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 the paper we propose a new methodological approach to core inflation estimation, based on a frequency domain principal components estimator, suited to estimate systems of fractionally cointegrated processes. The proposed core inflation measure is the scaled common persistent factor in...

In this paper we introduce a new common long memory factor model. The model allows to estimate the common persistent component in fractionally cointegrated processes. We find evidence of cobreaking and fractional cointegration in excess nominal money growth and inflation in the euro area, and...

In the paper we propose a new methodological approach to core inflation estimation, based on a frequency domain principal components estimator, suited to estimate systems of fractionally cointegrated processes. The proposed core inflation measure is the common persistent feature in inflation and...

In this paper we test for the existence of long memory and structural breaks in the realized variance process for the DM/US$ and Yen/US$ exchange rates. While long memory is evident in the actual processes, a structural break analysis reveals that this feature is partially explained by...

In this paper we investigate the long-run link between inflation and money growth in the US since 1960. A measure of the long-run inflation trend is constructed, which bears the interpretation of monetary inflation rate and is directly related to the excess nominal money growth process (money...

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...
