Ans: c)10
Multiplier = 1/(1-MPC)
where, MPC = Marginal propensity to consume = coefficient of Y in consumption function = 0.9
Therefore, multiplier = 1/(1-0.9)
= 1/0.1
= 10

Suppose that disposable income, consumption, and saving in some country are $800 billion, $700 billion, and $100 billion, respectively. Next, assume that disposable income increases by $80 billion, corisumption rises by $56 blillion, and saving goes up by $24 billion. a. What is the economy's MPC? Instructions: Round your answers to 2 decimal places MPC= What Is its MPS? MPS b. What was the APC before the increase in disposable income? Instructions: Round your answer to 2 decimal places. APC...

Use the table below to determine the MPC and MPS. Disposable Income Consumption Saving $1000 $1100 -$100 2000 1600 400 3000 2100 900 1. Using the above information, what is the MPC and MPS when the DI is 3000? MPC = MPS = 2. What equation could you use to determine the Multiplier, using MPC and MPS? Multiplier = Multiplier = 3. If there is an initial investment spending of $5,000; what would the total change in GDP...

Based off your findings. What is the Multiplier at a disposable income of $2000? 6. If the initial spending is $10,000; what would be the total change in GDP be?
The consumption function is given by the equation: C = 400 + 0.8(Yd) where C = consumption and Yd = disposable income. Currently, the level of disposable income is $5000. What is the current level of consumption? What is the current level of saving? What is the MPC? What is the MPS? Calculate the APC and the APS. 6. We are given the following information about the levels of disposable income and savings: Disposable Income Consumption Savings APC APS MPC...

The MPC is A) the change in consumption divided by the change in income. B) consumption divided by income. C) the change in consumption divided by the change in saving. D) the change in saving divided by the change in income. The MPS is A) the change in saving divided by the change in income. B) 1 + MPC C) income divided by saving. D) total saving divided by total income Saving equals A) Y-C. B) Y - planned 1....
6. Suppose a family's annual disposable income is $8000 of which it saves $2000. (a) What is their APC? (b) If income rises to $10,000 and they plan to save $2800, what are MPS and MPC? (c) Did the family's APC rise or fall with their increase in income? 7. Complete the following table assuming that (a) MPS = 1/5, (b) there is no government and all saving is personal saving.
