aggregate expenditure curve and consumption function

### CHAPTER 23: EXPENDITURE MULTIPLIER

n if the interest rate falls or expected future disposable income increases, then the consumption function shifts upwards and the implied savings function shifts downwards (see pg 531) Other Components of Aggregate Expenditure (AE):Aggregate expenditure is defined as the value of all of the completed goods and services that currently exist in a country It is determined by calculating the sum of consumption.

### Calculating Aggregate Expenditures

-03-14 Calculating the Aggregate Expenditure Function , sharing included Live TV from 60+ channels No cable box requiredOn 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.

### Aggregate expenditure

In economics, aggregate expenditure (AE) is a measure of national income Aggregate expenditure is defined as the current value of all the finished goods and services in the economy The aggregate expenditure is thus the sum total of all the expenditures undertaken in the economy by the factors during a given time periodDerive an expression for the aggregate expenditure curve and graph it on your exam sheet labeling this initial equilibrium output as point A Also, add this point A to your consumption function Show all work Draw an aggregate demand and an aggregate supply curve in the right hand graph on your exam sheet identifying this initial point as point A NOTE: We are holding the price level fixed at.

27) The short-run aggregate supply (AS) curve shows the relationship between the A)equilibrium national income and desired consumption B)price level and the total output that firms wish to produce and sell, as input prices varyIn a two sector economy, the aggregate demand is a sum of consumption and investment expenditur It is generally agreed that though both consumption and investment functions undergo a change from one period to another, the consumption function is relatively more stable than the investment function Thus, the initial changes in income occur more due to the shifts in the investment function.

### The Aggregate Expenditure Model

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 economyI'll rebuild our planned aggregate expenditure function, but I'll fill in little bit of the details Let's say this is planned, planned aggregate expenditures and this is going to be equal to consumption You'll often see it in a book written like this: Consumption as a function of aggregate.

### Components of Aggregate Demand

Aggregate demand tells the quantity of goods and services demanded in an economy at a given price level In effect, the aggregate demand curve is a just like any other demand curve, but for the sum total of all goods and services in an economy It tells the total amount that all consumers-10-09 This movie goes over aggregate expenditure and its relationship with real GDP and the 45 degree line graph It is important to understand the differences that occur with aggregate expenditure.

### Aggregate Expenditure: Consumption, Investment, Government ,Aggregate expenditure

The Consumption Function - The relationship between the level of income in an economy and the amount s plan to spend on consumption, other things constant s look at their level of disposable income and decide how much to spendIn economics, aggregate expenditure (AE) is a measure of national income Aggregate expenditure is defined as the current value of all the finished goods and services in the economy The aggregate expenditure is thus the sum total of all the expenditures undertaken in the economy by the factors during a given time period.

### Test (a) Questions / Answers

(Figure: Aggregate Expenditures Curve I) (G) Suppose that the consumption function in this economy rises by \$100 The result would be a shift in the: The result would be a shift in the: A) aggregate expenditures curve upward by \$100Aggregate 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.

### Consumption and the Aggregate Expenditures ModelConsumption and the Aggregate Expenditures Model

Learning Objectiv Explain and graph the consumption function and the saving function, explain what the slopes of these curves represent, and explain how the two are related to each otherAggregate expenditures are the sum of planned levels of consumption, investment, government purchases, and net exports at a given price level The aggregate expenditures model relates aggregate expenditures to the level of real GDP We began by observing the close relationship between consumption.

Suppose that the aggregate consumption function is given by the equation C = 200 + 08YD, where C represents consumption and YD represents disposable income (Scenario: Aggregate Consumption Equation) Look at the scenario Aggregate Consumption Equationaggregate demand and expenditure Aggregate demand is a measure the ability to spend or the level of expenditure necessary to command varying quantities of goods and services at different price levels.

### Aggregate expenditure and the 45 degree line (Keynesian ,What causes an aggregate expenditure curve to shift?

Aggregate expenditure and GDP are both function of consumption, investment, government spending, and net exports So the equations for the two are identical: So ,Changes in consumption, investment, government spending, imports, or exports aggregate expenditure = aggregate demand = national income (GDP).

### AmosWEB is Economics: Encyclonomic WEB*pediaAutonomous Expenditure

Because each of these marginals is the slope of the corresponding expenditure line (consumption line, investment line, government purchases line, and net exports line), the slope of the aggregate expenditures line is the summation of the slopes of the lines for each of the four aggregate expenditurAn autonomous expenditure describes the components of an economy's aggregate expenditure that are not impacted by that same economy's real level of income This type of spending is considered.

### Consumption and the Aggregate Expenditures ModelAggregate Expenditure: Investment, Government Spending

Learning Objectiv Explain and graph the consumption function and the saving function, explain what the slopes of these curves represent, and explain how the two are related to each otherLearning Objectiv Explain the investment, government spending, and net export functions; Explain how the aggregate expenditure curve is constructed from the consumption, investment, government spending and net export functions.

### Aggregate Demand Multiplier

In a two sector economy, the aggregate demand is a sum of consumption and investment expenditur It is generally agreed that though both consumption and investment functions undergo a change from one period to another, the consumption function is relatively more stable than the investment function Thus, the initial changes in income occur more due to the shifts in the investment functionIn economics, aggregate expenditure (AE) is a measure of national income Aggregate expenditure is defined as the current value of all the finished goods and services in the economy The aggregate expenditure is thus the sum total of all the expenditures undertaken in the economy by the factors during a given time period.
