Aggregate output
Determine whether each of the following would cause a shift of the aggregate demand curve, a shift of the aggregate supply curve, a shift in neither curve, or a shift in both curves. If a shift is caused, indicate which curve shifts, and in which direction it shifts. What happens to aggregate output and the price level in each case?
The price level changes.
Consumer confidence increases.
The supply of resources decreases.
The wage rate decreases.
Sample Answer
- The price level changes. This does not cause a shift in either the aggregate demand curve or the aggregate supply curve. The price level is on the vertical axis of the aggregate demand/aggregate supply graph, so it is a parameter of the model, not a variable that is determined by the model.
