Due to presence of HOMEWORKLIB POLICY, I am answering first question.
1.
Ans: c. fall.
Explanation:
Since quantity of money demanded is less than quantity of money supplied, we have following situation:

With current rate being higher than equilibrium rate, people will invest money and purchase more bonds due to which their return (interest) will fall. The excess demand of bonds will result in fall in interest rate in the market.
Equilibrium rate = i*
If you are satisfied with the answer, please provide a positive rating. Feel free to comment in case of queries.
Have a nice day ahead!
If the quantity of money demanded is $100 billion and the quantity of money supplied is...

If at some specific interest rate the quantity of money demanded is less than the quantity of money supplied, people will desire to buy interest-earning assets causing the interest rate to decrease. Select one: True False In recent years, the Fed has conducted policy by setting a target for the federal funds rate. Select one: True False A decrease in taxes is an expansionary fiscal policy designed to increase aggregate demand and reduce unemployment. Select one: True False If aggregate...

In the long run, an increase in the money supply growth rate? A.reduces expected inflation so the short run Philips curve shifts left B. raises expected inflation so the short-run phillips curve shifts left C.raises expected inflation so the short-run phillips curve shifts right d. none of the above is correct
An increase in expected inflation shifts the short-run Phillips curve right. a. b. short-run Phillips curve left. long-run Phillips curve right. C. d. long-run Phillips curve left. O Icon Key
Illustrate and briefly explain the beginning of a demand-pull inflation. 3. When answering parts a and b, draw the relevant Phillips curve. Using a short-run Phillips curve, what is the effect on the unemployment rate if the inflation rate unexpectedly rises. Using a long-run Phillips curve, what is the effect on the unemployment rate if the inflation rate rises and people expect the rise. Explain how your answer to part a about the unexpected rise in the inflation rate changes in...
11. How does a decrease in the expected rate of inflation shift the Phillips curves? a. It shifts both the short-run and long-run Phillips curves to the right. b. It shifts both the short-run and long-run Phillips curves to the left. It shifts only the short-run Phillips curve to the right. d. It shifts only the short-run Phillips curve to the left. in hou do the short-run Phillips curve and unemplo C.
The Economy in 2008 In the first half of June 2008 the effects of a housing and financial crisis and an increase in world prices of oil and foodstuffs were affecting the economy. Refer to The Economy in 2008. The effects of the housing and financial crises could be shown by shifting a. aggregate demand to the right. b. aggregate demand to the left. c. aggregate supply to the left. d. aggregate supply to the right. There is a temporary...
6) Let’s try to understand the long-run and short-run implications of monetary policy issues. Let’s assume inflation is currently 2% and that monetary policy has an inflation targeting rule that makes desired (targeted) inflation also 2%. Finally suppose the equilibrium real interest rate in the economy is 1% and that “beta” in the Phillips curve is 1.2. a) In the long-run, the output gap should be 0% and there should be no shocks to inflation. In that situation what will...
