Aggregate demand-aggregate supply model

Beyond Y ∗ {\displaystyle Y^{*}}, this gets more intense, so that price increases dominate. Worse, output levels greater than Y ∗ {\displaystyle Y^{*}} cannot be sustained for long. The A S {\displaystyle AS} is a short-term relationship here. If the economy persists in operating above potential, the A S {\displaystyle AS} curve will shift to the left, making the increases in real output transitory.
