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.

BUSINESS CYCLE INDICATORS

Assorted economic statistics that provide valuable information about the expansions and contractions of business cycles. These statistics are grouped into three sets--lagging, coincident, and leading. Leading economic indicators tend to move up or down a few months BEFORE business-cycle expansions and contractions. Coincident economic indicators tend to reach their peaks and troughs AT THE SAME TIME as business cycles. Lagging economic indicators tend to rise or fall a few months AFTER business-cycle expansions and contractions.

Today, you are likely to spend a great deal of time searching for rummage sales looking to buy either a coffee cup commemorating last Friday (you know why) or a wall poster commemorating the first day of spring. Be on the lookout for strangers with large satchels of used undergarments.
