Chapter 18 Flashcards
Define excess reserve ratio (little e)
e = ER/DD
Define little c
c = Currency/DD
Define “rr”
rr = reserve requirement on DD
Given: find c, e, MS and m Currency = 400 DD = 800 ER = .8 rr = .1 or 10%
c = C/DD = 400/800 = .5
e = ER/DD = .8/800 = .001
MS = Currency + DD = 400+800=1,200
Complete Money Multiplier m = (1+c/rr+c+e) = (1+.5/.10+.5+.001) ~ 2.5
Monetary Base (MB)
MB = Currency + ALL Reserves (RR and ER)
Complete Money Multiplier
MS = [(1+c)/(rr+c+e)]MB
Money Supply (MS)
MS = Currency + DD
Money Multiplier (m)
m = (1 + c)/(rr + c + e)
Relate MS to the MB algebraically
MS = (m)MB
*This is the check, to make sure MS is really equal to (m)x(MB)
Do the money multiplier problem
It’s on the notes worksheet and in the Ch. 18 notes in binder.
How can c (and therefore probably C) rise with an unchanged MB?
DD must fall enough that the existing monetary base is sufficient to support banks’ reserve needs.
