THE EQUATION OF EXCHANGE—WHAT IS THE CURRENT VELOCITY OF MONEY? In the equation of exchange, MV = PQ, the velocity of money, V, is found by dividing nominal GDP (= PQ) by M , the money supply. Calculate the velocity of money for the past 4 years. How stable was V during that period? Is V increasing or decreasing?
