Q

Marginal propensity to consume (MPC)

A

The increase in consumer spending when disposable income rises by $1

∆ Consumer spending

∆ Disposable income

*usually between 0-1 because consumers dont spend all of an additional dollar

Q

Principal factors of investment spending

A

interest rate

expected future level of real GDP

current level of production capacity

17
Q

Planned investment spending

A

the investment spending businesses plan to undertake during a given period

18
Q

Interest rates have biggest effect on what kind of investment spending?

A

residential construction

19
Q

higher interest rate leads to

A

lower level of planned investment spending

20
Q

Retained earnings

A

Past profits used to finance investment spending

21
Q

The higher the current capacity

A

the lower the investment spending

22
Q

investment spending slumps

A

periods of low investment spending

23
Q

accelerator principle

A

A higher growth rate of real GDP leads to higher planned investment spending but a lower growth rate of GDP leads to lower planned investment spending

24
Q

Inventories

A

Stocks of goods held to satisfy future sales

25
Inventory investment
the value of the change in total inventories held in the economoy during a given period
26
Unplanned inventory investment
Occurs when actual sales are more or less than businesses expected, leading to unplanned changes in inventories
27
Actual investment spending
The sum of planned investment spending and unplanned inventory investment Unplanned investment + Planned investment
28
positive unplanned investment
sales are less than had been forecast
29
negative unplanned investment
Sales are greater than forecast
30
Housing bubble
People were buying housing based on unrealistic expectations about future price increases
31
inventory overhang
A high level of unplanned inventory investment throughout the economy
32
Planned aggregate spending
The total amount of planned spending in the economy = Consumption + Planned Investment
33
GDP =
GDP = AEplanned + Iunplanned
34
income expenditure equilibrium
When aggregate output, measured by real GDP, is equal to planned aggregate spending
35
Income-expenditure equilibrium GDP
The level of real GDP at which real GDP equals planned aggregate spending Y\*
36
Keynsian cross
a diagram that identifies income-expenditure equilibrium as the point where the planned aggregate spending line crosses the 45 degree line
37
Leading indicator of future economic activity
changes in inventories
38
∆Y\* =
∆Y\* = Multiplier x ∆AAEplanned
