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...

Cointegrating smooth transition regressions with applications to the Asian currency crisis
Saikkonen, Pentti; Choi, In - 2000
This paper studies the smooth transition regression model where regressors are I(1) and errors are I(0). The regressors and errors are assumed to be dependent both serially and contemporaneously. Using the triangular array asymptotics, the nonlinear least squares estimator is shown to be...

Modeling the US short-term interest rate by mixture autoregressive processes
Lanne, Markku; Saikkonen, Pentti - 2000
A new kind of mixture autoregressive model with GARCH errors is introduced and applied to the U.S. short-term interest rate. According to the diagnostic tests developed in the paper and further informal checks the model is capable of capturing both of the typical characteristics of the...

The transmission of German monetary policy in the pre-Euro period
Lütkepohl, Helmut; Wolters, Jürgen - 2001
A small macroeconomic model is constructed to study the transmission of the monetary policy conducted by the Deutsche Bundesbank (DBB) since the middle of the 1970s. For this purpose quarterly, seasonally unadjusted data for the period from 1975 to 1998 are used, that is, the period until the...
