D Correct answer
Explanation

Aggregate Demand refers to the desired level of expenditure in the economy during an accounting year. It is what people wish to spend on the purchase of goods and services during an accounting year.

The Ad curve in income determination analysis represents a two sector economy which only includes the expenditure made by the consumer sector and the producer sector.
Therefore, aggregate demand = consumption + investment. 

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 saving function of an economy is given as: S = - 40 + 0.4 M, then MPC is ___________________.

  1. 1

  2. 0.4

  3. 0.8

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Saving function is S= s + M(1-b) where s=autonomous savings, (1-b)= marginal propensity to save, and M= income. Comparing it to S=−40+0.4(M), MPS= 0.4.


We know that, 

MPS + MPC = 1 

=> MPC = 1 - MPS 

=> MPC = 1 - 0.4 

=> MPC = 0.6 


Therefore, MPC is 0.6. 

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

Which among the following is the other term used for 'saving function'?

  1. Income function

  2. Propensity to save

  3. Reverse consumption propensity

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Savings function refers to the standard equation of savings which defines the relationship between savings and income where savings value can be derived at each level with the use of income value. 

S= s + Y(1-b) where s=autonomous savings, (1-b)= marginal propensity to save, and Y= income.

It defines the propensity to save in the economy at every level of 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

When the savings curve lies below the x-axis, the consumption is higher than the income leading to dissaving.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Average Propensity to save defines the amount of savings in every 1 rupee of income for all level of income which can be less than zero at income levels which are lower than the break-even point where savings lies below the x-axis indicating that consumption is greater than income that leads to dissavings in the economy.

Reveal answer Fill a bubble to check yourself
B 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. It is expressed as the ration of saving to income in an economy. 

Average propensity to save = S/Y where S is the savings and Y is the income in the economy. 

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

Which among the following is a type of propensity to save?

  1. Marginal propensity to save

  2. Average propensity to save

  3. Total propensity to save

  4. Both A & B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

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.

Marginal propensity to save = ΔS/ΔY where ΔS is the Change in savings and ΔY is the change in income in the economy. 

APS refers to Average Propensity to save which defines the amount of savings in every 1 rupee of income for all level of income. 

Average propensity to save = S/Y where S is the savings and Y is the income in the economy.
