Each farmer chooses whether to devote all acres to producing maize or squash or to produce malze on seme of the land and squash on the rest. On the following graph, use the blue line (circle symbol) to plot David's production possibilities frontier (PPF), and use the purple fine (diamond symbol) to plot Morgan's PPF. has an absolute advantage in the production of maire, and has an absolute advantage in the production of squash. David's opportunity cost of producing 1 peund of squash is squash is pounds of maize. Because David has a comparative advantage in the production of squash, and pounds of malze, whereas Morgan's opportunity cost of producing 1 pound of opportunity cost of producing squash than Morgan, has a has a comparative advartage in the production of maise
