This article explains the aggregate demand and aggregate supply curves in macroeconomics, including their definitions and how they interact to determine equilibrium.
Oct 7, 2024 · A shift to the left or reduction in aggregate demand is perceived negatively utilizing the aggregate demand curve while an increase in aggregate demand or a shift to the right is...
Mar 1, 2022 · A good understanding of what shifts aggregate demand and aggregate supply, as well as the curves, different economic theories around them, and how they are practically applied will boost your confidence as you approach the exam.
Key points. Aggregate supply is the total quantity of output firms will produce and sell—in other words, the real GDP. The upward-sloping aggregate supply curve —also known as the short run aggregate supply curve —shows the positive relationship between price level and real GDP in the short run.
- Long-Run Aggregate Supply. The long-run aggregate supply (LRAS) curve relates the level of output produced by firms to the price level in the long run. In Panel (b) of Figure 22.5 “Natural Employment and Long-Run Aggregate Supply”, the long-run aggregate supply curve is a vertical line at the economy’s potential level of output.
- Equilibrium Levels of Price and Output in the Long Run. The intersection of the economy’s aggregate demand curve and the long-run aggregate supply curve determines its equilibrium real GDP and price level in the long run.
- Short-Run Aggregate Supply. Figure 22.7 Deriving the Short-Run Aggregate Supply Curve. The economy shown here is in long-run equilibrium at the intersection of AD1 with the long-run aggregate supply curve.
- Reasons for Wage and Price Stickiness. Wage or price stickiness means that the economy may not always be operating at potential. Rather, the economy may operate either above or below potential output in the short run.

The AD-AS (aggregate demand-aggregate supply) model is a way of illustrating national income determination and changes in the price level. We can use this to illustrate phases of the business cycle and how different events can lead to changes in two of our key macroeconomic indicators: real GDP and inflation.
