The rise in the interest rate from to creates a momentary excess supply of real U.S.
money balances at the prevailing price level . However, since under this.
Monetary Approach, prices are assumed to be flexible, prices will immediately adjust from
to , thus causing the following two effects: One, Reducing real money supply and two,
bringing U.S. money market back into equilibrium.
