Final answer:
The long-run AD/AS model of equilibrium has a limitation in identifying the long-run equilibrium level of output due to changes in aggregate demand.
Step-by-step explanation:
One of the primary limitations of the long-run AD/AS model of equilibrium is that changes in aggregate demand do not allow identification of the long-run equilibrium level of output. This is because the long-run AD/AS model assumes that the economy has fully adjusted to any changes in aggregate demand, meaning there is no further room for output to increase or decrease. In reality, the long-run equilibrium level of output may vary due to factors such as technological advancements, changes in labor force, and shifts in long-run aggregate supply.
