Planned aggregate expenditure

Aggregate expenditure is the current value of all the finished goods and services in the economy. In economics, aggregate expenditure is the current value of all the finished goods and services in the economy. It is the sum of all the expenditures undertaken in the economy by the factors during a specific time period. Written out the equation is: aggregate expenditure equals the sum of the household consumption Cplanned aggregate expenditure, investments Igovernment spending Gand net exports Planned aggregate expenditure.

Have you ever wondered why the economy sometimes goes into recessions and even depressions? If so, you are definitely not alone. Many great economists have thought about this same question. Some of them developed the aggregate expenditures model to help answer this question. In this article, we will explain to you the different components of the aggregate expenditures model as well as its formula.

The expenditure-output model, or Keynesian cross diagram, shows how the level of aggregate expenditure varies with the level of economic output. The equilibrium in the diagram occurs where the aggregate expenditure line crosses the degree line, which represents the set of points where aggregate expenditure in the economy is equal to output, or national income. Equilibrium in a Keynesian cross diagram can happen at potential GDP—or below or above that level. The expenditure-output, or Keynesian Cross, model. From the s until the s, Keynesian economics was usually explained with a different model, known as the expenditure-output approach. This approach is strongly rooted in the fundamental assumptions of Keynesian economics. It focuses on the total amount of spending in the economy, with no explicit mention of aggregate supply or of the price level. Although, it is possible to draw some inferences about aggregate supply and price levels based on the diagram. The axes of the expenditure-output diagram.

The concept of the marginal propensity to consume suggests that consumption contains induced aggregate expenditures; an increase in real GDP raises consumption.

The aggregate expenditure model relates the components of spending consumption, investment, government purchases, and net exports to the level of economic activity. In the short run, taking the price level as fixed, the level of spending predicted by the aggregate expenditure model determines the level of economic activity in an economy. The aggregate expenditure model focuses on the relationships between production GDP and planned spending:. The negative net export link is not large enough to overcome the other positive links, so we conclude that when income increases, so also does planned expenditure. We illustrate this in Figure The equation of the line is as follows:. Figure

Planned aggregate expenditure

The consumption function relates the level of consumption in a period to the level of disposable personal income in that period. In this section, we incorporate other components of aggregate demand: investment, government purchases, and net exports. In doing so, we shall develop a new model of the determination of equilibrium real GDP, the aggregate expenditures model. This model relates aggregate expenditures , which equal the sum of planned levels of consumption, investment, government purchases, and net exports at a given price level, to the level of real GDP. We shall see that people, firms, and government agencies may not always spend what they had planned to spend.

When talking about the expenditure-output model, it is sometimes useful to refer to real GDP as national income. Thus, for a given change in real GDP, consumption rises by a smaller amount. They have to pay taxes, and they can buy imports, both of which reduce the amount of money being multiplied. Computation of the Multiplier The multiplier is the number by which we multiply an initial change in aggregate demand to get the full amount of the shift in the aggregate demand curve. Real Interest Rate Spending on durable goods is likely to be affected when the real interest rate changes. Provided by : Wikipedia. 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. Investment expenditure, government expenditure, and net exports are all set to be exogenous variables in this model, meaning that they do not vary with the current level of real GDP and so must be determined by external forces such as government policy and foreign exchange. From a Keynesian point of view, we could say well you want to just shift this actual curve and there's a bunch of ways in which you can shift the curve. It is mandatory to procure user consent prior to running these cookies on your website. Our independent variable is going to be aggregate income or GDP, however you want to view it, and then our vertical axis is expenditures. In general, the steeper the aggregate expenditures curve, the greater the multiplier. Consumption, investment, government purchases, and net exports are components of aggregate expenditures.

Aggregate expenditure is the current value of all the finished goods and services in the economy. In economics, aggregate expenditure is the current value of all the finished goods and services in the economy. It is the sum of all the expenditures undertaken in the economy by the factors during a specific time period.

Total consumption C is shown in Panel c. Celso Mattheus C. The AD-AS model is used to graph the aggregate expenditure at the point of equilibrium. You have all this inventory building up and so the actual investment would be larger than the planned investment because you have all that inventory built up. When this is occurring an individual store may realize that product is being purchased faster than they are able to order new product in. Once we know the size of the multiplier, we can also calculate the marginal propensity to save MPS and the marginal propensity to consume MPC :. You have said that we can't just increase Y because inventory will build up but if Y is the GDP, increasing G is increasing Y and firms respond by increasing planned expenditure? Aggregate Expenditure Aggregate expenditure is the current value of all the finished goods and services in the economy. Finally, we shall also assume that the only component of aggregate expenditures that may not be at the planned level is investment. In economics, aggregate expenditure is the current value of all the finished goods and services in the economy. Save explanations to your personalised space and access them anytime, anywhere! But a macroeconomy will not always be in equilibrium. Showing how a change in government spending can lead to a new equilibrium. While the measured unemployment rate in labor markets will never be zero, full employment in the labor market occurs when there is no cyclical unemployment. Equilibrium real GDP occurs where the given aggregate expenditures curve intersects the degree line.
