Davidson et al.'s data set is used to demonstrate the existence of a significant asymmetry in the adjustment of consumption towards equilibrium. The Granger-Lee and Escribano-Pfann methods of partitioning the error correction term are compared and it is shown that the latter produces better...

The size distortion of the Dickey-Fuller (Journal of the American Statistical Association, 74, pp. 427-31, 1979) unit root test is examined in the presence of structural changes in both the level and variance of integrated time series. In contrast to previous studies, the empirically relevant...

A class of smooth transition momentum-threshold autoregressive (ST-MTAR) tests is proposed to allow testing of the unit root hypothesis against an alternative of asymmetric adjustment about a smooth nonlinear trend. Monte-Carlo simulation is employed to derive finite-sample critical values for...

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 literature on testing for the presence of cyclical asymmetry in UK consumers' expenditure is extended via the application of nonparametric tests to data subject to a higher degree of disaggregation than considered in previous studies. The results obtained at an intermediate level of...

Critical values for a test for cointegration are generated based on the joint significance of the levels terms in an error-correction equation. It is shown that the appropriate critical values are higher than those derived from the standard F-distribution. The power properties of this test are...

Empirical estimation of Phillips curve relationships typically indicates the presence of parameter instability. This is argued to be due to the fact that the parameters of these equations are reduced form rather than structural parameters. Estimation of a Phillips curve model by methods which...

This paper presents estimates of price functions for beef, lamb and pork for the UK economy which allow for the effects of the 1996 BSE crisis. The estimates illustrate the importance of allowing for the joint endogeneity of prices in these markets. This shown that the effects of this crisis had...

This paper presents some simulation results for a small Structural Vector Autoregression model of the interaction between real output and prices for the UK economy. The model is estimated using quarterly data over the period 1966:2 to 1995:4. The effects of alternative identifying restrictions...
