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.

LONG-RUN AGGREGATE SUPPLY The total (or aggregate) real production of final goods and services available in the domestic economy at a range of price levels, during a period of time in which all prices, especially wages, are flexible, and have achieved their equilibrium levels. Long-run aggregate supply, commonly abbreviated LRAS, is one of two aggregate supply alternatives, distinguished by the degree of price flexibility. The other is short-run aggregate supply. Long-run aggregate supply is combined with aggregate demand, and often short-run aggregate supply, in the long-run aggregate market (or AS-AD) analysis used to analyze economic growth, business-cycle instability, unemployment, inflation, government stabilization policies, and related macroeconomic topics.

[What's This?]
Today, you are likely to spend a great deal of time at the confiscated property police auction trying to buy either a coffee cup commemorating the 1960 Presidential election or a how-to book on fixing your computer, with illustrations. Be on the lookout for strangers with large satchels of used undergarments.
