1. (a.) Third National Bank is fully loaned up with reserves of $20,000 and demand deposits equal to $100,000. The reserve ratio is 20%. Households deposit $5,000 in currency into the bank. How much excess reserves does the bank now have, and what is the maximum amount of new money that can be created in the banking system as a result of this deposit? Show all work.

(b.) What is the discount rate in the banking system? Explain how the Fed manipulates this rate to achieve macroeconomic objectives.

2. Let the exchange rate be defined as the number of dollars per British pound. Assume there is a relatively lower rate of inflation in U.S. relative to that of Britain.

(a.) Would this event cause the demand for the dollar to increase or decrease relative to the demand for the pound? Why?

(b.) Has the dollar appreciated or depreciated in value relative to the pound?

(c.) Does this change in the value of the dollar make imports cheaper or more expensive for Americans? Are American exports cheaper or more expensive for importers of U.S. goods in Great Britain? Illustrate by showing the price of a U.S. cell phone in Britain,before and after the change in the exchange rate.

(d.) If you had a business exporting goods to Britain, and U.S. inflation fell as discussed above in this example, would you plan to expand production or cut back? Why?
