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.

KINKED-DEMAND CURVE ANALYSIS

An analysis using the kinked-demand curve to explain rigid prices often found with oligopoly. The kinked-demand curve contains two distinct segments--one for higher prices that is more elastic and one for lower prices that is less elastic. Key to this analysis is that the corresponding marginal revenue curve contains three segments--one associated with the more elastic segment, one associated with the less elastic segment, and one associated with the kink. A profit-maximizing firm can then equate marginal cost to a wide range of marginal revenue values along the vertical segment of the marginal revenue curve. This suggests that marginal cost must change significantly before an oligopolistic firm is inclined to change price.
