1. Specialization and production possibilities Suppose Bulgaria produces only pressure cookers and air fryers. The resources that are used in the production of these two goods are not specialized- that is, the same set of resources is equally effective at producing both air fryers and pressure cookers. The shape of Bulgaria's production possibilities frontier (PPF) should reflect the fact that as Bulgaria produces more air fryers and fewer pressure cookers, the opportunity cost of producing each additional air fryer The following graphs show two possible PPFs for Bulgaria's decreases t-line PPF (PPF1 ) and a bowed-out PPF (PPF2). increases remains constant Graph 1 Graph 2 PPF , PPF PRESSURE COOKERS PRESSURE COOKERS AIR FRYERS AIR FRYERS
