The Aggregate Expenditure Model The aggregate expenditure (or income-expenditure) model is a macroeconomic model that focuses on the relationship between total spending and real GDP, assuming the price level is constant. To fully investigate this model we first need to define the aggregate expenditure function. Aggregate expenditure
The aggregate expenditures curves for price levels of 1.0 and 1.5 are the same as in Figure 28.13 "From Aggregate Expenditures to Aggregate Demand", as is the aggregate demand curve. Now suppose a $1,000-billion increase in net exports shifts each of the aggregate expenditures curves up; AE P=1.0, for example, rises to AE ′ P=1.0 .
In the graph below, we show the standard aggregate expenditures curve at three different price levels. When prices are high (P1), Consumption is low; as prices fall to P2 and P3, Consumption rises. As the Consumption function shifts upward due to the falling prices, the …
The characteristics of consumption functions are important for many questions in both macroeconomics and microeconomics. In macroeconomic models the consumption function tracks total aggregate consumption expenditures; for simplicity it is assumed to depend on a basic subset of the factors economists believe are important at the level.
Macroeconomics IS Curve IS Curve Think of the national income and product y and the interest rate r as defining the state of the economy. Given these two variables, one can determine the aggregate demand. In figure 2, the IS curve shows the combinations of y and r such that aggregate demand equals national product. 6

The aggregate expenditures curves for price levels of 1.0 and 1.5 are the same as in Figure 13.16 "From Aggregate Expenditures to Aggregate Demand", as is the aggregate demand curve. Now suppose a $1,000-billion increase in net exports shifts each of the aggregate expenditures curves up; AE P=1.0, for example, rises to AE ′ P=1.0 .
The consumption function becomes flatter. 2. Saving in our simple model. 3. The difference between consumption spending and disposable income. 4. If income increases by $100 and the MPS is 1/4, then the amount saved equals. 5. A that expects a decrease in disposable income in the future will.
Consumption Function: The consumption function, or Keynesian consumption function, is an economic formula representing the functional relationship …
the level of aggregate expenditure that occurs when aggregate planned expenditure equals real GDP multiplier the amount by which a change in any component of autonomous expenditure is magnified or multiplied to determine the change in equilibrium expenditure and real GDP that it generates.
(A) aggregate demand curve to shift leftward. (B) production possibilities curve to shift in. (C) Phillips curve to shift out. (D) long-run aggregate supply curve to shift rightward. (E) consumption function to shift down. 6. Which of the following is a fiscal policy that would increase aggregate demand in the Keyne-sian model? (A) A decrease ...
autonomous consumption will A) shift the aggregate expenditure function downward. B) change the slope of the consumption function. C) shift the consumption function upward. D) decrease the marginal propensity to save.

Graphically, the aggregate expenditure function is formed by adding together (or stacking on top of each other) the consumption function (after taxes), the investment function, the government spending function, and the net export function. In its most basic form, the graph of aggregate expenditures looks like the graph shown in Figure 5.
The 45 degree line (also known as the Keynesian Cross) is a tool used by economists to show how differences in aggregate expenditures and real GDP can affect business inventories which will affect future levels of real GDP. Aggregate expenditure and GDP are both function of consumption, investment, government spending, and net exports.
The Aggregate Expenditure Model We'll define Aggregate Expenditure (AE) as the sum of expenditures on all final goods and services at a given price level. ... First, the mpc is the slope of the consumption function (equation) and the slope of the AE equation. This is true because we have assumed that so many of our expenditure categories are ...
A) shifts the aggregate expenditure curve upward and increases the quantity of real GDP demanded. B) shifts the aggregate demand curve rightward and increases equilibrium GDP. C) decreases aggregate planned expenditures and shifts the aggregate demand curve leftward. D) shifts both the aggregate expenditures curve and aggregate demand curve upward.
Thus, the intercept of the aggregate expenditures curve in Panel (b) is the sum of the four autonomous aggregate expenditures components: consumption (C a), planned investment (I P), government purchases (G), and net exports (X n). In Panel (a), the intercept includes only the first two components.
The level of aggregate expenditure and real GDP at which spending plans are fulfilled. Aggregate planned expenditure (AE) equals to aggregate expenditure （real GDP）.,GDP == AE . Consumption function AE 45° line 。 Unplanned inventory investment unplanned inventory change 0 。
Therefore, in actual practice the curve depicting the consumption function will deviate from the 45° line. If we represent the above consumption schedule by a curve, we would get the propensity to consume curve such as CC in Fig. 6.1. It is evident from this figure that the consumption function curve CC' deviates from the 45° line OZ.
On the aggregate expenditure model, equilibrium is the point where the aggregate supply and aggregate expenditure curve intersect. An increase in the expenditure by consumption (C) or investment (I) causes the aggregate expenditure to rise which pushes the …
An aggregate expenditures curve assumes a fixed price level. If the price level were to change, the levels of consumption, investment, and net exports would all change, producing a new aggregate expenditures curve and a new equilibrium solution in the aggregate expenditures model. A change in the price level changes people's real wealth.
Aggregate expenditure (AE) is the sum of consumption, investment, government purchases, and net export. Of these four sectors, the consumption represents the largest share. The consumption function: C = Co + MPC (Yd) C = total consumption. Co = autonomous consumption whose amount is independent of disposable income
The aggregate expenditure (AE) curve is drawn on the basis of given a given constant price level. Changes in price level cause shifts in AE curve. A rise in prices of goods and services causes a downward shift in the AE curve while a fall in price leads to upwards shift of the curve. AE 0 is the original aggregate expenditure curve based on ...
The Investment Multiplier. The model of Aggregate Expenditures that we are currently considering is often called a Keynesian Model because it was first formulated by British economist John Maynard Keynes in his General Theory of Employment, Interest, and Money, published in 1936—at the height of the great depression. One of the central premises of Keynesian economics is the idea of a multiplier.
Aggregate Expenditures Curves and Price Levels. An aggregate expenditures curve assumes a fixed price level. If the price level were to change, the levels of consumption, investment, and net exports would all change, producing a new aggregate expenditures curve and a new equilibrium solution in the aggregate expenditures model.
The study examined the determinants of aggregate consumption expenditure in Nigerian. The model used in the study was derived from the Keynesian consumption function where consumption is explained by variations in income, C= f(Y). It was also specified to embrace the postulates of consumption expenditure that are not based
Thus, the intercept of the aggregate expenditures curve in Panel (b) is the sum of the four autonomous aggregate expenditures components: consumption (C a), planned investment (I P), government purchases (G), and net exports (X n). In Panel (a), the intercept includes only the first two components.
The aggregate demand function is obtained by a vertical summation of the investment function and consumption function. In the Keynesian theory, there are two approaches to the determination of income and output: Aggregate Demand ‒ Aggregate Supply Approach and Saving ‒ Investment Approach .
A. Graphical Representation of the Expenditure Function: The consumption and investment functions given in Table 32.4 are illustrated in Fig. 32.10. On the basis of these two functions we derive the aggregate expenditure function. In fact, the aggregate expenditure (C + I) function is the vertical summation of the individual expenditure ...
