What are the three steps to analyze a shift in aggregate demand in the AD-AS model?
First, shift the aggregate demand curve; second, find the new short-run equilibrium; third, adjust the short-run aggregate supply to achieve a new long-run equilibrium.
What happens to the aggregate demand curve when investment spending decreases?
The aggregate demand curve shifts to the left, leading to lower price levels and GDP in the short run.
Which components make up aggregate demand?
Aggregate demand consists of consumption, investment, government purchases, and net exports.
What is the effect of a decrease in aggregate demand on short-run equilibrium price and GDP?
Both the price level and GDP decrease in the short-run equilibrium.
How does the short-run aggregate supply curve react to a leftward shift in aggregate demand?
The short-run aggregate supply curve shifts to the right to restore long-run equilibrium.
What is the result in the long run after a decrease in aggregate demand and subsequent supply adjustment?
The economy returns to its original long-run GDP but at a lower price level.
What causes demand-pull inflation in the AD-AS model?
An increase in aggregate demand, such as higher government spending, causes demand-pull inflation by raising prices.
What happens to the aggregate demand curve when government spending increases?
The aggregate demand curve shifts to the right, resulting in higher prices and GDP in the short run.
What is the effect of an increase in aggregate demand on short-run equilibrium GDP?
Short-run equilibrium GDP temporarily exceeds the long-run equilibrium GDP, reflecting a 'hot' economy.
How does the short-run aggregate supply curve react to a rightward shift in aggregate demand?
The short-run aggregate supply curve shifts to the left to return the economy to its long-run equilibrium.
After an increase in aggregate demand and supply adjustment, what happens to long-run equilibrium price and GDP?
Long-run equilibrium GDP returns to its original level, but the price level is higher.
Why does the short-run aggregate supply shift in the opposite direction of aggregate demand?
It shifts oppositely to restore the economy to its long-run equilibrium after a demand shock.
What is meant by 'temporary overshooting' of long-run GDP in the AD-AS model?
It refers to short-run GDP exceeding long-run equilibrium due to increased aggregate demand before supply adjusts.
What is the role of the long-run aggregate supply curve during shifts in aggregate demand?
The long-run aggregate supply curve remains constant, representing the economy's potential output.
What happens to price levels in the long run after a negative aggregate demand shock?
Price levels decrease in the long run, while GDP returns to its original equilibrium.
