The paper investigates the linkages between temperature anomalies, radiative forcing and ENSO. By means of a new flexible trend modeling approach, we uncover a nonlinear linkage between radiative forcing and global temperature anomalies. The nonlinear trend closely tracks the low frequency...

A new noise filtering approach, based on flexible least squares (FLS) estimation of an unobserved component local level model, is introduced. The proposed FLS filter has been found to perform well in Monte Carlo analysis, independently of the persistence properties of the data and the size of...

In this paper a new approach to factor vector autoregressive estimation, based on Stock and Watson (2005), is introduced. In addition to sharing all the relevant features of the Stock and Watson (2005) approach, in its static formulation, the proposed method has the advantage of allowing for a...

A new approach to the modelling of common components in long memory processes is introduced. The approach is based on a two-step procedure relying on Fourier transform methods (first step) and principal components analysis (second step). Differently from other available methods, it allows the...

In this paper the long-run trend in RPI inflation (core inflation) for the UK over the 1961-1997 period is estimated within the framework of a multivariate common trends model which extends the bivariate VAR approach of Quah and Vahey (1995). In this context core inflation is directly linked to...
