Economic Consequences of Sudden Aggregate Demand Shock
Introduction
This paper discusses the economic consequences of a sudden Aggregate Demand (AD) shock, illustrating the implications on the economy using the Aggregate Demand and Aggregate Supply (AD-AS) model. The economy begins in long-run equilibrium, followed by the analysis of shifts in aggregate demand, changes in output and price levels, the transition to a new long-run equilibrium, and possible government or central bank actions in response. A thorough understanding of classical and Keynesian theories is essential for realizing the implications of such a demand shock on economic performance.
1. Initial Equilibrium
In a long-run equilibrium, an economy operates at an output level (Y) that corresponds to the full employment of resources, represented by a vertical Long-Run Aggregate Supply (LRAS) curve. In this situation, the economy is at point A. The AD curve slopes downward due to the wealth effect, interest rate effect, and exchange rate effect (Blanchard, 2020). This initial state can be illustrated with the pricing level (P) intersecting the AD curve, Short-Run Aggregate Supply (SRAS), and LRAS.
2. Sudden Aggregate Demand Shock
A sudden aggregate demand shock can arise from various factors, such as changes in consumer confidence, government spending, fiscal stimulus, or monetary policy (Mankiw, 2018). For this presentation, we will explore the scenario of increased government spending following a rise in consumer confidence. This increase in consumption and investment causes the AD curve to shift rightward from AD1 to AD2.
3. Short-Run Effects
As aggregate demand increases, the economy moves from point A to point B on the AD-AS graph. The increase in AD leads to a higher output level (Y2) and price level (P2). The SRAS curve remains constant at this stage. In this short-run scenario, businesses respond to increased demand by ramping up production, resulting in higher employment levels (Friedman, 1968). Thus, short-run effects entail:
- An increase in real GDP from Y1 to Y2.
- An increase in the price level from P1 to P2.
This output increase may create inflationary pressure due to demand-pull inflation, characterized by rising prices driven by increased consumer spending (Samuelson & Nordhaus, 2010).
4. Transition to New Long-Run Equilibrium
In the long run, the economy must adjust to the initial shock. As output exceeds potential GDP, resource utilization increases, leading to upward pressure on wages and costs (Mankiw, 2018). Over time, the SRAS curve will begin to shift leftward from SRAS1 to SRAS2 due to increasing production costs and wages, moving the economy toward a new long-run equilibrium at point C.
At point C:
- The economy stabilizes at a higher price level (P3) than before the shock (P1), but real output returns to potential GDP (Y1).
- This adjustment reflects the natural self-correction mechanism described by Keynesian economics (Blanchard, 2020).
The transition from point B (short-run equilibrium) back to point C (long-run equilibrium) underscores how economies self-correct after demand shocks, typically resulting in inflation.
5. Possible Government or Central Bank Actions
In response to a sudden AD shock, policymakers may consider monetary and fiscal interventions to stabilize the economy. For instance:
- Monetary Policy: The central bank may opt to hike interest rates to control inflation and reduce aggregate demand. This would shift the AD curve back to the left.
- Fiscal Policy: The government might reduce spending or increase taxes to decrease disposable income, which would decrease consumption and thus aggregate demand.
For this analysis, let us explore the implementation of monetary policy where the central bank decides to raise interest rates from i1 to i2. As interest rates increase, borrowing becomes more expensive, leading to reduced consumer spending and business investment, causing the AD curve to shift back left from AD2 to AD3.
The economy then moves from point C (new long-run equilibrium) back to a stable equilibrium point D, where the price level decreases to P4 and the output stabilizes at the potential GDP (Y1).
6. Conclusion
The analysis showcases the impactful consequences of sudden aggregate demand shocks on an economy. Initially, an AD shock results in higher output and price levels, leading to inflationary pressures. However, over the long run, the economy self-corrects back to potential output, albeit at a higher price level. Policymakers, especially central banks, play a critical role in managing these shocks through monetary policy adjustments to ensure economic stability. Understanding these dynamics is crucial for effective macroeconomic management.
