The US real GNP is analysed by means of fractionally integrated techniques. LM tests proposed by Robinson for testing unit roots and other fractionally integrated hypotheses are applied to the quarterly GNP series and to its log-transformation. The maximum likelihood estimation procedure of...

The order of integration of the industrial production index in the UK is investigated by means of semiparametric techniques in the time and in the frequency domain. Several methods like the R\S statistic, along with others proposed by Robinson in a number of articles are applied to various...

This study examines the stochastic properties of different measures of Total Factor Productivity (TFP) in the USA and their components using fractional integration. The results show that its structure is more complicated than expected, formed by the interaction of various seasonal and...

The annual structure of the real GDP in the UK, France, Germany and Italy is examined by means of fractionally integrated techniques. Using a version of a testing procedure due to Robinson (Journal of the American Statistical Association, 84, 1420-37, 1994), it is shown that the series can be...

The stochastic behaviour of the real interest rates in ten European countries, Canada and the US is examined in this article by means of fractionally integrated techniques. Using a procedure, specifically designed for testing I (d) statistical models, the results show that the real interest...

This article deals with the relationship between international trade and tourism. We focus on the effect that German tourism to Spain has on German imports of Spanish wine. Due to the different stochastic properties of the series under analysis, which display different orders of integration, a...

This article deals with the relationship between international travelling and trade. For this purpose we focus on a particular case study: the connection between the Spanish wine exports to Germany and the German travellers to Spain. Unlike previous studies we use a methodology based on...

Seasonal fractional models are shown in this article to be alternative credible ways of modelling the seasonal component in macroeconomic time series. A testing procedure that allows one to test different orders of integration at zero and at each of the seasonal frequencies is described. This...

This article examines the persistence of unemployment in the USA and four European countries by means of fractionally integrated ARMA (ARFIMA) models. In doing so, a type of flexibility in modelling low-frequency dynamics not achieved by non-fractionally ARIMA models can be provided. The results...

In this paper we first show that it is possible to modify linear real business cycle models to allow for disaggregate (industry-specific) factors in the generation of macroeconomic fluctuations. We then try to determine the relative importance of aggregate and sectoral shocks by doing principal...
