Answer:
Step-by-step explanation:
a. A temporary increase in government purchases would result in a reduction in savings, which would, in turn, lead to the implementation of higher taxes by the government so as to match prices and wages.
This would: make output to remain unchanged, real interest to increase and current price level to increase as well.
b. A reduction in expected inflation would lead to an increment in the demand for real money, as people do not expect inflation to increase for a while. Thus, more demand creates a reduction in the price level. Everything else remains unchanged. This would: make output remain unchanged, real interest remain unchanged and the current price level to decrease.
C. A temporary increase in labor supply would make more people have jobs and therefore more people can save. If more people save the interest rates are liable to decrease therefore money demand will increase. This would: make output to increase, real interest to decline and current price level to decrease.
d. An increase in the interest rate paid on money will lead to a higher demand for money. With an unchanged nominal money supply and higher money demand, the price would decline but everything remains unchanged. This would make: output remain unchanged, real interest remains unchanged and the current price level decrease.
