Definition

Money Illusion refers to the psychological phenomenon where individuals perceive an increase in their nominal income as an enhancement of their real purchasing power, without considering that price level increases (inflation) have nullified the actual buying power. It highlights the failure to distinguish between nominal and real values in monetary terms.

Examples

  1. Salary Increase During Inflationary Period: An employee receives a 5% raise but fails to recognize that the inflation rate has also increased by 5%. The higher salary does not boost their purchasing power because the cost of goods and services has also risen proportionally.

  2. Historical Example: In the Weimar Republic hyperinflation, workers demanded higher wages which they received in increasing amounts of currency, but because prices of goods skyrocketed concurrently, their actual purchasing power didn’t improve.

  3. Stock Market Returns: Investors may feel richer if their investments yield a return of 10%, but if inflation is also 10%, their real gain in purchasing power is zero.
