4. Answer to 1. (d)(i) and (ii) The Fed will buy bonds which will increase the MS [from MS 1 to MS 2 ] and decrease the nominal interest rate. Answer to 1. (d)(iii) The lower nominal interest rate would increase quantity of investment The lower nominal interest rate would increase quantity of investment demanded by businesses [would also increase consumption and Xn] which would increase AD. The increase in AD would increase price level.

5. 1.(e) Now assume instead that the government and the Fed take no policy action in response to the recession. short-run AS (i) In the long run, will the short-run AS increase, decrease, or remain unchanged? Explain. natural rate of unemployment (ii) In the long run, what will happen to the natural rate of unemployment? Answer to 1. (e) (i) In the long run, prices would come down, and workers would accept lower wages, decreasing resource cost to businesses, and they would hire more workers as the SRAS curve would increase. Answer to 1. (e)( ii) With the SRAS curve shifting back to the right, this would bring the economy back to equilibrium at the natural rate of employment. Because we are back to the natural rate of unemployment, it did not change in the long run.

Japan, the European Union, Canada, and Mexico have flexible exchange rates. Japan attracts an increased amount of investment from the EU (a) Suppose Japan attracts an increased amount of investment from the EU. loanable funds market in Japan real interest rate in Japan (i) Using a correctly labeled graph of the loanable funds market in Japan, show the effect of the increase in foreign investment on the real interest rate in Japan. employment level in Japan in the short run (ii) How will the real interest rate change in Japan that you identified in part (a)(i) affect the employment level in Japan in the short run? Explain. Answer to 2. (a) (i) & (ii) (i) As can be seen on the graph, the increased investment in Japan would result in more yen in Japan’s depository institutions, and increasing the supply of LF in Japan and decreasing the real interest rate. (ii) With the RIR decreasing in Japan, there will be more investment [ a component of AD]which would increase AD and GDP, therefore increasing employment in the short run.

Dollar and appreciates that currency. Answer to 2. (b)(ii) The stronger Canadian dollar would make Canadian exports more expensive to Mexico, therefore decreasing Canadian exports to Mexico.

8. 3. Sewell Bank has the simplified balance sheet below. required reserve ratio (a) Based on Sewell Bank’s balance sheet, calculate the required reserve ratio. Answer to 3. (a) The Fed’s RR would be 20% as DD is $10,000 and RR is $2,000 and excess reserves are $0. (b) Suppose that the Fed purchases $5,000 worth of bonds from Sewell Bank. change in the dollar value of each What will be the change in the dollar value of each of the following immediately after the purchase? (i) Excess reserves (ii) Demand deposit ER would be $5,000 as any loan from the Fed is ER. DD would not immediately increase as any money from the Fed is all ER.

9. 3. [continued] MS can change 3. (c) Calculate the maximum amount that the MS can change as a result of the $5,000 purchase of bonds by the Fed.. Answer to 3. (c) The Total Money Supply could potentially change to $25,000. All of the $5,000 is ER for Sewell Bank so with a RR of 20% and a M M of 5, $5,000 x 5 = TMS of $25,000.

10. 3. [continued] price of bonds 3. (d) When the Fed purchases bonds, what will happen to the price of bonds in the open market? Explain. Answer to 3.

What is the effect of the cash deposit on the M1 measure immediate effect of the cash deposit on the M1 measure of the MS? Answer to 3. (e) No impact. It stays the same although it changes composition from $5,000 currency to $5,000 DD.
