It is positively related to the price level. Here, long-run aggregate supply is not dependent upon the price level in the economy, hence it does not vary with the price level. The long-run aggregate supply curve is vertical because the economy’s potential output is set by the availability and productivity of real resources instead of price. The LRAS curve intersects the horizontal axis where the factors of production are used in the most efficient manner, which is called the full employment output or the natural level of output. The long-run aggregate supply (LRAS) curve is vertical because the price level has no bearing on the economy’s long-run potential.

Explain why long-run aggregate supply is vertical at a particular level of output. Neoclassical economists argue that the long-run aggregate supply curve is located at potential GDP—that is, the long-run aggregate supply curve is a vertical line drawn at the level of potential GDP, as shown in Figure 2. The long-run aggregate-supply curve is consistent with this idea because it implies that the quantity of output (a real variable) does not depend on the level of prices (a nominal variable).

The Long-Run Aggregate Supply (LAS) represents the relationship between the price level and output in the long-run.It differs from the Short-Run Aggregate Supply (SAS) in that no input prices are assumed to be constant. What defines the quantity of goods and services supplied in the long-run? The availability and productivity of real resources is reflected by price inputs and in long run price inputs which includes wages which adjust to match changes in the price level. The long-run aggregate supply curve can be shifted, when the factors of production change in quantity. GDP remained at $\$ 15$ trillion even though there was a change in the price level from 100 to $110,$ and from 110 to 120 . So, price ceases to matter, it can’t increase GDP.
