LERNER INDEX: The difference between price (p) and marginal cost (mc) as a fraction of price, that is [p-mc]/p. The Lerner index is usually taken as an indicator of market power because the larger the index, the larger the difference between price and marginal cost, that is, the larger the distance between the price and the competitive price. The Lerner index depends on the elasticity of demand. The Lerner index is also called the price-cost margin.

DISCOUNT RATE The interest rate charged by the Federal Reserve System (the Fed) for loans to commercial banks, which in principle can be used as a means of a controlling the money supply. An increase in the money supply can be achieved when the Fed lowers the discount rate. A decrease in the money supply can be achieved when the Fed raises the discount rate. The discount rate, which is set by Federal Reserve Banks, subject to approval by the Board of Governors, is used more to signal changes in monetary policy rather than to actually control the money supply. The discount rate is one of the three monetary policy tools that the Fed can use, in principle, to control the money supply. The other two are open market operations and reserve requirements.
