Question: Direction Read the following case study and answer the question no. (i) to (vi) on the basis of the same.
We frequently see index numbers, such as the Consumer Price Index (CPI), in our daily life.
Economists often use the index numbers to compare values measured at different points in time. Using an index can make quick comparisons
easy. The index numbers have become a widely accepted statistical device for measuring business activity changes. A typical use of the index
number technique in business is to summarize complex situations with a single performance index so that a dashboard (or report) would have enough space to show all KPIs. An index number is used to measure changes in the magnitude of a variable or group of variables regarding time,geographical location, or other characteristics such as profession.
IT professionals who need to analyse economic and business activities, but have limited experience in statistics, want to learn how to construct and interpret performance indexes. Index numbers are also not free from criticism as its base year and commodity selection requires a lot of attention and expert attention.

(d) All of these 

Answer: A

 

Short Answer Type Questions

Question: Is the change in any price reflected in a price index number?
Answer: No, the change in any price is not reflected in a price index number. Price index numbers measure and permit comparison of the prices of certain goods included in the basket being used to compare prices in the base period with prices in the current period. Moreover, an equal rise in the price of an item with large weight and that of an item with low weight will have different implications for the overall change in the price index.

Question: Why do we need an index number?
Answer:Index numbers are needed because of the various advantages which pertain to the use of index numbers.
These advantages
(i) Barometer of Economic Progress Index numbers are a barometer for measuring the value of money and assessing the level of economic progress.
(ii) Importance for the Government The government adopts suitable monetary and fiscal policies according to the changes in index numbers.
(iii) Throws Light on Economic Condition Index numbers are very helpful in comparing the economic condition of a particular group of people
across two time periods.
(iv) Fixation ofWages of Policy-making Index numbers such as CPI andWPI help the government and executives for the fixation and revision of wages.

Question: What are the desirable properties of the base period?
Answer: Base period should have the following properties 
(i) The base year should be a normal year in which extraordinary events such as earthquake, flood, war, elections, etc should not have occurred.
(ii) The period should not be too far in the past as comparison cannot be done with such a base year because policies, economic and social conditions
change with time.
(iii) Base period should be updated periodically.
Thus, we can conclude that while selecting base period, certain factors should be considered.

Question: If the salary of a person in the base year is ` 4,000 per annum and the current year salary is ` 6,000, by how much should his salary rise to maintain the same standard of living, if the CPI is 400?
Answer: Base year salary = ` 4,000, Base year index = 100 (assumption), Current year index = 400 Salary required in the current year to maintain the same standard of living of base year = Base Year Salary × CPI of Current Year CPI of Base Year = 4 000 × 400 100 , = `16,000 Current year salary = ` 6,000 The increase in current salary required = 16,000 − 6,000 = ` 10,000

Question: What is the difference between a price index and a quantity index?
Answer: The differences between a price index and a quantity index are as follows (i) Price index numbers measure and allow for comparison of the prices of certain goods while quantity index numbers measure the changes in thephysical volume of production, construction or employment.
(ii) Price index numbers are more widely used as compared to quantity index numbers.
(iii) Quantity index does not indicate the real change in the purchasing power of money while price index does.

 

Question: Give the limitations of simple aggregative method of computing index number.
Answer:Although computation of index number is quite simple while using this method, yet it is not ordinarily used because of the following limitations
(i) All items are given equal weightage.
(ii) This measure of index number is influenced by the items which are highly priced.
(iii) This method is affected with the change in the unit of measurement.
For example, index number computed when price of wheat is expressed in per kg, will be different from the index number computed when the price of wheat is expressed in per quintal.

Question: Which method is considered ‘ideal’ for constructing index number and why?
Answer: Fisher’s method is considered ideal for constructing index number because
(i) It satisfies factor reversal test.
(ii) It satisfies time reversal test.
(iii) It is based on different weights.

Question: Mr Ashok was getting ` 400 in the base year and ` 800 in the current year. If Consumer Price Index is ` 350, then what extra amount is required for maintaining the earlier standard of living?
Answer: For former standard of living, Ashok should get = Salary in Base Year × CPI 100 = × = 400 350 100 1,400 \ Amount required for maintaining the same standard of living = 1,400 − 800 = ` 600

Question: Explain briefly the process of data collection for Consumer Price Index (CPI).
Answer: Primary data is collected every month to compute rural and urban CPI in the following ways (i) For CPI (Rural), two villages are selected from each
district. Presently data is collected from 1,181 villages. Number of items for price data collection is identified through the market survey and it is
around 225.
Price data is collected from selected shops in the villages every month by the Department of Posts.
 
(ii) For CPI (Urban), data is collected from all cities, having a population of more than 9 lakhs. Presently, total number of selected cities is 310. Number of items for price data collection is identified through the market survey and it is around 250. Each selected market is visited every month for price data collection from shops and outlets.

(iii) 4.75 lakh price data records collected from rural and urban areas are uploaded per month to the web portal of National Informatics Centre, which is the formal data collection arm of NSSO (National Sample Survey Organisation).

 Long Answer Type Questions


Question: Discuss in brief, the methods of constructing weighted index numbers.
Answer: Weighted index numbers are the index number in which different items of the series are accorded different weightage, depending upon their relative importance.
There are two methods of constructing weighted index numbers
(i) Weighted Average of Price Relative Method According to this method, weighted index number is simply the weighted arithmetic mean of price relative. In this method, weighted sum of the price relative is divided by the sum total of the weights.

Thus,       P01=[∑/W/∑W]

(ii) Weighted Aggregative Method Under this method,weights are assigned to various items and instead of finding the simple aggregate of price, the weighted aggregate of the price are obtained. The different methods to compute weighted aggregative index numbers are 

Laspeyre’s Method This method uses the base year quantities as weights.
The following formula is used to calculate index number

P01 = ∑P1q0/∑poq0x100

Paasche’s Method This method uses the current year quantities as weights The following formula is used to calculate index number

p01= ∑P1q1/∑poq1x100

Fisher’s Method This method combines the techniques of Laspeyre’s method and Paasche’s method and uses both base year as well as current year quantities
(q0 ,q1 ) as weight. The formula to construct index number is 

 p01= √∑P1q0/∑P0q0 x∑P1q1/∑P0qx 100 

Question: Explain briefly the various characteristics or features of index numbers.
Answer: The characteristics of index numbers are as follows 
(i) Specialised Averages Index numbers are specialised averages as they are helpful in computing combined averages of goods and services expressed in different units. Unlike the measures of central tendency, which can compute averages of variables expressed in one unit only, index numbers can measure the averages of variables with diverse units.

(ii) Measure the Relative Changes Index numbers measure the relative change in the value of the variable under study. Because of this, index numbers are expressed in terms of percentage which are independent of the units of measurement.

(iii) Measure the Net Changes Index numbers measure net changes in a variable or group of variables. They describe net change in a single number. This facilitates the comparisons of two or more index numbers.

(iv) Measure the Change not Capable of Direct Measurement Index numbers are meant to study the changes in the effects of such factors which cannot be measured directly. For example, changes in business activity in a country are not capable of direct measurement but it is possible to study relative changes in business activity with the help of index number.
