The aggregate expenditure model relates aggregate expenditures, which is the sum of planned level of consumption + investment + government purchases + net exports at a given price level, to the level of GDP. The key word here is planned.
GDP is the same as aggregate expenditures(AE) except for one difference.
People, firms and governments don't always spend what they had planned.
So AE differs from GDP in that it deals exclusively with amounts firms intend to invest, and not necessarily taking into account amounts that will actually be invested as in GDP
Where GDP is defined as C + I + G + NX and I = Ip + Iu
(planned + unplanned investment), Aggregate Expenditures is defined as
C + Ip + G + NX.
AE (Aggregate Expenditure) is used in conjunction with GDP in the Aggregate Expenditures Model to predict future GDP direction. In this model, when AE = GDP then the economy is in equilibrium. According to this model an economy will move towards its equilibrium causing changes in the GDP.

What does investment affect in the keynesian model?
Government expenditure.

What is the output expenditure model?
The output expenditure model, also known as the Keynesian expenditure approach, focuses on the total spending in an economy as the primary driver of economic activity. It posits that aggregate demand, consisting of consumption, investment, government spending, and net exports, determines overall output and employment levels. This model emphasizes the importance of fiscal policy and consumer confidence in influencing economic performance. By analyzing how different components of expenditure interact, policymakers can better understand and manage economic fluctuations.
What is IS-LM model?
It is a diagrammatic representation of a model of aggregate demand determination based upon the locus ofequilibrium points in the aggregate expenditure sector (IS) and the monetary sector(LM).
Derive aggregate demand curve from aggregate expenditure model?
an increase in price level would lead to a fall in AE, vice versa. So by plotting those points out, you can derive an AD curve

What is an expenditure multiplier model?
The model tells you how much you need to multiply an initial autonomous change in AD (aggregate demand) to determine the total change in AD.

Difference between keynesian model and AD-AS model?
Keynesian model is able to show how leakages and injections can influence the economy. AD-AS model is able to show changes in prices (inflation).
What are the four sectors in Keynesian macroeconomic model?
The four sectors in Keynesian macroeconomic model are business, household, foreign sector and government. The Keynesian macroeconomics focuses on a broad scale where the above mentioned sectors play an important role.
What is the major difference between the classical model and the Keynesian model?
The major difference between the classical model and the Keynesian model is their approach to government intervention in the economy. The classical model believes in a hands-off approach, where the economy will naturally correct itself, while the Keynesian model advocates for government intervention to stimulate economic growth and stabilize fluctuations.
The quantity of full employment in the aggregate supply aggregate demand model is similar to the conditions in which other model?
The quantity of full employment in the aggregate supply aggregate demand model is similar to the conditions in which other model. (Market Supply and Demand.)
The output-Expenditure Model was made famous by?
The output-expenditure model was made famous by economist John Maynard Keynes, particularly through his work in "The General Theory of Employment, Interest, and Money" published in 1936. This model emphasizes the relationship between total output (or income) in an economy and the total expenditure, highlighting the role of aggregate demand in determining economic activity. It laid the foundation for modern macroeconomic theory and policy, particularly in the context of managing economic fluctuations.
What is the price level assumed to be in the simple Keynesian model of determination of income?
exogenous and constant
