GOVERNMENT INTERVENTION: Actions on the part of government that affect economic activity, resource allocation, and especially the voluntary decisions made through normal market exchanges. Government, by its very nature, is designed to intervene in voluntary market activity. Some of the more common types of government intervention includes taxes, price controls, assorted regulations, and control over government spending. The general justification for government intervention is that voluntary decisions by consumers and businesses fail to achieve efficiency or other goals deemed important by society.

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.
