label all graphs and axes in diagrams.
1. Suppose the supply and demand curves for milk in Cortland are described by the following equations (where Q is measured in gallons and P is price per gallon):
Demand: QD = 18 - P Supply: QS = -6.0 + 5P
a. Graph the demand and supply curves as we have set it up in class (remember to label everything in your graph including endpoints of demand and supply).
b. Determine the proper equation for the demand curve as it is illustrated on your graph.
c. Determine the proper equation for the supply curve as it is illustrated on your graph.
d. Determine the equilibrium price and quantity values and label them on your graph.

2. Abe and Betty are the only producers/consumers in a small (American) football loving economy. Abe and Betty produce and consume only two things: NFL (National Football League) logo T-shirts and logo pins.
Given 60 hours of work in a week, Abe can produce a maximum of 4 T-shirts or 12 pins, or any combination along a straight line PPF between the two.
Given 60 hours of work in a week, Betty can produce a maximum of 5 T-shirts or 20 pins, or any combination along a straight line PPF between the two.
Hours Required for One Unit of OutputPerson / T-shirts / Pins
Abe / ______hours / ______hours
Betty / ______hours / ______hours
a. Fill in the missing numbers in the table.
b. Who has the absolute advantage in T-shirt production? Who has the comparative advantage in T-shirt production?
c. Assume that Abe and Betty have not taken Econ 1120, and hence don’t know the wonders of trade. That is, they insist on self-producing everything they consume. If Abe wants to consume 2 T-shirts, how many pins, at most, can Abe have per week? If Betty wants to consume 16 pins, how many T-shirts, at most, can she consume per week? When Abe and Betty do this, what is the total number of pins and total number of T-shirts made summing over the two of them?
d. Assume Abe and Betty take Econ 1120 and see the light and realize they should be efficient. Putting PINS ON THE HORIZONTAL and T-SHIRTS ON THE VERTICAL, illustrate the efficient combined production possibility frontier. For full credit, if there are any kink points in your graph, label the number of units of each task at any/all kink points. Also label the endpoints of the PPF.
e. If Abe and Betty specialize and trade with each other, what would be the bounds of an “international” exchange rate between T-shirts and Pins between Abe and Betty? For full credit you must give a brief explanation of why.
