Introduction to the Production Possibilities Curve (PPC)
As you know, the basic economic problem is scarcity. Since we do not have enough scarce resources to satisfy
everyone's needs and wants, we all have to make choices. We must choose how to spend our time, our energy, our
money, and our material possessions, and for every choice that is made, a cost is suffered.
The relationship between choice and cost can be shown in a graph called a production possibilities curve, or PPC. For
example, consider a student who has 4 hours of free time in the evening. He or she can choose to spend some, all, or
none of those 4 hours studying for a test the following day. He or she could also use the time to catch up on sleep.
These choices can be graphed:
Choice A - spend all 4 hours studying
Choice B- spend 2 hours studying, and 2 hours getting extra sleep
Choice C- spend all 4 hours sleeping
Of course, other combinations of the 4 hours exist.
The student could study for 3.5 hours, and get an extra…

If Carlos spends his entire $160 on milk, he can buy CEREAL (Boxes) Use the blue line (circle symbol) to plot Carlos's budget constraint on the following graph. Next, use the orange point (square symbol) to shade the area that represents combinations of milk and cereal that are affordable for Carlos. Finally, place the black point (plus symbol) on the point on Carlos's budget constraint that corresponds to a scenario in which Carlos spends $80 on each good.
