Refer to the sets of the aggregate demand, short-run aggregate supply, and long-run aggregate supply curves. Use the graphs to explain the process and steps by which each of the following economic scenarios will shift the economy from one long-run macroeconomic equilibrium to another equilibrium. Under each scenario, elaborate the short-run and long-run effects of the shifts in the aggregate demand and aggregate supply curves on the aggregate price level and aggregate output (real GDP).

a. Suppose the household wealth decreases due to a decline in the stock market asset prices.

b. Assume the government lowers taxes, which increases the household’s disposable income. However, the government purchases (spending) remains the same.

2. Suppose the economy of a hypothetical country has reached its long-run macroeconomic equilibrium when each of the following aggregate demand shocks occurs. What kind of gap, inflationary or recessionary gap, will the economy face after the AD shock indicated by the shift in AD curves? What types of fiscal policy instruments will help move the economy back to the potential level of output (real GDP)? Give specific examples.

a. At the long-run macroeconomic equilibrium, the stock market boom occurs and this increases the value of stocks households hold.

b. The government increases its purchases (spending) due to natural disasters.

c. Assume the Central Bank reduces the money supply in the economy which leads to an increase in the interest rates.

Macroeconomic stability and growth are fundamentally driven by the shifts in aggregate demand (AD), short-run aggregate supply (SRAS), and long-run aggregate supply (LRAS). These curves depict the overall economic activity, and their movements reflect changes in economic conditions, policies, or external shocks. Understanding how these shifts influence the economy's equilibrium is essential for policymakers aiming to stabilize prices and maximize output.

In the first scenario, a decline in household wealth due to decreased stock market asset values causes a fall in consumer confidence and spending. On the aggregate demand curve, this manifests as a leftward shift, representing a decrease in overall spending within the economy. The immediate effect is a reduction in real GDP and a decline in the aggregate price level, signaling a recessionary gap. In the short run, firms respond to decreased demand by reducing production, which further depresses prices and output. Over the longer term, the economy may adjust through lower wages and prices, shifting SRAS rightward, partially offsetting the initial decline. Ultimately, the economy moves to a new equilibrium with lower output and prices, but if the drop in wealth persists, policymakers may need to intervene with expansionary measures.

Conversely, when the government reduces taxes, households have more disposable income, boosting consumption. This increase shifts the AD curve rightward, leading to higher output and prices in the short run, indicating a demand-pull inflation. The economy expands toward a new equilibrium, but if the economy is already at or near full employment, this can lead to an inflationary gap, necessitating measures to cool the economy if inflation becomes excessive.

The second set of scenarios involves shocks to aggregate demand and supply impacting macroeconomic gaps. A stock market boom elevates household wealth, shifting the AD curve rightward, resulting in an expansion above potential output, thus creating an inflationary gap. To address this, fiscal policy could include contractionary measures like increasing taxes or reducing government spending to shift AD leftward, returning output to potential and controlling inflation.

In contrast, increased government purchases following natural disasters provide a fiscal stimulus, shifting the AD curve rightward and possibly creating an inflationary gap if the economy surpasses its potential output. Policymakers might respond by tightening monetary policy—raising interest rates—or implementing tax increases to reduce aggregate demand, preventing inflationary pressures.

Finally, a reduction in the money supply by the Central Bank raises interest rates, discouraging borrowing and spending. The AD curve shifts leftward, leading to a recessionary gap characterized by lower output and prices. To counteract this, expansionary fiscal policy—such as increased government spending or tax cuts—can stimulate demand and help restore the economy to its natural level of output. These various policy tools serve to counteract the specific impacts of each shock, maintaining economic stability and growth.

Overall, understanding the interplay of demand and supply shocks with fiscal and monetary policy is crucial for managing economic fluctuations. Effective policy responses rely on accurately diagnosing the type of gap—whether inflationary or recessionary—and choosing appropriate measures to stabilize prices and maximize employment, sustaining long-term economic health.
