The study set out to investigate empirically the behaviour income velocity in Tanzania. The model used, which incorporate the demand for money hypotheses, was estimated for four definitions of velocity, namely the income velocity of currency in circulation (V0), narrow money (V1), the broad money (V2) and the extended broad money (V3) by using the Ordinary Least Squares (OLS) three sub-periods: 1967-1982, 1983-94 and the entire period from 1967-94. The descriptive results revealed four aspects: the behaviour of the income velocity was had phases: a continuous fall in the period from 1967-78; a 'puzzling trough' in the 1979-85 period; and a cyclical pattern in the rest of the sample period. Generally, the descriptive results suggested the income velocity in Tanzania exhibited a falling pattern in the 1967-1994 period. The Econometric results were not completely conclusive on the secular behaviour of the velocity, the opportunity cost of holding money, rate of monetization, and financial development. The evidence casts doubt on the reliability of the income velocity as an input for the formulation of monetary policy in Tanzania.
