The finite-sample properties of recently proposed range unit root tests are examined in the presence of serial correlation and drift. The results obtained show that both tests suffer from severe size distortion when applied to unit root process which either possess serially correlated...

Cook, Holly, and Turner recently developed a hypothesis of a positive relationship between the durability of consumers' expenditure and the asymmetric behaviour it exhibits. Supportive evidence was found by applying Sichel's tests of business cycle asymmetry to the component series of UK...

The research of Leybourne and Newbold (2003) is extended to examine the finite-sample size of the weighted symmetric cointegration test when applied to independent unit root processes subject to structural change. The results obtained show the weighted symmetric cointegration test to be more...

While there is disagreement concerning the integrated nature of US Gross domestic product (GDP) over the long-run, there is a consensus that it is best characterized as I(1) over the post-World War II period. In this article the existing literature is extended via the use of an exponential...

The literature on testing for the presence of cyclical asymmetry in consumers' expenditure is extended via the application of tests for time irreversibility to UK data subject to a higher degree of disaggregation than considered in previous studies. The empirical findings reported provide...

The consistent threshold estimation method is used to improve the threshold specification of the Granger-Lee asymmetric error correction model. Although only previously considered in the context of univariate analysis, the approach is found to uncover asymmetry undetected under the typical...

In recent research Leybourne and co-workers examined the behaviour of the Dickey-Fuller τ test in the presence of structural breaks under the null. It was found that breaks in either level or drift occurring early in the sample period resulted in severe size distortion, with the unit root...

The potential forecasting bias of asymmetric error correction models is examined via an application of the Granger and Lee and Escribano and Pfann specifications to the earlier data of Davidson et al. Cook's results concerning sample space regularities are extended, with partitioning of the...
