单项选择题
Which of the following is the most accurate definition of the velocity of money The velocity of money is the:（）
A. GDP of a country divided by its price level.
B. money supply of a country divided by its price level.
C. GDP of a country divided by its money supply.
答案
参考答案：C
解析：
Velocity is the average number of times per year each dollar is used to buy goods and services (velocity = GDP/money). Therefore, the money supply multiplied by velocity must equal nominal GDP. The equation of exchange must hold with velocity defined in this way. Letting money supply = M, velocity = V, price = P, and real output = Y, the equation of exchange may be symbolically expressed as : MV = PY.
