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.

RECESSIONARY GAP

The difference between the equilibrium real production achieved in the short-run aggregate market and full-employment real production that occurs when short-run equilibrium real production is less than full-employment real production. A recessionary gap, also termed a contractionary gap, is associated with a business-cycle contraction. This is one of two alternative output gaps that can occur when short-run equilibrium generates production that differs from full employment. The other is an inflationary gap.
