Leybourne et al. (J. Econom. 87 (1998) 191) have shown the Dickey-Fuller (J. Amer. Statist. Assoc. 74 (1979) 427) unit root test to suffer from severe oversizing in the presence of level breaks. In this paper it is shown that recursive mean adjustment can correct this distortion, even for large...

The properties of modified Dickey-Fuller tests are examined when applied to momentum threshold autoregressive processes. The tests are found to possess high power, outperforming the standard Dickey-Fuller test and even the asymmetric momentum threshold autoregressive unit root test. The results...

Recent research has shown the momentum-threshold autoregressive (MTAR) unit root test of Enders and Granger (J. Business Econom. Statist. 16 (1998) 304) to exhibit less power than modified Dickey-Fuller tests when applied to MTAR processes. In this paper a revised MTAR test is proposed which...

In recent research, Leybourne and Newbold have shown commonly employed tests of cointegration to exhibit spurious rejection when applied to independent unit root processes subject to breaks in either level or trend. In the present paper, this research is extended to consider the finite-sample...

In recent research, Kanioura and Turner (2005) have proposed an F-test for cointegration based upon the joint significance of the level terms in an error correction model. In the present study, the analysis of this test is extended via comparison with the GLS-based cointegration test of Perron...

In this letter tests for asymmetric dynamic behaviour are applied to Australian consumers expenditure. In contrast to recent findings for the UK provided by the seminal work of Holly and Stannett (1995), where asymmetric behaviour is found in the form of heightened levels during booms,...

While there exist numerous applications of Kuhn's analysis of scientific revolutions to economics, there is yet to be an application to econometrics. The present paper addresses this via an analysis of the often-documented transition between the textbook and LSE methodologies witnessed in...
