Assume That All Banks Shown in the Table Below Observe

Assume that all banks shown in the table below observe the same required reserve ratio. Also assume that the banks are listed in sequential order (thus the loans from The First National Bank become the deposits for the Second National Bank, and the loans from the Second National Bank become the deposits for the Third National Bank, and so on). Also, the banks' balance sheets must always be balanced.

$\begin{array}{ll}\hline \text { ASSETS } & \text { LIABILITIES } \\\hline \text { Required reserves }\quad\$ 26,000& \text { Deposits }\quad \$ 520,000 \\\text { Loans } & \\\text { TOTAL } & \text { TOTAL }\end{array}$

$\begin{array}{ll}\text { Second National Bank } & \\\hline \text { ASSETS } & \text { LIABILITIES } \\\hline \text { Required reserves } & \text { Deposits } \\\text { Loans } & \\\text { TOTAL } & \text { TOTAL } \\\hline\end{array}$

$\text { Third National Bank }$
$\begin{array}{ll}\hline \text { ASSETS } & \text { LIABILITIES } \\\hline \text { Required reserves } & \text { Deposits } \\\text { Loans } & \\\text { TOTAL } & \text { TOTAL }\end{array}$
Use the information in the table to answer the following questions:
A) Fill in the balance sheets for all banks in the table.
B) What is the initial money multiplier in this country?
C) Now suppose that banks fear an increased demand for withdrawals so each bank maintains 3% extra deposits as excess reserves over and above required reserves. What is the effective money multiplier now?
D) What difficulty associated with monetary policy is illustrated by this question?
