LRMC CURVE: The common abbreviation for the long-run marginal cost curve, which is the graphical representation of the relationship between long-run marginal cost and the quantity of output produced. Like other marginal curves, the long-run marginal cost curve follows the average-marginal rule relative to the long-run average cost curve. In all outward appearance, the long-run marginal cost curve looks very much like the short-run marginal cost, that is, it is U-shaped. However, the U-shape is attributable to returns to scale rather than increasing and decreasing marginal returns.

ARC ELASTICITY

The average elasticity for discrete changes in two variables. The distinguishing characteristic of arc elasticity is that percentage changes are calculated based on the average of initial and ending values of each variable, rather than initial values. Arc elasticity is generally calculated using the midpoint elasticity formula. The contrast to arc elasticity is point elasticity. For infinitesimally small changes in two variables, arc elasticity is the same as point elasticity.
