U-SHAPED COST CURVES: The family of short-run cost curves consisting of average total cost, average variable cost, and marginal cost, all of which have U-shapes. They are U-shaped because each has high but falling cost at low quantities of output, which then reaches a minimum, then has rising cost at larger quantities of output. Although the average fixed cost curve is not U-shaped, it's occasionally included with the other three just for sake of completeness.

MONETARY BASE

The combination of currency held by the nonbank public, vault cash held by banks, and Federal Reserve deposits of the banks. Also termed high-powered money, these are the three monetary components over which the Federal Reserve System has relatively complete control. Due to this control, the monetary base is often used as a guide for monetary policy. The monetary base differs from a relative monetary aggregate, M1, through the inclusion of vault cash and Federal Reserve deposits and the exclusion of checkable deposits.
