Incorporating the Liquidity Preference Function into the Simple Model Changes

Multiple Choice

B) Changes in the inflation rate no longer affect nominal interest rates: the Fisher effect is no longer operative.
C) Changes in nominal interest rates have an immediate effect on the real exchange rate, bypassing the adjustment process.
D) Changes in the money growth rate increase real balances, since prices are no longer flexible.
