In this paper, tests for fractional cointegration that allow for structural breaks in the long-run equilibrium are … proposed. Traditional cointegration tests cannot handle shifts in fractional cointegration relationships, a limitation … addressed here by allowing for a time-dependent memory parameter for the cointegration error. The tests are implemented by …

cointegration. Critical values and the power of the tests under the alternative of fractional cointegration are simulated and …

essential step in testing for (fractional) cointegration in the bivariate case. For the multivariate case, there are several … versions of cointegration, and the version given in Robinson and Yajima (2002) has received much attention. In this definition … integration order. Furthermore, this time series vector is said to be cointegrated if there exists a cointegration in any of the …
