2017 AP Macroeconomics FRQ #2

(A) Draw a CLG of the money market and show the effect of the reduced holdings of money on the equilibrium nominal interest rate in the short-run.

Money Market = Monetary Policy
Reduced holdings of money = Demand for Money decreases

From the Monetary Policy cheat sheet here

 Demand for Money falls, the Nominal Interest Rate (NIR) falls The opportunity cost of holding cash has fallen.

(B) Based on the changes in the interest rate in part (A), what will happen to each of the following in the short-run?
(i) Prices of previously issued Bonds. ((Bond Prices will Increase)

MR. Waugh - If interest rates are falling then we must assume that the interest rates of previous bonds must be higher.

Jung Sub - What does that mean, Mr. Waugh?

Mr. Waugh - Well Jung Sub, each bond has an amount of interest that it pays to the owner of the bond every year. It could pay 5% of the face value to the owner every year. Bond holders are rational people. If the banks are only paying 1% to borrow your money a bond holder would be making a profit by having a bond paying 5%.

So, if the nominal interest rate falls to 1%, then the price of a bond paying 5% will increase as it is now a better value than bonds created and sold today with a yield rate of 1%.

Is that clear Jung Sub?

Jung Sub -  Not really Mr. Waugh, but I think we should move on.

(ii) The price level and real income.

Cause and effect - If the nominal interest rate falls then consumption increases which drives up AD and therefore the PL and causes the RGDP to increase which implies that real income (Y) increases also.

Answer - PL and Y (incomes) increase

(C) With a constant money supply, based on your answer in part (B)(ii), will the velocity of money increase, decrease, remain unchanged or will it be indeterminate?

Velocity of money is the rate that money exchanges for goods and services. If incomes are increasing we would expect that the velocity of money would increase.

AD is increasing along with RGDP and (Y) incomes so people are spending money faster than before. Velocity has increased.

(D) If the FED (central bank) wishes to reverse the changes in the interest rate identified in part (A), what open market operation (OMO) would it use?

If interest rates are falling (part A), then the FED would sell bonds, reducing the money supply and increasing the Nominal Interest Rate.
