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)
