Q.Explain the relationship between the value of money and the general price level.

The value of money means its purchasing power, and it is measured against the price level, which the two move opposite to.

The value of money is its purchasing power — the quantity of goods and services a unit of money can buy. It is always judged against the general price level, which is the average of the prices of goods and services measured by an index number (WPI or CPI) against a base year of 100.

The relationship between the two is inverse, expressed as:

• When the general price level rises (inflation), a given sum of money buys fewer goods, so the value of money falls.
• When the general price level falls (deflation), the same money buys more goods, so the value of money rises.

For example, if a price index rises from 100 to 125, prices are 25% higher and the value of money falls to about 100/125 = 0.80, i.e. money buys only 80% of what it earlier could. Thus 'rising prices' and 'falling value of money' describe the very same event from two angles.

Students sometimes state the relationship as direct rather than inverse. Anchor the idea with a concrete example: if the price of everything doubles, your rupee buys half as much, so its value has halved — clearly opposite to the price level.
