Abstract: The determinants of money velocity are explored under various assumptions on interest rate uncertainty in a monetary general equilibrium model. It is found that the appearance of velocity function instability can be produced by overlooking interest rate stochastic volatility. In addition, when interest rates are subject to stochastic volatility, velocity is found to follow a nonlinear stochastic process. We conclude that the variances of interest rate stochastic processes are omitted variables in many studies of velocity function behavior.
