Question

Suppose the economy is in long-run equilibrium. In a short span of time, there is a sharp rise in the stock market, an increase in government purchases, an increase in the money supply and a decline in the value of the dollar. In the short run a. the price level and real GDP will both rise. b. the price level and real GDP will both fall. c. neither the price leave nor real GDP will change. d. All of the above are possible.

Answer 1

All of the above are possible.

Step-by-step explanation:

Discussions here center on equilibrium of an economy in a long run, and here after the government activities, their is a decline in dollar value; therefore in the short run, the price level and real GDP will both rise in as much as the price level and real GDP will also both fall. It is also gathered that neither the price leave nor real GDP will change.

The transition from the short run to the long run may be done by considering some short run equilibrium that is also a long run equilibrium as to supply and demand, then comparing that state against a new short run and long run equilibrium state from a change that disturbs equilibrium, say in the sales tax rate, tracing out the short run adjustment first, then the long run adjustment.
