PPC: The abbreviation for production possibilities curve, which is a curve that illustrates the production possibilities for the economy. A production possibilities curve represents the boundary or frontier of the economy's production capabilities. That's why it's also frequently termed a production possibilities frontier (or 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.
