Demand pull inflation arises where there is an increase in aggregate demand[?] in an economy relative to aggregate supply[?]. This is commonly described as "too much money chasing too few goods[?]". This would not be expected to persist over time due to increases in supply, unless the economy is already at a full employment level.
The term demand pull inflation is mostly associated with Keynesian economics.
