Suppose that the community of Markstown produces two goods: Michelob light beer (MLB) and bacon/lettuce/tomato sandwiches (BLTs). Assuming increasing opportunity costs, draw a production possibilities curve (PPC) for Markstown (be sure to label both axes correctly). On your graph of the PPC from #1, find and label the following: an inefficient point (label it X) an efficient point (label this one Y) an unattainable point (label it Z) a. b. C. Due to an increase in immigration across its borders, Markstown has experienced an increase in the size of its labor force. On your graph above, show how this change affects the PPC of Markstown.
