ARC ELASTICITY: The average elasticity for discrete changes in two variables, A and B. The distinguishing characteristic of arc elasticity is that percentage changes are calculated based on the average of the initial and ending values of each variable, rather than only initial values. Arc elasticity is generally calculated using the midpoint formula. Arc elasticity should be compared with point elasticity. For infinitesimally small changes in variables A and B, arc elasticity is the same as point elasticity.

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.
