cr + 1 ) / ( cr + rr

111
Q

money supply is ____________ to the monetary base

Thus, an increase in the monetary base does what to the money supply?

A

The money supply is proportional to the monetary base. Thus, an increase in the monetary base increases the money supply by the same percentage

112
Q

the ______ the reserve-deposit ratio, the _____ loans banks make, and the _____ money banks create from every dollar of reserves

Thus, a ____________ in the reserve deposit ratio raises the money multiplier and the money supply

A

the lower the reserve deposit ratio, the more loans banks make, and the more money banks create from every dollar of reserves.

thus a decrease in the reserve deposit ratio raises the money multiplier and the money supply

113
Q

the ___________ the currency-deposit ratio, the ________ dollars of the monetary base the the public holds as currency, the _________ base dollars banks hold as reserves, and _______ money banks can create

thus, a decrease in the currency deposit ratio ________ the money multiplier and the money supply

A

the lower the currency-deposit ratio, the fewer dollars of the monetary base the the public holds as currency, the more base dollars banks hold as reserves, and more money banks can create

RAISES

114
Q

a deduction in the discount rate does what to the money supply?

it raises the monetary supply, because more banks borrow at the Fed’s discount window

115
Q

an increase in the reserve requirements tend to do what to the reserve deposit ratio and thus do what to the money supply?

A

an increase in reserve requirements tends to raise the reserve deposit ratio and thus lower the money multiplier and the money supply
