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.

PERFECT COMPETITION, LONG-RUN ADJUSTMENT

A perfectly competitive industry undertakes a two-part adjustment to equilibrium in the long run. One is the adjustment of each perfectly competitive firm to the appropriate factory size that maximizes long-run profit. The other is the entry of firms into the industry or exit of firms out of the industry, to eliminate economic profit or economic loss. The end result of this long-run adjustment is a multi-faceted equilibrium condition that price is equal to marginal cost and average cost (both short run and long run).

[What's This?]

Today, you are likely to spend a great deal of time waiting for visits from door-to-door solicitors trying to buy either a computer that can play music and burn CDs or a T-shirt commemorating last Friday (you know why). Be on the lookout for fairy dust that tastes like salt.
