Unemployment and input prices : a fractional cointegration approach
Caporale, Guglielmo Maria; Gil-Alaña, Luis A. - 2000
following the classical approach based on I(0) stationarity or I(1) cointegrating relationships, we use fractional integration/cointegration … three variables are I(1). But we only find cointegration in the presence of autocorrelated disturbances, which means that … opposed to classical cointegration, which implies long memory and slow reversion to equilibrium. This suggests that an …

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...

Nonlinear error correction and the efficient market hypothesis : the case of German dual-class shares
Breitung, Jörg; Wulff, Christian - 1999
The efficient market hypothesis implies that asset prices cannot be cointegrated. On the other hand, arbitrage processes prevent prices of fundamentally related assets from drifting far away. An attractive model that reconciles these two conflicting facts is the nonlinear error correction...

Modelling seasonality with fractionally integrated processes
Gil-Alaña, Luis A. - 2000
We propose in this article the use of a particular version of the tests of Robinson (1994) for testing seasonally fractionally integrated processes. The tests have standard null and local limit distributions and allow us to test unit and fractional seasonal roots even with different amplitudes...

Testing stochastic cycles in macroeconomic time series
Gil-Alaña, Luis A. - 2000
A particular version of the tests of Robinson (1994) for testing stochastic cycles in macroeconomic time series is proposed in this article. The tests have a standard limit distribution and are easy to implement in raw time series. A Monte Carlo experiment is conducted, studying the size and 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...
