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.

REAL-BALANCE EFFECT A change in aggregate expenditures on real production made by the household, business, government, and foreign sectors that results because a change in the price level alters the purchasing power of money. This is one of three effects underlying the negative slope of the aggregate demand curve associated with a movement along the aggregate demand curve and a change in aggregate expenditures. The other two are interest-rate effect and net-export effect. The real-balance effect is somewhat analogous to the income effect underlying the negative slope of the market demand curve.
