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.

POLICY LAGS

Time lags that occur between the onset of an economic problem and the full impact of the policy intended to correct the problem. Policy lags come in two broad categories--inside lag (getting the policy activated) and outside lag (the subsequent impact of the policy). The three specific inside lags are recognition lag, decision lag, and implementation lag. The one specific outside lag is termed impact lag. Policy lags can reduce the effectiveness of business-cycle stabilization policies and can even destabilize the economy. Policy lags, especially inside lags, are often different for monetary policy than for fiscal policy.
