In this paper we propose Granger (non-)causality tests based on a VAR model allowing for time-varying coefficients. The functional form of the time-varying coefficients is a Logistic Smooth Transition Autoregressive (LSTAR) model using time as the transition variable. The model allows for...

Over the last two centuries, the cross-spectral coherence between either narrow or broad money growth and inflation at the frequency ù=0 has exhibited little variationbeing, most of the time, close to onein the U.S., the U.K., and several other countries, thus implying that the fraction of...
