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...

The relationship between recessions and productivity has been the focus of an important body of theoretical and empirical research in the last two decades. We contribute to this literature by presenting new evidence on the evolution of productivity in the aftermath of recessions. Our method...

This note revisits the temporal causality between exchange rates and fundamentals put forward by Engel and West (2005). We analyze the causal link within multivariate VARs by making use of the concept of multi-step causality. Our results show that, considering information content beyond...
