CSSA allows to identify the association between the extracted component and the frequencies they represent without the intervention of the analyst. Another relevant characteristic is that CSSA produces strongly separable components, meaning that the resulting estimated signals are uncorrelated. In this contribution we deepen in the strong separability of CSSA and compare it to SSA by means of a detailed example. Finally, we apply CSSA to UK and US quarterly GDP to check that it produces reliable cycle estimators and strong separable components. We also test the absence of any seasonality in the seasonally adjusted time series estimated by CSSA.

However, parametric and non-parametric methods for signal extraction produce revisions at the end of the sample, and the arrival of new data makes it difficult to assess the state of the economy. In this paper, we compare two signal extraction procedures: Circulant Singular Spectral Analysis, CiSSA, a non-parametric technique in which we can extract components associated with desired frequencies, and a parametric method based on ARIMA modelling. Through a set of simulations, we show that the magnitude of the revisions produced by CiSSA converges to zero quicker, and it is smaller than that of the alternative procedure.

(1990). This original model, linear in its structure, incorporates oscillant dynamic relationships between the dependent and the explanatory variables. In the nonlinear model estimated in this paper, the response of the investment to production

(1990). Dicha estimación contiene filtros racionales con raíces complejas que producen respuestas oscilantes ante variaciones de tipo impulso sobre las variables explicativas. Se detecta que tal característica de los filtros se debe a que las oscilaciones en la inversión ocurridas en los
Inflation in the European Monetary Union is measured by the Ra.IlJllonised Consumer Price Index (... more Inflation in the European Monetary Union is measured by the Ra.IlJllonised Consumer Price Index (RCP!) and it can be analysed by breaking down the aggregate index in two different ways. One refers to the breakdown into price indexes corresponding to big groups of markets throughout the European countries and another considers the RCP! by countries. The paper shows that both

This paper considers factor models to produce a single forecast from several individual forecasts provided by the Survey of Professional Forecasters for the main US macroeconomic aggregates.

En este trabajo se comprueba cómo la inflación tendencial, que excluye del cómputo global los precios de los alimentos no elaborados, energía, grasas, tabaco y paquetes turísticos, también se ha reducido, tanto en bienes como en servicios. Los sectores con mayores tasas anuales y pesos en la inflación del componente de servicios resultan ser vivienda, restaurantes y hoteles, y transporte. También se estudia el diferencial de inflación entre España y la Unión Monetaria Europea en el sector servicios, que para vivienda es de 1,5 puntos porcentuales, para restaurantes y hoteles es de 2 puntos y para transportes se anuló en 1999 y luego ha repuntado ligeramente. La reducción de la inflación tendencial en servicios ha sido importante, pero insuficiente en comparación con otros países europeos. Además, el diferencial de inflación entre bienes y servicios es a...
