MARGINAL COST: The change in total cost (or total variable cost) resulting from a change in the quantity of output produced by a firm in the short run. Marginal cost indicates how much total cost changes for a give change in the quantity of output. Because changes in total cost are matched by changes in total variable cost in the short run (remember total fixed cost is fixed), marginal cost is the change in either total cost or total variable cost. Marginal cost, usually abbreviated MC, is found by dividing the change in total cost (or total variable cost) by the change in output.

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.
