LAW OF INCREASING OPPORTUNITY COST: The proposition that opportunity cost, the value of foregone production, increases as more of a good is produced. This "law" can be seen in the production possibilities schedule and is illustrated graphically through the slope of the production possibilities curve. It generates the distinctive convex shape of the curve, making it flat at the top and steep at the bottom.

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.
