Final answer:
The natural rate of output on the vertical long-run aggregate supply curve is not influenced by monetary policy, fiscal policy, or demand shocks.
Step-by-step explanation:
The vertical long-run aggregate supply curve (LRAS) satisfies the classical dichotomy by indicating that the natural rate of output is not affected by monetary policy, fiscal policy, or demand shocks.
Instead, it is only influenced by factors that affect the potential or natural level of output, such as technology and resource availability.
Neoclassical economists argue that since the LRAS is vertical, any shifts in aggregate demand impact only the price level and not the output or unemployment in the long run. Consequently, the correct answer to the student's question is that the natural rate of output does not depend on monetary policy, fiscal policy, or demand shocks.
Neither fiscal nor monetary policy can have a long-term impact on the natural rate of output or employment levels, which are determined by supply-side factors.
