AGGREGATE EXPENDITURE EQUATION: An equation indicating that aggregate expenditures (AE) are the sum of consumption expenditures (C), investment expenditures (I), government purchases (G), and net exports (X-M), stated as: AE = C + I + G + (X-M). This equation surfaces in the Keynesian economic income-expenditure model in the form of the aggregate expenditures line. However, it's also central throughout the study of macroeconomics, including aggregate demand and the measurement of gross domestic product.

KINKED-DEMAND CURVE ANALYSIS An analysis using the kinked-demand curve to explain rigid prices often found with oligopoly. The kinked-demand curve contains two distinct segments--one for higher prices that is more elastic and one for lower prices that is less elastic. Key to this analysis is that the corresponding marginal revenue curve contains three segments--one associated with the more elastic segment, one associated with the less elastic segment, and one associated with the kink. A profit-maximizing firm can then equate marginal cost to a wide range of marginal revenue values along the vertical segment of the marginal revenue curve. This suggests that marginal cost must change significantly before an oligopolistic firm is inclined to change price.
