PRODUCTION POSSIBILITIES CURVE A curve that illustrates the production possibilities of an economy--the alternative combinations of two goods that an economy can produce with given resources and technology. A production possibilities curve (PPC) represents the boundary or frontier of the economy's production capabilities, hence it is also frequently termed a production possibilities frontier (PPF). As a frontier, it is the maximum production possible given existing (fixed) resources and technology. Producing on the curve means resources are fully employed, while producing inside the curve means resources are unemployed. The law of increasing opportunity cost is what gives the curve its distinctive convex shape.
