Forecasting inflation is an important and challenging task. In this paper we assume that the core inflation components evolve as a multivariate local level process. This model, which is theoretically attractive for modelling inflation dynamics, has been used only to a limited extent to date...

In the paper we propose a new methodological approach to core in- flation 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 study the zero frequency spectral properties of fractionally cointegrated long memory processes and introduce a new frequency domain principal components estimator of the cointegration space and the factor loading matrix for the long memory factors. We find that for fractionally...

Using a common trends model, we estimate a forward-looking core inflation measure for the Euro area based on long-run relations among major macroeconomic variables, bearing the interpretation of long-run inflation forecast. The proposed measure may be particularly suitable for the two-pillar...

This study contributes to the investigation of the macro- finance interface by assessing the economic content and risk based interpretation of widely employed risk factors in the specifi cation of empirical asset pricing models, i.e., Fama-French size and value, and Carhart momentum factors, as...

We use high frequency data for the mark/dollar exchange rate for the period 1992-1995 to evaluate the effects of interventions. We estimate an unobserved components model that decomposes volatility into non-stationary and stationary parts. Stationary components in turn are decomposed into...

In this paper we show how IGARCH effects can arise as an artifact of unaccounted structural change. Using daily returns for the DM/US$ and Yen/US$ exchange rates, the finding is shown to have empirical relevance. GARCH models appear to be useful approximations, for short term forecasting, to a...

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...
