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.

SAY'S LAW A principle of classical economics developed the French economist Jean-Baptiste Say that is commonly summarized as "supply creates its own demand." This law, also referred to as Say's "theory of markets" or "law of markets," indicates that the act of producing aggregate output generates a sufficient amount of aggregate income to purchase all of the output produced. This principle indicated that excess production or insufficient demand for production was unlikely to occur, at least for any extended period. When combined with flexible prices and saving-investment equality, Say's law further implied that an economy would achieve and maintain full employment of resources. This law was singled out by John Maynard Keynes in his critique of classical economics, but remains relevant in current macroeconomic analysis, reflected in the circular flow model.
