In the aggregate expenditure model, assume that the consumption function is given by C = 800 + 0.58(Y - TP), that planned investment (I) equals 250, and that government purchases (G) and taxes (TP) each equal 200. Assume that there is no import or export spending. If G is now 300, calculate the equilibrium level of income (to 3 decimal places).© BrainMass Inc. brainmass.com October 25, 2018, 8:20 am ad1c9bdddf
As per Aggregate Expenditure Model,
AE = C + I + G +X
AE = Aggregate Expenditure
C = Household Consumption
I = Total Investment
G = Government Expenditure
X = Net Exports (which would be zero in case of Closed Economy as there won't be any Import or Export)
Equilibrium level of Income is said to be one at which AE is equal to Aggregate Income (Y).
Consumption Equation is represented as, C =CA + MPC (Y - TP)
C = Total Consumption
CA = Autonomous Consumption, i.e., amount of consumption ...
Solution contains step by step explanation of calculating equilibrium income through Aggregate Expenditure Model in Closed Economy. It also contains method to find change in equilibrium income as a result of change in value of variables.
Meaning of each component of equation as well as explanation of calculations is provided at appropriated places.
Equilibrium GDP in the Keynesian Model of a Closed Economy
To find equilibrium GDP in the Keynesian model of a closed economy, we add to the C + I schedule:
A) government expenditures on goods and services plus government transfer expenditures.
B) government expenditures on goods and services minus tax receipts.
C) government expenditures on goods and services if financed by new money creation.
D) public expenditures on goods and services plus transfers to the degree financed by new money creation.
E) all government expenditures on goods and services however financed.
