Background
Indexation refers to an economic mechanism whereby monetary values such as wages, prices, or interest payments are adjusted in proportion to a selected price index. This adjustment mechanism aims to stabilize real income and maintain purchasing power in the face of inflationary pressures.
Historical Context
The concept of indexation first gained widespread attention in the 20th century as economies around the world grappled with inflation. The practice started with the adjustment of wages and pensions to counter the effects of inflation, ensuring that the value of money remained relatively stable over time.
Definitions and Concepts
Indexation is defined as a system where monetary values are not fixed in absolute money terms but are automatically adjusted based on a specific price index. Common indices used for adjustment include the Consumer Price Index (CPI), Wholesale Price Index (WPI), and other inflation measures. By linking financial variables to these indices, indexation helps mitigate the adverse effects of inflation on purchasing power.
Major Analytical Frameworks
Classical Economics
Classical economists often ignored indexation, focusing instead on the long-term equilibrium state of the economy. However, they acknowledged the disruptive potential of inflation and the occasional introduction of price adjustments to maintain economic stability.
Neoclassical Economics
Neoclassical economics embraces indexation as a method to reduce uncertainty and correct misallocations caused by inflation. It portrays indexation as an important tool for keeping economic variables stable in the short term.
Keynesian Economics
Keynesian economists view indexation as a pragmatic response to inflation. They argue that automatic adjustments can help stabilize real wages and consumption, aiding in economic stability during inflationary periods.
Marxian Economics
Marxian analysis might critique indexation as a method that disguises the exploitative aspects of capitalism. While it appears to stabilize real wages, deeper issues related to income inequality and exploitation remain unresolved.
Institutional Economics
Institutional economists highlight that indexation relies heavily on the structure and efficiency of the institutions involved. The effectiveness of indexation therefore depends on regulatory frameworks and the precision of the indices used.
Behavioral Economics
Behavioral economists examine the psychological and decision-making impacts of indexation on individuals. They investigate how knowledge of future price adjustments influences spending and saving behaviors.
Post-Keynesian Economics
Post-Keynesian economists are skeptical of indexation, arguing that it may entrench inflationary expectations and behaviors. They suggest that indexing might lead to a self-fulfilling cycle of continuous price and wage increases.
Austrian Economics
Austrian economists often criticize indexation for interfering with natural market mechanisms. They argue that the market should be allowed to adjust freely without government-imposed indexation schemes.
Development Economics
Within development economics, indexation is considered crucial for safeguarding incomes in developing nations prone to high inflation. It can protect vulnerable populations by ensuring that their purchasing power is maintained amidst economic volatility.
Monetarism
Monetarists see indexation as important within the context of controlling money supply. They argue it can help prevent wage-price spirals that could exacerbate inflation, providing a layer of stability in monetary policy.
Comparative Analysis
The effectiveness and desirability of indexation depend on the economic context and the objectives of policy-makers. For instance, while highly effective in stabilizing real incomes in inflatory environments, it may lock economies into inflationary spirals without being accompanied by comprehensive anti-inflation measures.

- Brazil in the 1990s: Brazil implemented a widespread indexation system to counter hyperinflation.
- United States Social Security: U.S. Social Security payments are indexed to the Consumer Price Index.

Related Terms with Definitions
- Consumer Price Index (CPI): A measure that examines the weighted average of prices of a basket of consumer goods and services.
- Inflation: The rate at which the general level of prices for goods and services rises, eroding purchasing power.
- Purchasing Power: The value of a currency expressed in terms of the amount of goods or services that one unit of money can buy.
By understanding indexation, its various applications, and the theoretical frameworks underpinning its use, one can better appreciate how economies attempt to maintain stability in the face of inflation and economic changes.
