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.

TWO-SECTOR AGGREGATE EXPENDITURES LINE A graphical depiction of the relation between aggregate expenditures by the two private sectors (household and business) and the level of aggregate income or production. The two-sector aggregate expenditures line combines consumption expenditures and investment expenditures. The slope of this aggregate expenditures line is based on the marginal propensity to consume, adjusted for the marginal propensity to invest if it is assumed to be induced when constructing the line. This is one of three aggregate expenditures lines based on the number of sectors included. The others are the three-sector aggregate expenditures line and the four-sector aggregate expenditures line.
