The recently examined durability-asymmetry hypothesis of Cook (1999) is re-evaluated using the diagnostic tests of time deformation proposed by Stock (1987, 1988). An application of these tests to disaggregated data on U.S. consumers’ expenditure provides further support for this hypothesis,...

In this paper three hypotheses concerning the cyclicality of U.S. consumers' expenditure are proposed. These hypotheses are based upon the distinction between expenditure on durable and non-durable goods. It is argued that durability will lead to increased cyclical sensitivity and that this...

In this letter the question of whether the consumption-income ratio is mean reverting is revisited. To address known problems of low power associated with previous studies, more powerful modifications of the Dickey-Fuller (DF) test are applied. The results of weighted symmetric and recursively...

The literature on testing for the presence of cyclical asymmetry in consumers' expenditure is extended via the application of tests for time deformation to UK data subject to a high degree of disaggregation. The initial empirical findings provide evidence of significant time deformation in...

The properties of the Granger-Lee (Journal of Applied Econometrics, 4, S145-59, 1989) asymmetric error correction model under consistent-threshold estimation are considered, with the relationship between the threshold range and rejection of the symmetry hypothesis examined. The results of Monte...

The power properties of the rank-based Dickey-Fuller (DF) unit root test of Granger and Hallman [C. Granger and J. Hallman, Nonlinear transformations of integrated time series, J. Time Ser. Anal. 12 (1991), pp. 207-218] and the range unit root tests of Aparicio et al. [F. Aparicio, A. Escribano,...

The philosophy of science literature has played an increasing role in discussion of econometric methodology in recent years, and the Hendry methodology in particular has received much attention. Despite this, the encompassing principle has been overlooked in the methodological literature. This...

The now familiar error correction model has recently been extended to allow for the modelling of asymmetric behaviour, resulting in the development of the asymmetric error correction model. Previous workers have undertaken studies upon which the 'classic', implicitly symmetric, error correction...

The asymmetric unit root tests of Enders and Granger (Journal of Business and Economic Statistics, 16, 304-11, 1998) are examined using consistent threshold estimation and the original two-step procedure. In contrast to earlier studies, the ability of the tests to jointly reject the unit root...

The relationship between the initial condition of time series data and the power of the Dickey-Fuller (1979) test and a number of modified Dickey-Fuller tests is examined. The results obtained extend the asymptotic analysis of Muller and Elliott (2003) by both focussing upon finite-sample power...
