Money Multiplier

M = m MB

Deriving Money Multiplier

R = RR + ER

RR = rD D

R = (rD D) + ER

Adding C to both sides

R + C = MB = (rD D) + ER + C

1. Tells us amount of MB needed support D, ER and C

2. $1 of MB in ER, not support D or C

MB = (rDD) +({ER/D}D )+ ({C/D}D)

= (rD + {ER/D} + {C/D}) D

1D = MB

rD + {ER/D} + {C/D}

M = D + ({C/D} D ) = (1 + {C/D}) D

1 + {C/D}M = MB

rD + {ER/D} + {C/D}

1 + {C/D}m =

rD + {ER/D} + {C/D}

m < 1/rD because no multiple expansion for currency and because as D ER

Full Model

M = m (MBn + DL)
