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.

TAX MULTIPLIER

A measure of the change in aggregate production caused by changes in government taxes. The tax multiplier is the negative marginal propensity to consume times one minus the slope of the aggregate expenditures line. The simple tax multiplier includes ONLY induced consumption. More complex tax multipliers include other induced components. Two related multipliers are the expenditures multiplier, which measures the change in aggregate production caused by changes in an autonomous aggregate expenditure, and the balanced-budget multiplier which measures the change in aggregate production from equal changes in both taxes and government purchases.

[What's This?]

Today, you are likely to spend a great deal of time browsing about a thrift store hoping to buy either a 50 foot extension cord or a combination CD player, clock radio, and telephone (with answering machine). Be on the lookout for empty parking spaces that appear to be near the entrance to a store.
