Study Notes

Difficulties in Constructing Index Numbers

Choosing a base year is challenging because it needs to be consistent and not change frequently
Selecting representative commodities is difficult due to changing consumer consumption patterns
Obtaining accurate prices is difficult because prices can vary between locations and retailers. Index numbers often rely on wholesale prices
Determining the best statistical approach for calculating index numbers is challenging as different approaches can result in different outcomes
Changes over time due to technological advancements present a challenge as commodities can change, and new commodities are not always included in calculations
It is impossible to compare index numbers from different countries because the goods and services included in the basket of goods can vary
It is impossible to compare index numbers across different locations within a country because of differences in consumption patterns

Importance of Index Numbers

Index numbers are essential for studying the economic situation of a region
Provide a relative measure of change in a variable over time
Useful for measuring change in factors that cannot be directly measured or estimated

Features of Index Numbers

A type of average that measures relative changes rather than absolute changes
Used to study changes in factors that cannot be measured directly e.g. the general price level
Measures change in one variable or a group of variables
Comparisons can be made over time or across different locations

Types of Index Numbers

Value Index measures changes in the aggregate value of goods and services (e.g. inventory, sales, foreign trade)
Quantity Index measures changes in the volume or quantity of goods produced, consumed, or sold (e.g. Index of Industrial Production)
Price Index measures changes in the price of goods and services over a period of time (e.g. Consumer Price Index, Wholesale Price Index)
