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.

LONG-RUN TOTAL COST The opportunity cost incurred by all of the factors of production used in the long run (when all inputs are variable) by a firm to produce a good or service, including wages paid to labor, rent paid for the land, interest paid to capital owners, and a normal profit earned by entrepreneurs. Unlike short-run total cost, long-run total cost cannot be separated into fixed cost and variable cost. In the long run, all inputs are variable, so all cost is variable.
