David and Morgan are farmers. Each one owns an 18-acre plot of land. The following table shows the amount of maize and squash each farmer can produce per year on a given acre. Each farmer chooses whether to devote all acres to producing maize or squash or to produce maize on some of the land and squash on the rest. Maize Squash (Pounds per acre) (Pounds per acre) David 28 7 Morgan 18 6 On the following graph, use the blue line (circle symbol) to plot David's production possibilities frontier (PPF), and use the purple line (diamond symbol) to plot Morgan's PPF. David's PPF Morgan's PPF 0 90 180 270 360 450 540 630 720 810 900 180 162 144 126 108 90 72 54 36 18 0 SQUASH (Pounds) MAIZE (Pounds) 504, 0 Y-Intercept: 0 X-Intercept: None Slope: 0 David has an absolute advantage in the production of maize, andDavid has an absolute advantage in the production of squash. David's opportunity cost of producing 1 pound of squash is pounds of maize, whereas Morgan's opportunity cost of producing 1 pound of squash is pounds of maize. Because David has a opportunity cost of producing squash than Morgan, has a comparative advantage in the production of squash, and has a comparative advantage in the production of maize.
