All of the tests considered are based on the null hypothesis of serial independence and all are in regular use by applied econometricians. Similarly, the non-standard conditions under which these tests are analysed are intended to represent situations which can reasonably be expected to occur in practice. It is therefore expected that the results reported in this thesis will be of direct benefit to the econometrics profession in the form of an improved understanding of the effects of mis-specification.enCopyright John P.
