The annual structure of real output in the G7 countries is investigated in this article by means of fractional integration techniques. However, instead of using the classical ARMA specifications for describing the short-run components of the series, we use an approach due to Bloomfield (1973)....

Fractionally integrated models with the disturbances following a Bloomfield (1973) exponential spectral model are proposed in this article for modelling UK unemployment. This gives us a better understanding of the low-frequency dynamics affecting the series without relying on any particular ARMA...

In this paper we examine current account sustainability for some European countries. However, instead of using classic approaches based on standard I(0)/I(1) procedures, we use other more recent techniques for unit roots along with fractionally integrated methods. Our findings can be summarized...

The paper examines the monthly structure of the UK unemployment(Claimant Count, (CC)) by means of fractional integration. The study uses a version of Robinson s (1994) tests that permit the test of the unit roots with integer or fractional orders of integration. The results show that the CC...

Annual data of the Canadian real GDP (1871-1998) are examined in this article by means of statistical skills developed for testing I(d) statistical processes. The results show that when looking at the whole range of data, the unit root hypothesis is rejected in favor of more nonstationary...

The order of integration of different measures of the U.K. unemployment is investigated in this paper by means of semiparametric techniques. Several methods, such as the R/S statistic, along with others proposed by Robinson in a number of papers are applied in this article. The methods perform...

The Feldstein-Horioka (FH) puzzle, that is the strong correlation between saving and investment in a world where obstacles to capital mobility are limited, has been studied extensively since it was exposed in 1980. Even though the theoretical and empirical literature has examined many of its...
