What is the cause of demand pull inflation?

Question

Accepted Answer

The correct option is 4:

Demand-pull inflation occurs when the aggregate demand (total spending) in an economy significantly outweighs the aggregate supply (total production capacity), causing prices to rise. A substantial increase in population, especially when accompanied by an increase in income per capita or simply a fixed supply of goods and services, acts as a powerful driver for aggregate demand. More people mean more consumers demanding goods and services, leading to greater competition for the available output. If the economy cannot quickly increase production to meet this surge in demand, the resulting excess demand "pulls" prices upward across the board. This dynamic is a classic cause of demand-pull inflation, where "too much money is chasing too few goods."

The incorrect option is 1:
Decrease in production is a primary cause of *cost-push* inflation, not demand-pull inflation. If production falls, supply shrinks, pushing prices up due to scarcity, even if demand levels remain the same.

The incorrect option is 2:
Increase in cost, such as higher wages or raw material prices, directly causes *cost-push* inflation. Firms pass these higher input costs onto consumers in the form of higher prices, which is a supply-side phenomenon.

The incorrect option is 3:
High taxation, particularly on consumption (like GST or sales tax) or income, generally *decreases* disposable income and aggregate demand. Therefore, high taxation tends to be a measure used to combat inflation, or it may slow down price increases, making it the opposite of a cause for demand-pull inflation.
