If velocity (V) and aggregate output (Y) remain constant at $4 and $1,250 billion, respectively, what happens to the price level (P) if the money supply (M) declines from $475 billion to $375 billion?
The equation of exchange is
MV=PY
M=475
V=4
Y=1250
P=?
P=MV/Y
P=(475*4)/1250
=1.52
the price level is 1.52
and the M changes to 375
P=(375*4)/1250
=1.2
The price level changes from 1.52 to 1.2.
