  4. Family budget method formula
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

$\Rightarrow$  Consumer price index are obtained by: $Family\,\,budget\,\,method\,\,formula.$

$\Rightarrow$  In this method, the family budgets of a large number of people are carefully studied and the aggregate expenditure of the average family for various items is estimated. 
$\Rightarrow$  These values are used as weights. The current year’s prices are converted into price relatives on the basis of the base year’s prices, and these price relatives are multiplied by the respective values of the commodities in the base year. The total of these products is divided by the sum of the weights and the resulting figure is the required index numbers.
$P _{0n}=\dfrac{\sum WI}{\sum W}$   Here, $I=\dfrac{P _n}{P _0}\times 100$  and $W=P _0q _0$

  1. level of investments.

  2. level of savings.

  3. level of income.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The relationship between consumption and the level of income is called consumption function. Consumption function tells that consumption is a function of income, or in other words, consumption depends on the level of income.

Aggregate consumption of all depends on the total income generated in the economy. When the total income of the economy increases total consumption of the economy will also increase. In the same way, it can also be said that economy with higher level of national income consumes more than the economy which has lower level of national income.

Consumption depends on which of the following?

  1. Total Savings

  2. Needs

  3. Total Income

  4. Total Disposable Income
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Everybody needs income to purchase goods and services. Higher the level of income, higher will be the capacity to buy the goods and services. So for an individual, the total amount of goods and services to be purchased depends on the available disposable income.

Similarly, for an economy as a whole, it can be said that the aggregate consumption of all depends on the total income generated in the economy. When the total income of the economy increases total consumption of the economy will also increase. When we refer to income, we normally mean disposable income. Disposable income is that part of total income which is available for consumption and saving.

Disposable income is defined as the income remained after payment of taxes and fines. If tax payment in high, disposable income will be lower and vice versa.

Which of the following factors don't affect the propensity to consume in an economy?

  1. Rate of interest

  2. Wealth

  3. Taxes

  4. Consumer credit
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The factors that influence consumption and savings behaviour in the economy are as follows:

Rate of interest: Commercial bank offer a certain rate of interest on the deposits held by public and charges rate of interest on the loans given to public. When people do not want to purchase goods and services, they keep their money in the bank to earn the rate of interest. But when they want to buy goods and services, they withdraw money from the bank and lose interest in the process. In this way, the rate of interest plays an important role in influencing a persons decision to consume.

Wealth: Propensity to consume is influenced by a persons holding of wealth. People who have wealth in the form of gold, jewellery, ownership of land and building, shares and bonds etc enjoy a higher level of income generated from the wealth. Accordingly, their consumption level will be higher.

Consumer credit: Availability of consumer credit influences consumption behaviour to a large extent in the economy. There are many durable goods which consumers want to buy. But due to lack of credit facility, they are not able to buy them as they are costly items.

  1. APC and MPC

  2. APS AND MPS

  3. Demand and Supply

  4. Income and consumption
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In dealing with Propensity to consume, Keynes considered two attributes: 

1. APC : APC refers to Average Propensity to Consume which defines the amount of consumption in every 1 rupee of income for all level of income. 
Average propensity to consume = C/Y where C is the consumption and Y is the income in the economy 

2. MPC: Marginal Propensity to consume refers to the percentage change in consumption for every one rupee of change in the income. It is the ratio between the change in income and corresponding change in consumption.
Marginal propensity to consume = ΔC/ΔY where ΔC is the Change in consumption and ΔY is the change in income in the economy.

Explanation

A schedule of propensity to consume refers to a statement that shows the functional relationship between the level of aggregate consumption and aggregate income in the economy at each level of output produced. 

In dealing with Propensity to consume, Keynes considered two attributes: 
1. APC : APC refers to Average Propensity to Consume which defines the amount of consumption in every 1 rupee of income for all level of income. 

Average propensity to consume = C/Y where C is the consumption and Y is the income in the economy 

2. MPC : Marginal Propensity to consume refers to the percentage change in consumption for every one rupee of change in the income. It is the ratio between the change in income and corresponding change in consumption.
