This paper utilizes asymptotic expansions of the Edgeworth type to investigate alternative forms of the Wald test of nonlinear restricti ons. Some formulae for the asymptotic expansion of the distribution of the Wald statistic are provided for a general case that should include most econometric...

A new procedure for statistical inference in cointegrating regressions is developed. The author introduces canonical cointegrating regressions (regressions formulated with the transformed data). The required transformations involve simple adjustments of the integrated processes using stationary...

This paper analyzes monthly data on the exchange rates and price indices of the eleven major industrial countries over the modern period of floating exchange rates. It presents tests that are based upon the null hypothesis of cointegration. The paper finds evidence that most country pairs not...

The immense literature and diversity of unit root tests can at times be confusing even to the specialist and presents a truly daunting prospect to the uninitiated. In consequence, much empirical work still makes use of the simplest testing procedures because it is unclear from the literature and...

This paper proposes an approach to testing for coefficient stability in cointegrating regressions in time series models. The test statistic considered is the one-sided version of the Lagrange Multiplier (LM) test. Its limit distribution is non-standard but is nuisance parameter free and can be...

It is shown that the maximum likelihood estimator of a local to unity parameter can be consistently estimated with panel data when the cross-section observations are independent. Consistency applies when there are no deterministic trends or when there is a homogeneous deterministic trend in the...
