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.

In fact, given that it refers to the sum total of the economy's resources and productive activity, economic pie is filled to the brim with sustenance. Unfortunately, Scarcity Stan and the congregation of people we call society, has only one economic pie, and while it's pretty large, it's never quite as big as we would like.
