Unemployment and input prices : a fractional cointegration approach
Caporale, Guglielmo Maria; Gil-Alaña, Luis A. - 2000
This paper examines the relationship between unemployment, real oil price and real interest rates in Canada. Instead of following the classical approach based on I(0) stationarity or I(1) cointegrating relationships, we use fractional integration/cointegration techniques which allow for the...

Fractional integration and the dynamics of UK unemployment
Gil-Alaña, Luis A.; Henry, S. G. B. - 2000
This article is concerned with the dynamic behaviour of UK unemployment. However, instead of using traditional approaches based on I(0) stationary or I(1) (integrated and/or cointegrated) models, we use the fractional integration framework. In doing so, we allow for a more careful study of the...

A fractionally integrated model with a mean shift for the US and the UK real oil prices
Gil-Alaña, Luis A. - 2000
In this article we model the log of the U.S. and the U.K. real oil prices in terms of fractionally integrated processes with a mean shift. We use different versions of the tests of Robinson (1994), which have standard null and local limit distributions. The results indicate that if we model the...

Testing for short and long-run causality : the case of the yield spread and economic growth
Breitung, Jörg; Candelon, Bertrand - 2001
To assess the predictive content of the interest rate term spread for future economic growth, we distinguish short-run from long-run predictability by using two different approaches. First, following Dufour and Renault (1998) a test procedure is proposed to test for causality at different...
