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.

CONSUMPTION FUNCTION A mathematical relation between consumption and income by the household sector. The consumption function can be stated as an equation, usually a simple linear equation, or as a diagram designated as the consumption line. This function captures the consumption-income relation that forms one of the key building blocks for Keynesian economics. The two key parameters of the consumption function are the intercept term, which indicates autonomous consumption, and the slope, which is the marginal propensity to consume and indicates induced consumption. Aggregate expenditures used in Keynesian economics are derived by adding investment, government purchases, and net exports to the consumption function.
