Following a significant increase in government expenditure on infrastructure and a sharp rise in household consumption due to higher disposable incomes, the general price level in the economy rises steadily. This scenario BEST illustrates which type of inflation? 

Demand-pull inflation arises when aggregate demand in an economy exceeds aggregate supply — often described as too much money chasing too few goods. In the given scenario, increased government expenditure and higher consumer spending raise aggregate demand beyond the economy's productive capacity, pulling prices upward. Cost-push inflation originates from the supply side through rising raw material costs or wages. Stagflation is a simultaneous occurrence of stagnant growth and high inflation. Structural inflation arises from supply bottlenecks and rigidities. Built-in inflation occurs when workers demand higher wages in anticipation of inflation, creating a wageprice spiral.
