Equilibrium Output and the Price Level

The AD-SRAS model shows how total output and the price level are determined in the short run.

On the graph, the aggregate demand curve slopes downward. This happens because when the price level rises, the real value of money falls, so people can afford to buy fewer goods and services. As a result, households and businesses tend to reduce their spending. Also, higher price levels can raise interest rates and reduce exports, which further lowers aggregate demand.

On the other hand, the short-run aggregate supply curve slopes upward. This is driven by profit incentives, because when price levels rise, producing and selling goods becomes more lucrative. This motivates firms to hire more workers and increase production.

The point where these two curves intersect is the economy’s equilibrium. At this specific point, the total amount buyers wish to purchase exactly equals the amount firms are willing to sell.

On the graph, we label this intersection as "Y" for equilibrium output and "P" for the equilibrium price level. These coordinates define the stable market outcome.

This intersection shows the economy’s stable short-run equilibrium.
