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...

A fractionally integrated exponential model for UK unemployment

Gil-Alaña, Luis A. - 2000

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

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...

Fractional cointegration and real exchange rates

Caporale, Guglielmo Maria; Gil-Alaña, Luis A. - 2000

This paper uses fractional integration and cointegration in order to model the DM/dollar and the yen/dollar real exchange rates in terms of both monetary and real factors, more specifically real interest rate and labour productivity differentials. We find that whilst the individual series may be...

Some nonparametric tests for unit roots and cointegration

Breitung, Jörg - 1999

Following Bierens (1997a,b) and Vogelsang (1998a,b), unit root tests can be constructed which are asymptotically invariant to parameters involved by the short run dynamics of the process. Such an approach is called nonparametric by Bierens (1997b) and can be used to test a wide range of...

Testing for a unit root in a time series with a level shift at unknown time

Saikkonen, Pentti; Lütkepohl, Helmut - 1999

step and apply standard unit root tests to the residuals. The estimation of the nuisance parameters is done in such a way …

Testing of unit roots and other fractionally integrated hypotheses in the presence of structural breaks

Gil-Alaña, Luis A. - 2000

Tests for unit roots and other nonstationary hypotheses that were proposed by Robinson (1994) are applied in this article to the Nelson and Plosser's (1982) series. The tests can be expressed in a way allowing for structural breaks under both the null and the alternative hypotheses. When...

Comparison of unit root tests for time series with level shifts

Lanne, Markku; Lütkepohl, Helmut; Saikkonen, Pentti - 1999

previously suggested tests of this sort are analyzed and a range of modifications is proposed which take into account estimation … errors in the nuisance parameters. An important result is that estimation under the null hypothesis is preferable to … estimation under local alternatives. This contrasts with results obtained by other authors for time series without level shifts. …

Unit root tests for time series with level shifts : a comparison of different proposals

Lanne, Markku; Lütkepohl, Helmut - 2001

A number of unit root tests which accommodate a deterministic level shift at a known point in time are compared in a Monte Carlo study. The tests differ in the way they treat the deterministic term of the DGP. It turns out that Phillips-Perron type tests have very poor small sample properties...
