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.

BALANCE ON SERVICES

A subset of the balance of payments current account that records the difference between the payments received for exports of services to other nations and the payments made for the imports of services from other nations. The flow of payments is for intangible services, not for physical or tangible goods. The balance on services is thus appropriately divided into services exported and services imported. Two other subsets of the current account include the balance on merchandise trade and unilateral transfers. The commonly termed balance of trade is the sum of the balance on merchandise trade and the balance on services.
