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.

KEYNESIAN ECONOMICS A theory of macroeconomics developed by John Maynard Keynes based on the proposition that aggregate demand is the primary source of business-cycle instability and the most important cause of recessions. Keynesian economics points to discretionary government policies, especially fiscal policy, as the primary means of stabilizing business cycles and tends to be favored by those on the liberal end of the political spectrum. The basic principles of Keynesian economics were developed by Keynes in his book, The General Theory of Employment, Interest and Money, published in 1936. This work launched the modern study of macroeconomics and served as a guide for both macroeconomic theory and macroeconomic policies for four decades. Although it fell out of favor in the 1980s, Keynesian principles remain important to modern macroeconomic theories, especially aggregate market (AS-AD) analysis.
