C Correct answer
Explanation

APC refers to Average Propensity to Consume which defines the amount of consumption in every 1 rupee of income for all level of income which can never be negative because consumption is never negative owing to the very existence of life and basic needs to satisfy it.

D Correct answer
Explanation

APS refers to Average Propensity to save which defines the amount of savings in every 1 rupee of income for all level of income which can never be more than one as savings can be negative in situations when consumption is more than the national income leading to dis-savings in the economy i.e. before the break even point when APS<0.

C Correct answer
Explanation

Aggregate demand curve is upward sloping showing a positive relation between level of income and overall expenditure in the economy. The curve intercepts on Y-axis because even at zero level of income, there is some consumption which is required for the very existence of life.

  1. APS, APC

  2. MPG, APS

  3. APC, APS

  4. MPS, APC
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

APC refers to Average Propensity to Consume which defines the amount of consumption in every 1 rupee of income for all level of income which can never be negative because consumption is never negative owing to the very existence of life and basic needs to satisfy it while it can be more than one as long as consumption is more national income, i.e. before the break-even point, APC > 1. 

Marginal Propensity to save refers to the percentage change in savings for every one rupee of change in the income. It is the ratio between the change in income and its corresponding change in savings. It can never be negative as it is a change in the value when the value of income changes while it can be equal to one if the overall change in the value of income is used in savings.

A Correct answer
Explanation

APC refers to Average Propensity to Consume which defines the amount of consumption in every 1 rupee of income for all level of income. Therefore,

APC= Consumption/ National Income= C/Y.

B Correct answer
Explanation

C= c+ bY where c=autonomous consumption, b= marginal propensity to consume, and Y= income. 

Multiple choice economics consumption and investment functions determinants of consumption function and savings function production, consumption, saving and economic units ex ante and ex post

If $C = 100 + 0.75\,Y$, then Saving Function will be expressed as:

  1. $S=100 +0.25\,Y$
  2. $S=100 + 0.75\,Y$
  3. $S = 100 + 0.35\,Y$
  4. $S =75+0.25\,Y$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The consumption function is C= 100+0.75Y where Y is the income at different level in the economy. 

Income = consumption + savings 

=> Savings = Income - consumption 

=> S = Y- C

=> S = Y - ( 100 + 0.75Y)

=> S = Y- 100 - 0.75Y

=> S = - 100 + Y ( 1 - 0.75) 

=> S = -100 + 0.25Y 

Therefore, the saving function is S= -100 + 0.25Y  where autonomous savings= -100, MPS= 0.25 and Y is income at all levels.
