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.

MARGINAL UTILITY The additional utility obtained from the consumption or use of an additional unit of a good. It is specified as the change in total utility divided by the change in quantity. Marginal utility indicates what each additional unit of a good is worth to a consumer and provides a theoretical basis for understanding market demand and the law of demand. Marginal utility generally declines with increased consumption of a good, a reflection of the law of diminishing marginal utility.
