demand-pull inflation

Think of an auction with one painting and a room full of eager bidders flush with cash. The painting did not change, and there is only one of it, yet the price soars because so many people want it and can pay. Now widen that to a whole economy: when everyone wants to buy more than the economy can readily make, prices across the board get bid up. That is demand-pull inflation — too much demand chasing too few goods.

Demand-pull inflation occurs when aggregate demand grows faster than the economy's ability to produce, so the general price level is pulled upward. It is the classic phrase "too much money chasing too few goods." Demand can surge for many reasons: rising wages and confidence, a wave of borrowing and spending, government stimulus, low interest rates, or a jump in exports. When the economy is already near full capacity, firms cannot easily make more, so they raise prices instead, and inflation follows.

Demand-pull inflation tends to come with a hot economy — low unemployment, busy factories, brisk hiring — which is why it is sometimes called "good" inflation, the byproduct of a boom. But left unchecked it overheats, and central banks respond by raising interest rates to cool spending. The honest caveat: real-world inflation is rarely purely demand-pull or purely cost-push; the two often feed each other, and untangling which is driving a given inflation episode is a genuine and contested judgment call.
