and a decrease in the interest rate causes
an increase in the amount of real planned investment
Dissaving occurs
at income levels less than $40 billion. https://i.imgur.com/39JfwOz.png
The value for the multiplier is given to be 14 Calculate both the MPS and the MPC.
mps = .07 mpc = .93
If real GDP falls below total planned expenditures the economy will see
production and employment increases .
Planned real investment is determined by the
rate (of interest)
When disposable income increases from $0 to $40 billion
saving increases by $0.10 for each additional dollar of disposable income. https://i.imgur.com/39JfwOz.png
Current disposable income held to buy consumption goods in the future is referred to as
saving.
Average Propensity to Save (APS)
saving/income
Suppose that when disposable income increases by $1,000, consumption spending increases by $750. Given this information, we know that the marginal propensity to consume (MPC) is
0.75.
In a simple economy (assume there are no taxes, thus Y is disposable income), the consumption function is: Upper C equals 200 plus 0.8 Upper Y In this economy, the level of income at which the consumer breaks even (consumption equals income) is
1000. https://i.imgur.com/nLJj6Oe.png
Which of the following statements is true?
At an income level of $0 billion there is dissaving equal to $30 billion.
Which of the following statements best reflects the relationship between saving and savings?
Saving is a flow variable; savings is a stock variable.
If the interest rate increases, which of the following will occur?
The quantity of planned investment will decrease.
Suppose that planned savings is less than planned investment at the current level of real GDP. Which of the following will occur?
There will be an unplanned decrease in business inventories, and in the next period, real GDP will increase .
At equilibrium in this economy, what is the relationship between planned savings and planned investment?
They are equal.
All of the following will cause the planned investment function to shift leftward except
an increase in the interest rate.
MPC (marginal propensity to consume)
change in consumption/change in income
MPS (marginal propensity to save)
change in savings/change in income
average propensity to consume
consumption/income
Saving is the portion of
disposable income that is not consumed
In the Keynesian model equilibrium national income
equals planned consumption, investment, government, and net export expenditures.
Consumption is a
flow variable
Consumption goods are
goods purchased by households for immediate use
In the Keynesian model, if disposable income were to increase households would
increase both their consumption and saving
The amount of planned real investment in the economy has ________ relationship with the rate of interest.
inverse
The relationship between the MPC and the MPS indicates that the entire increase in household disposable income
is distributed between consumption and saving.
Investment is
spending by businesses on things which can be used to produce goods and services in the future.
If autonomous consumption should increase then
the consumption function shifts upward.
