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.

FEDERAL RESERVE BRANCH BANKS

A collection of 25 government banking institutions that are part of the U.S. Federal Reserve System and which support the activities of the 12 Federal Reserve District Banks that supervise, regulate, and interact with commercial banks as they carry out the policies established by the Federal Reserve Board of Governors. Federal Reserve Banks, both District and Branch, are often termed bankers' banks in that they provide banking services to commercial banks. The 37 separate banks--12 District Banks and 25 Branch Banks--spread across the country are what help make the Federal Reserve System a decentralized central bank.
