RESERVE REQUIREMENTS: Rules by the Federal Reserve System governing the amount of bank reserves that banks must keep to back up their deposits. Legal reserve requirements came about because banks that practice fractional-reserve banking are sometimes inclined to make too many interest-paying loans and neglect to keep enough reserves on hand to pay their depositors. In principle, the Fed can alter reserve requirements to control the money supply. In practice, however, the Fed prefers to use open market operations or the discount rate.

KINKED-DEMAND CURVE ANALYSIS

An analysis using the kinked-demand curve to explain rigid prices often found with oligopoly. The kinked-demand curve contains two distinct segments--one for higher prices that is more elastic and one for lower prices that is less elastic. Key to this analysis is that the corresponding marginal revenue curve contains three segments--one associated with the more elastic segment, one associated with the less elastic segment, and one associated with the kink. A profit-maximizing firm can then equate marginal cost to a wide range of marginal revenue values along the vertical segment of the marginal revenue curve. This suggests that marginal cost must change significantly before an oligopolistic firm is inclined to change price.

Be on the lookout for fairy dust that tastes like salt.

"Everyone's got it in him, if he'll only make up his mind and stick at it. None of us is born with a stop-valve on his powers or with a set limit to his capacities. There's no limit possible to the expansion of each one of us."
