On the following graph, use the blue line (circle symbol) to plot Bob's production possibilities frontier (PPF), and use the purple line (diamond symbol) to plot Cho's PPF. 200 O 180 Bob's PPF 160 140 CORN (Bushels) 120 Cho's PPF 100 80 GO 40 20 O 0 100 200 300 400 500 600 7 700 800 900 1000 RYE (Bushels)1. Specialization and production possibilities Suppose Bulgaria produces only tablets and smartphones. The resources that are used in the production of these two goods are not specialized-that is, the same set of resources is equally useful in producing both smartphones and tablets. The shape of Bulgaria's production possibilities frontier (PPF) should reflect the fact that as Bulgaria produces more smartphones and fewer tablets, the opportunity cost of producing each additional smartphone The following graphs show two possible PPFs for Bulgaria's eco decreases e PPF (PPF: ) and a bowed-out PPF (PPF2). increases remains constant\f2. Comparative and absolute advantage Bob and Cho are farmers. Each one owns a 20-acre plot of land. The following table shows the amount of rye and corn each farmer can produce per year on a given acre. Each farmer chooses whether to devote all acres to producing rye or corn or to produce rye on some of the land and corn on the rest. Rye Corn (Bushels per acre) (Bushels per acre) Bob 20 Cho 28 On the following graph, use the blue line (circle symbol) to plot Bob's production possibilities frontier (PPF), and use the purple line (diamond symbol) to plot Cho's PPF.
