Choose the correct answer.

A.1 The marginal propensity for consumption shows us:

A. the change in consumption per unit of change in income.

B. the percentage of income consumed.

C. how income changes when consumption changes.

D. all of the above.
A.2 If in a period there is an unpredictable increase in demand, then:

A. the investment made will be equal to the desired investment.

B. the investment made will be greater than the desired investment.

C. the investment made will be less than the desired investment.

D. there will be an unwanted accumulation of stocks of goods.
A.3 In an economy where there is no state and foreign trade, when the marginal momentum for consumption is equal to 0.5, the investment multiplier is equal to:

A. 2. B. 1. C. 0.5. D. 0.

A.4 As a liquidity trap we call the situation where:

A. the interest rate is zero.

B. the interest rate is negative.

C. The demand for money is completely elastic.

D. none of the above.

Expert Solution

Answer 1)A. the change in consumption per unit of change in income is revealed by the marginal propensity to consume.

Answer 2) B. the investment made will be greater than the desired investmentIf in a period there is an unpredictable increase in demand, then: the investment made will be greater than the desired investment.

Answer 3) A. 2

In an economy where there is no state and foreign trade, when the marginal momentum for consumption is equal to 0.5, the investment multiplier is equal to 2

Multiplier= 1/ 1- MPC

Multiplier==1/1- 0.5

Multiplier=1/.5

Multiplier=10/5

Multiplier=2

Answer - A. the interest rate is zero.

As a liquidity trap we call the situation where the interest rate is zero.

2. Assume that the level of autonomous consumption in Mudville is $1000. If the marginal propensity to consume is 0.8, what is the consumption function? Saving function? Give an equation for each and show each graphically. At what level of income is saving = 0? Show on your graphs.

The Giladi family has a linear consumption function with a marginal propensity to consume (MPC) of 0.6, and the Sharoni family has a linear savings function with a marginal propensity to save (MPS) of 0.6. Autonomous consumption (Co) is positive, Thus: a. There is a level of income at which the Giladi family’s consumption equals savings. b. There is a level of income at which the Sharon family’s consumption equals savings. c. It is impossible to determine if in the...

If Sally’s consumption function is linear and her marginal propensity to consume is 0.8, this means that Sally’s total spending cannot exceed 80% of her income. Sally will spend at least 80% of her total income. Sally will not save money regardless of her income. Sally will begin to save at the point where her marginal income is equal to 0.8. (19) If a household’s income increases from $50,000 to $60,000, and as a result, its consumption...
