Aggregate expected expenditure Depend on income?
Formulas?
Graphs?
MPs?
C-I induced expenditure Consumption C=a+bYD Savings S=-a+(1-b)YD YD:disposable income Y-T a +ve b and m +ve less that 1
AE Does not vary with rGDP
Autonomous expenditure
Planned I G X
Aggregate expenditure schedule
List of level of expenditure planned at each level of rGDP
AE vs rGDP
Actual AE:rGDP
Planned not equal to actual unplanned changes in inventory
Equilibrium expenditure
When planned AE equal rGDP graph meet.
Change in auto E?
Multiplier?
Auto E^ rGDP^ so Induced E^ too
Amt auto E change magnified to determine change in equilibrium expenditure and rGDP
Change in Y/ change auto E
1/(1-slope of AE or MPC) if no import no income tax
Higher slope higher multiplier

On multiplier
Explainnn
Classical
PL not fixed so when auto E AE^ PL ^ hence AE fall back down so multiplier 1
But Keynesian can result in 1.excessive inflation
2.Misallocation if productive resources
Multiplier example
Example: From 1929-33, during the Great Depression, real GDP fell by 6% and unemployment doubled. At the same time, autonomous expenditure fell from £10.7 billion to £10.1 billion, mainly due to a fall in investment.
Aggregate Planned Expenditure?
Planned C + I + G + (X-M)
