Calculate the money multiplier for the following values of the currency, excess reserves, and required reserves ratios (i.e., complete the following table) and explain why the money multiplier decreases when the currency or excess reserves ratio increase:

Currency deposit ratio 0.5 0.7 0.5 Excess reserves ratio 0.01 0.01 0.9 Required reserves ratio 0.08 0.08 0.08 Money multiplier
