This paper introduces a new decomposition of euro area headline inflation into core, cyclical, and residual components. Our new core inflation measure, the structural core inflation rate, is the expected headline inflation, conditional to medium to long-term demand and supply-side developments....

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...

Many previous analyses of inflation have used either long memory or nonlinear time series models. This paper suggests a simple adaptive modification of the basic ARFIMA model, which uses a flexible Fourier form to allow for a time varying intercept. Simulation evidence suggests that the model...
