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.

SCARCE RESOURCE

A resource with an available quantity less than its desired use. Scarce, or economic, resources are also called factors of production and are generally classified as either labor, capital, land, or entrepreneurship. Scarce resources are the workers, equipment, raw materials, and organizers used to produce scarce goods. Like the more general society-wide condition of scarcity, a given resource falls into the scarce category because it has a limited availability in combination with greater (potentially unlimited) productive uses.
