Real prices are prices that have been adjusted for inflation, representing the true cost in constant dollars. Unlike nominal prices, which reflect the current market price without adjustment, real prices offer a clearer picture of purchasing power over time.
Historical Context
The concept of real prices emerged as economists and analysts sought better ways to compare the value of money across different periods. Inflation, the general increase in prices and decrease in the purchasing power of money, can distort economic analysis if not accounted for. By adjusting for inflation, real prices provide a more accurate reflection of an asset’s value or a consumer’s purchasing power over time.
Types of Prices
- Nominal Prices: Current market prices without adjustments.
- Real Prices: Prices adjusted for inflation, reflecting the constant dollar value.
Key Events
- Introduction of Consumer Price Index (CPI): The CPI is one of the primary tools used to adjust nominal prices to real prices, allowing for inflation-adjusted comparisons.
- Economic Research in the 20th Century: As economic theories developed, the importance of considering inflation in price analysis became more prominent.
Detailed Explanations
