Hidden Inflation
Hidden inflation is an informal label for effective price increases obscured by smaller packages, lower service, added fees, or quality changes; learn how to calculate and evaluate it.
Compare inflation-rate calculations, output gaps, feedback spirals, hidden effective price increases, and inflation suppressed by price controls.
Inflation Rates, Gaps, and Suppressed Prices connects observed price-index changes with the capacity gaps, feedback processes, controls, and less-visible commercial price changes that can complicate interpretation.
The pages do not describe interchangeable forms of inflation. They answer different questions: how fast a price index changed, whether demand exceeds estimated capacity, how inflation can reinforce itself, and why a posted or controlled price may omit part of the economic cost.
| Page | Use it for |
|---|---|
| Inflation Rate | Monthly, annualized, 12-month, cumulative, average, and point-to-point price-index calculations |
| Inflationary Gap | Model-based demand or output pressure relative to estimated sustainable capacity |
| Inflationary Spiral | Feedback among prices, wages, costs, exchange rates, expectations, and policy |
| Hidden Inflation | Informal commercial pricing through package size, included service, product quality, or mandatory fees |
| Repressed Inflation | Binding price controls, rationing, shortages, shadow prices, subsidies, and decontrol effects |
| Observation | Correct starting interpretation |
|---|---|
| CPI rises 3% over 12 months | A measured inflation rate; the cause still requires analysis |
| Actual output exceeds estimated potential | A positive output gap that may create demand pressure; potential output is uncertain |
| Wages and prices repeatedly react to each other | Possible feedback process; timing and productivity still matter |
| Package size falls at the same shelf price | Higher unit price, which a statistical agency may capture |
| Official price is fixed but shelves are empty | Possible binding control and shortage; quantity and non-price allocation matter |
| Control ends and the price jumps once | Price-level adjustment, not automatically a permanently higher inflation rate |

These pages provide general financial education, not a price forecast, legal interpretation of controls or fees, policy recommendation, or personalized investment or purchasing advice.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.
Hidden inflation is an informal label for effective price increases obscured by smaller packages, lower service, added fees, or quality changes; learn how to calculate and evaluate it.
The inflation rate is the percentage change in a specified price index over a stated period, used to measure changes in the general price level.
An inflationary gap is a positive output gap in which actual real GDP exceeds estimated potential GDP. Learn the calculation, signals, and limitations.
An inflationary spiral is a feedback process in which prices, wages, costs, expectations, or exchange rates generate additional inflation.
Repressed inflation occurs when binding controls suppress observed prices while excess demand remains; learn shortage mechanics, shadow prices, decontrol effects, and policy risks.
