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.

PRICE LEVEL The average of the prices of goods and services produced in the aggregate economy. In a theoretical sense, the price level is the price of aggregate production. In a practical sense, the price level is commonly measured by either of two price indexes, the Consumer Price Index (CPI) or the GDP price deflator. The CPI is the price index widely publicized in the media and used by the general public. The GDP price deflator, in contrast, is less well-known, but is usually the price index of choice among economists. The inflation rate is calculated as the percentage change in the price level.
