When the price level rises unexpectedly, some businesses may mistake part of the increase for an increase in the price of their product relative to others and so decrease their production.

The only way to rationalize an upward slope for the short-run aggregate supply curve is to argue that wages are sticky in the short run.

Study Notes
Macroeconomic Theories and Concepts
- Changes in the money supply primarily affect nominal variables, with no impact on real variables in the long run.
- An inverse relationship exists between output and unemployment; as output increases, unemployment decreases.
- Real values of wages, incomes, and interest rates are more significant than their nominal counterparts.
Aggregate Demand
- The aggregate-demand curve illustrates the total demand for domestic goods and services at various price levels.
- The model of aggregate demand and supply is crucial for understanding short-run economic fluctuations and the transition to long-run equilibrium.
- A downward-sloping aggregate demand curve indicates that higher price levels lead to decreases in consumption, investment, and net exports.
Money Supply Effects
- Increases in the money supply lower interest rates, promoting investment and shifting aggregate demand to the right.
- Conversely, a decrease in the money supply raises interest rates, resulting in reduced investment.
Long-Run Dynamics
- Technological advancements shift the long-run aggregate supply curve to the right, indicating growth in productive capacity.
- The long-run aggregate supply is vertical as price levels do not influence the long-term determinants of real GDP.
- Price level rises do not affect the position of the short-run aggregate-supply curve; however, anticipated price increases can shift it left.
Short-Run Aggregate Supply (SRAS)
- The upward slope of the short-run aggregate supply curve is justified by the assumption that actual prices exceeding expected prices lead to increased output.
- Real GDP fluctuations stem from both aggregate demand and aggregate supply shifts, not solely demand changes.
Aggregate Demand Shifts and Economic Outlook
- Increased uncertainty or pessimism about the economy prompts firms to reduce investment, shifting aggregate demand left.
- Optimism about future economic conditions results in rising prices and decreased unemployment in the short run.
- Following a rightward shift in aggregate demand, rising price level expectations can lead to a leftward shift in the short-run aggregate-supply curve.
Long-Run Aggregate Demand Implications
- In the long run, heightened aggregate demand raises the price level without altering real GDP.
- Policymakers can influence aggregate demand, helping to lessen the impact of economic fluctuations.
Economic Phenomena and Misconceptions
- Stagflation is not the result of continuous declines in aggregate demand.
- The aggregate demand and supply model's primary purpose is not the demonstration of the classical dichotomy.
- If a central bank increases the money supply in response to short-run aggregate supply reductions, it may restore unemployment levels but also amplify price increases.
