Consider an economy with $12 billion in base money and a multiplier of 6. The money supply is currently $12 billion × 6 = $72 billion. Now let's say that the amount of base money increases by 50 percent, to $18 billion. How must the multiplier change for the money supply to remain unaffected by this change in base money? Instructions: Round your answer to two decimal places. The multiplier must change to: |

Show the impact of the increase in government purchases on the interest rate by shifting one or both of the curves on the following graph. INTEREST RATE 12 10 8 2 0 0 20 Money Supply known as the Money Demand 40 60 80 MONEY (Billions of dollars) 100 120 = Money Demand Money Supply ? Suppose that for every increase in the interest rate of one percentage point, the level of investment spending declines by $0.5 billion. Based on the changes made to the money market in the previous scenario, the new interest rate causes the level of investment spending to by Taking the multiplier effect into account, the change in investment spending will cause the quantity of output demanded to by at every price level. The impact of an increase in government purchases on the interest rate and the level of investment spending is effect. Use the purple line (diamond symbol) on the graph at the beginning of this problem to show the aggregate demand curve (AD3) after accounting for the impact of the increase…

Fill in the Value of Money column in the following table. Quantity of Money Demanded (Billions of dollars) Price Level (P) Value of Money (1/P) 1.00 1.5 1.33 2.0 2.00 3.5 4.00 7.0 Now consider the relationship between the price level and the quantity of money that people demand. The lower the price level, the money the typical transaction requires, and the money people will wish to hold in the form of currency or demand deposits. Assume that the Fed initially fixes the quantity of money supplied at $3.5 billion. Use the orange line (square symbol) to plot the initial money supply (MS,) set by the Fed. Then, referring to the previous table, use the blue connected points (circle symbol) to graph the money demand curve.

Suppose there is some hypothetical economy in which households spend $0.50 of each additional dollar they earn and save the $0.50 they have left over. The following graph plots the economy's initial aggregate demand curve (AD₂). Suppose now that the government increases its purchases by $3.5 billion. Use the green line (triangle symbol) on the following graph to show the aggregate demand curve (AD₂) after the multiplier effect takes place. Hint: Be sure the new aggregate demand curve (AD₂) is parallel to AD₁. You can see the slope of AD₁ by selecting it on the following graph. ?

Suppose that the central bank wants to stimulate the economy by increasing the money supply. The bankers estimate that the velocity of money is 3.3 and that the price level will increase from 120 to 128 due to the stimulus. Using the quantity equation of money, what will be the increment of a $320 billion dollar increase in the money supply on the quantity of goods (In Billions)and services in the economy given an initial money supply of $4.1 trillion? (Please round your answer to include 2 decimal places. Enter the ammoun in Billions, that is, If the total quantity decreases by 1 billion, enter your answer as -1.)

The following graph shows the money market in equilibrium at an interest rate of 7.5% and a quantity of money equal to $60 billion. Show the impact of the increase in government purchases on the interest rate by shifting one or both of the curves on the following graph. 15.0 Money Supply Money Demand 0 Money Supply 12.5 10.0 INTEREST RATE 5 5.0 25 0 0 20 Money Demand 40 60 80 100 MONEY (Billions of dollars) 120

1.25 MS, 1.00 Money Demand 0.75 MS2 0.50 0.25 3 4 QUANTITY OF MONEY (Billions of dollars) , therefore the equilibrium price level is According to your graph, the equilibrium value of money is Now, suppose that the Fed increases the money supply from the initial level of $2.5 billion to $4 billion. In order to increase the money supply, the Fed can use open market operations to the public. Use the purple line (diamond symbol) to plot the new money supply ( MS2 ). Immediately after the Fed changes the money supply from its initial equilibrium level, the quantity of money supplied is than the quantity of money demanded at the initial equilibrium. This expansion in the money supply will people's demand for goods and services. In the long run, since the economy's ability to produce goods and services has not changed, the prices of goods and services will and the value of money will VALUE OF MONEY

1. Suppose that the economy has the following money supply and demand equations: Money Supply: M = 8000Money Demand: M= 10,000 – 40,000rwhere money is in billions of dollars and interest rates, r , is written as a decimal(e.g., an interest rate of 10% would be written as .1 in the equation).A. Determine the equilibrium interest rate and quantity of money.B. What will happen in the money market if the interest rate is currently 10%?What is the amount of excess supply of or excess demand for money?C. Show in graph that at this interest rate (10%) there is disequilibrium in themoney market.

Suppose the money market for some hypothetical economy is given by the following graph, which plots the money demand and money supply curves. Assume the central bank in this economy (the Fed) fixes the quantity of money supplied. Suppose the price level decreases from 150 to 125. Shift the appropriate curve on the graph to show the impact of a decrease in the overall price level on the market for money. ?

Q8 Which of the following statements is consistent with a given (i.e., fixed) IS curve? Select one: a. A reduction in the interest rate causes money demand to decrease. b. A reduction in the interest rate causes investment spending to increase. c. An increase in government spending causes an increase in demand for goods. d. A reduction in the interest rate causes an increase in the money supply.
