This paper provides an extensive Monte-Carlo comparison of severalcontemporary cointegration tests. Apart from the familiar Gaussian basedtests of Johansen, we also consider tests based on non-Gaussianquasi-likelihoods. Moreover, we compare the performance of these parametrictests with tests...

This paper considers Lagrange Multiplier (LM) tests for determining the cointegrating rank of a vector autoregressive system. In order to deal with outliers and possible fat-tailedness of the error process, non-Gaussian like-lihoods are used to carry out the estimation. The limiting...

We suggest improved tests for cointegration rank in the vector autoregressive (VAR) model and develop asymptotic distribution theory and local power results. The tests are (quasi-)likelihood ratio tests based on a Gaussian likelihood, but of course the asymptotic results apply more generally....
