4. Refer to Table 16. 2 and assume that the Fed's reserve ratio is 10 percent and the economy is in a severe recession. Also sup pose that the commercial banks are hoarding all excess reserves (not lending them out) because of their fear of loan defaults. Finally suppose that the Fed is highly concerned that the banks will suddenly lend out these excess reserves and possibly con tribute to inflation once the economy begins to recover and confidence is restored. By how many percentage points would the Fed need to increase the reserve ratio to eliminate one -third of the excess reserves? What would be the size of the monetary multiplier before and after the change in the reserve ratio ? By how much would the lending potential of the banks decline as a result of the increase in the reserve ratio ? L016. 3
