答案 AVelocity is the average number of times per year each dollar is used to buy goods and services (velocity = nominal 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.
