• B. A decrease in nominal wages during inflation that raises firms' profits.

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the concept of inflation tax. Inflation tax refers to the loss in the real value or purchasing power of money holdings due to inflation. When prices rise, the money you hold buys less than before, which acts like a tax on holding money.
2. Step 2: Recognize that inflation tax is not a formal tax imposed by the government, but rather an implicit cost borne by holders of nominal assets (like cash) because inflation erodes their value.
3. Step 3: Compare the given options to the definition of inflation tax. The correct description should highlight the reduction in real purchasing power of money holdings caused by inflation, effectively transferring wealth from money holders to the issuer of money (usually the government).
4. Step 4: Identify why other options are incorrect: a decrease in nominal wages raising profits is unrelated to inflation tax; a one-time capital gains tax due to inflation is a different concept; and a government-imposed sales tax that rises with inflation is a formal tax, not an inflation tax.
5. Step 5: Conclude that the best description of inflation tax is the reduction in the real purchasing power of money holdings caused by inflation, which acts as a transfer of resources from money holders to the issuer of money.
