Suppose that a sudden increase in aggregate demand moves the economy from its long-run equilibrium. (a) Illustrate this change using the aggregate demand-aggregate supply model. (b) What are the effects of this change in the short run and the long run?

Answer #1

A sudden increase in aggregate demand from its long run equilibrium which is when output equals full employment level of output shifts to a higher output in the short run as in the long run the economy cannot exist at a output above full employment level except if there is a structural change and equilibrium output only changes. Otherwise, an increase in aggregate demand would lead to inflationary pressures as price levels rise. In the long run, firms would shorten production to discourage excess demand as output is already above potential level so more production is not possible.

Starting from long-run equilibrium, draw an aggregate demand-aggregate supply graph to illustrate the difference between a long-run and a short-run equilibrium due to an increase in aggregate demand. Once the economy is in the short-run equilibrium, explain and graphically illustrate how long-run equilibrium will be restored.

Suppose the economy is initially in long-run equilibrium. Then, suppose a new technology is introduced that boots productivity across key strategic sectors in the economy. According to the model of aggregate demand and aggregate supply, what happens to prices and output in the short run?                         a- Prices rise and output falls.                         b- Prices fall and output falls.                         c-Prices fall and output rises.                         d- Prices rise and output rises.
