Macroeconomics in global context
1. For this question use the following assumptions. The commercial banking system has a target reserve ratio of 5 percent and there is no cash drain. A new immigrant to the country makes a cash deposit of \$1,000. In the following table show how deposits, reserves, and loans change as the new deposit permits the banks to “create” money.
Round ? Deposits ? Reserves ? Loans
First
Second
Third
Fourth
Fifth

a. Complete the entire table.
b. You have now completed the first five rounds of the deposit-creation process. What is the total change in deposits so far as a result of the single new deposit of \$1000?
c. This deposit-creation process will go on forever, but it will have a finite sum. In the text, we showed that the eventual total change in deposits is equal to 1/v times the new deposit, where v is the target reserve ratio. What is the eventual total change in deposits in this case?
d. What is the eventual total change in reserves? What is the eventual change in loans?

2) The diagram below shows the demand for money and the supply of money.
a. Explain why the Money Demand Curve is a downward sloping curve.
b. Suppose the interest rate is at iA. Explain how firms and households attempt to satisfy their excess demand for money. What is the effect of their actions?
c. Suppose the interest rate is at iB. Explain how firms and households attempt to dispose of their excess supply of money. What is the effect of their actions?

Now suppose there is an increase in the transactions demand for money because of growth in real GDP. Beginning at i*, explain what happens in the money market. How is this shown in the diagram?
