AE LINE: Another term for aggregate expenditure line, which is a line representing the relation between aggregate expenditures and gross domestic product used in the Keynesian cross. The aggregate expenditure line is obtained by adding investment expenditures, government purchases, and net exports to the consumption line. As such, the slope of the aggregate expenditure line is largely based on the slope of the consumption line (which is the marginal propensity to consume), with adjustments coming from the marginal propensity to invest, the marginal propensity for government purchases, and the marginal propensity to import. The intersection of the aggregate expenditures line and the 45-degree line identifies the equilibrium level of output in the Keynesian cross.

SHORT-RUN PRODUCTION: An analysis of the production decision made by a firm in the short run, with the ultimate goal of explaining the law of supply and the upward-sloping supply curve. The central feature of this short-run analysis is the law of diminishing marginal returns, which results in the short run when larger amounts of a variable input, like labor, are added to a fixed input, like capital. This analysis of short-run production is but the first step in a brisk walk toward a better understanding of supply. Further steps include the cost of short-run production, especially marginal cost, and the market structure in which a firm operates, such as perfect competition or monopoly. See also | fixed input | variable input | law of diminishing marginal returns | marginal product | total product | average product | marginal cost | total variable cost | total cost | total fixed cost | profit maximization | total revenue and total cost | marginal revenue and marginal cost |

DEPOSIT EXPANSION MULTIPLIER The ratio of the change in checkable deposits to the change in reserves, which indicates the magnified change in deposits resulting from a change in reserves. The deposit expansion multiplier indicates how many checkable deposits are created with an injection of additional reserves into the banking system. As the name suggests, the change in checkable deposits is typically a multiple of the initial change in reserves. The size of the deposit expansion multiplier depends on the reserve requirement ratio. The deposit expansion multiplier also forms the core of the money multiplier.
