AGGREGATE EXPENDITURES LINE: 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, MICROECONOMICS In terms of the microeconomic analysis of production and supply, a period of time in which at least one input under the control of a firm used in the production process is variable and at least one input is fixed. In the short run, the variable input is usually labor and the fixed input is capital. The short-run analysis of production reveals the law of diminishing marginal returns and provides an understanding of the upward-sloping supply curve and the law of supply. This is one of four production time periods used in the study of microeconomics. The other three are long run, very long run, and very short run (or market period). The short run is also a time period designation used in the macroeconomic analysis of business cycles.
