This paper proposes a Bayesian approach to explore money-output
causality within a logistic smooth transition VECM framework. Our
empirical results provide substantial evidence that the postwar US
money-output relationship is nonlinear, with regime changes mainly
governed by the lagged inflation rates. More importantly, we obtain
strong support for long-run non-causality and nonlinear Grangercausality
from money to output. Furthermore, our impulse response
analysis reveals that a shock to money appears to have negative accumulative
impact on real output over the next fifty years, which calls
for more caution when using money as a policy instrument.
