Question

Difficulty: MediumInflation Types, Price Indices (CPI, WPI), and Price Control Mechanisms

With reference to economic concepts related to inflation dynamics and price controls, consider the following statements:

1. Inflation tax refers to the implicit economic penalty borne by individuals holding cash balances, as rising price levels erode purchasing power and effectively transfer real resources to net debtors.
2. Disinflation describes a economic condition where the general price level of goods and services persistently declines below zero over time.
3. Core inflation measures general price level changes while excluding volatile commodity groups such as food and energy items.

Which of the statements given above is/are correct?

  1. 1 and 3 onlyAnswer
  2. B
    1 only
  3. C
    2 and 3 only
  4. D
    1, 2 and 3

Answer

Statements 1 and 3 are correct.
The correct answer identifies that Statement 1 and Statement 3 are correct. Inflation tax refers to the loss of purchasing power on money held during inflationary periods, effectively benefiting net debtors. Core inflation isolates non-volatile economic price changes by excluding food and energy elements. Statement 2 is false because a negative rate of inflation is termed deflation, whereas disinflation simply means a slowdown in positive inflation.

Step-by-Step Solution

1
Evaluate Statement 1 regarding inflation tax.
Inflation tax is the financial loss incurred by cash holders during inflation. As price levels increase, the real value of uninvested currency declines, which acts as a transfer of real purchasing power from cash holders to net debtors (like government issuers of fiat currency). Thus, Statement 1 is correct.
Inflation diminishes the real purchasing power of monetary units.
2
Evaluate Statement 2 regarding disinflation.
Disinflation refers to a slowdown in the rate of inflation (e.g., inflation falling from 6% to 3%), while price levels continue to rise at a slower pace. Deflation, not disinflation, refers to a period where general price levels drop below zero. Thus, Statement 2 is incorrect.
Distinguishing between a decline in the rate of inflation and an absolute fall in general price levels.
3
Evaluate Statement 3 regarding core inflation.
Core inflation is calculated by taking headline consumer inflation and removing volatile components like food and fuel/energy prices to reflect underlying long-term price trends. Thus, Statement 3 is correct.
Core inflation isolates non-volatile structural price changes.
