Suppose we have the following banking data (in \$billion): C=$300 Currency in circulation D=$2,000 Demand deposits rr=0.10 Required reserve ratio ER=$1,340 Excess reserves in the banking system There are no other types of deposits in the banking system. Calculate for us the following: Currency-deposit ratio (c)= Excess-Reserves-deposit ratio (er)= Money supply = \$billion Monetary base = \$billion
