1. Explaining short-run economic fluctuations
Most economists believe that real economic variables and nominal economic variables behave independently of each other in the long run.
For example, an increase in the money supply, a
no long-run effect on the quantity of goods and services the economy can produce, a
and nominal variables is known as
F2
In the short run, however, most economists believe that real and nominal variables are intertwined. Economists use the model of aggregate demand
and aggregate supply to examine the economy's short-run fluctuations around the long-run output level. The following graph shows an incomplete
short-run aggregate demand (AD) and aggregate supply (AS) diagram-it needs appropriate labels for the axes and curves. You will identify some of
the missing labels in the questions that follow.
