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.

FIRM

An organization that combines scarce resources for the production and supply of goods and services. The firm is used by entrepreneurs to bring together otherwise idle resources. The term firm is often used synonymously with the business, enterprise, or company. If there is a difference, a firm is functionally defined and need not be a typical for-profit business. A firm can be profit oriented, nonprofit, privately owned, or government controlled.
