Without government intervention, how is the new long-run equilibrium different from the initial one? Group of answer choices the price level is higher and the unemployment rate is the same. the price level is the same and the unemployment rate is higher. both the price level and the unemployment rate are higher. both the price level and the unemployment rate are lower.
The correct answer and explanation is:
The correct answer is:
the price level is higher and the unemployment rate is the same.
Explanation (300 words):
In macroeconomics, the concept of long-run equilibrium refers to a state where the economy’s output returns to its natural level (potential output), and unemployment is at its natural rate, regardless of price level changes.
When there is a shock to the economy—such as an increase in aggregate demand or aggregate supply—prices and output may deviate from their initial long-run equilibrium temporarily. However, without government intervention (like fiscal or monetary policy), the economy self-adjusts over time.
Why does the price level change but unemployment returns to normal?
- Initially, an increase in aggregate demand (for example) pushes output above the natural level, lowering unemployment below its natural rate. However, firms face higher costs (wages, resource prices), and workers eventually adjust their expectations for inflation.
- Over time, as wages and prices adjust upward due to these expectations, the short-run aggregate supply curve shifts leftward. This process increases the overall price level.
- The economy settles back to its natural output level because output cannot sustainably exceed potential output in the long run.
- Since output returns to the natural level, the unemployment rate also returns to the natural rate — the level consistent with full employment but not zero unemployment.
- The key difference is that the overall price level is now higher than it was initially because of the upward adjustment in wages and costs.
Thus, the long-run adjustment process leads to a higher price level but leaves the unemployment rate unchanged, as the economy returns to its natural rate of unemployment.
In summary: Without government intervention, shocks cause temporary deviations, but the economy’s self-correcting mechanisms restore output and unemployment to natural levels while the price level adjusts permanently. This reflects classic long-run macroeconomic theory.
