Q:

The long run aggregate supply curve is vertical because

A) there is no cyclical inflation B) potential GDP is low
C) at full employment prices are stable D) all of the above
 
Answer & Explanation Answer: C) at full employment prices are stable

Explanation:

The long-run aggregate supply curve is vertical because it is at the full-employment or potential output. Because the economy's potential output is determined by the availability and productivity of real resources, not by the price level. That means that even if demand increases, firms can't hire new workers and expand because everyone is already working.
