Indexation is a fundamental concept in economics and finance that provides a method for adjusting wages, prices, or the interest and redemption payments on securities in proportion to a suitable index of prices, such as the retail price index. This adjustment aims to stabilize real incomes and income differentials.
Historical Context
The idea of indexation has evolved over time, particularly during periods of high inflation when the purchasing power of money can erode rapidly. Historical examples include:
- Post-World War II Era: Governments sought methods to protect the real value of wages and pensions against inflation.
- 1970s: High inflation rates led many countries to adopt indexation for various economic indicators.
Types/Categories of Indexation
Indexation can be categorized based on its application:
- Wage Indexation: Adjusting wages in line with the cost of living index to maintain the purchasing power of employees.
- Price Indexation: Linking prices of goods and services to a price index to maintain stability.
- Pension Indexation: Adjusting pension payments based either on price indices or wage rates.
- Security Indexation: Adjusting interest and redemption payments on bonds or other financial instruments according to a price index.
Key Events
Some key events in the history of indexation include:
- The 1970s Energy Crisis: This led to widespread adoption of indexation in various countries as a response to surging inflation.
- Introduction of Inflation-Linked Bonds: Governments issued bonds that were indexed to inflation to protect investors from inflation risk.
Detailed Explanations
Mechanism of Indexation
Indexation works by linking payments to an index, which is a statistical measure of changes in a representative group of individual data points. For example:
- Formula for Wage Indexation:
$$ W = W_0 \times \frac{I_1}{I_0} $$where \(W\) is the adjusted wage, \(W_0\) is the initial wage, \(I_1\) is the new index value, and \(I_0\) is the original index value.
Example of Price Indexation:
- Consumer Price Index (CPI):
$$ \text{CPI} = \frac{\sum (\text{Price of Current Year} \times \text{Quantity})}{\sum (\text{Price of Base Year} \times \text{Quantity})} \times 100 $$

Importance and Applicability
Indexation is crucial in several contexts:
- Economic Stability: Helps maintain the real value of incomes and payments during inflation.
- Social Equity: Protects the purchasing power of pensions and social security benefits.
- Investment Security: Provides inflation-protection to investors through index-linked securities.
Examples
- Wage Contracts: Contracts that include clauses adjusting wages based on inflation measures.
- Indexed Bonds: Government bonds that are linked to inflation indices to protect investors.
Considerations
- Time Lags: The effectiveness of indexation can be diminished by time lags between the change in the index and the adjustment.
- Economic Impact: Over-indexation can lead to inflationary spirals, whereas under-indexation can result in reduced real incomes.
Related Terms
- Inflation: General increase in prices and fall in the purchasing value of money.
- Deflation: Reduction of the general level of prices in an economy.
- Real Income: Income of individuals or nations after adjusting for inflation.
Comparisons
- Indexation vs. Fixed Rates: Fixed rates do not adjust for inflation, potentially reducing real income value, whereas indexation provides inflation protection.
- Automatic vs. Discretionary Adjustments: Automatic adjustments are predetermined, while discretionary adjustments depend on decisions made by authorities.
Interesting Facts
- TIPS (Treasury Inflation-Protected Securities): U.S. government bonds specifically designed to protect investors from inflation.
- Chilean UF: An inflation-indexed unit of account used in Chile to price everything from real estate to university tuition fees.

- Chilean Economy: The adoption of the Unidad de Fomento (UF) helped stabilize the Chilean economy during high inflation periods, providing a model for other nations.
Famous Quotes
- John Maynard Keynes: “By a continuing process of inflation, governments can confiscate, secretly and unobserved, an important part of the wealth of their citizens.”

- “A penny saved is a penny earned” - highlighting the importance of maintaining the value of money through methods like indexation.

Final Summary
Indexation is an essential economic tool designed to safeguard the real value of wages, prices, pensions, and securities against inflation. By linking these financial elements to suitable indices, indexation helps maintain economic stability and protect individuals’ purchasing power.
