This paper first establishes a selection of stylized facts for high-frequency cointegration processes in the European …,1) processes are used to model the cointegration relationship. Furthermore, this cointegration relationship is contaminated with … jumps. Based on these processes, the power and size properties of ten contemporary cointegration tests are assessed. We …

This paper studies the robust estimation and inference of threshold models with integrated regres- sors. We derive the asymptotic distribution of the profiled least squares (LS) estimator under the diminishing threshold effect assumption that the size of the threshold effect converges to zero....

We examine a kernel regression smoother for time series that takes account of the error correlation structure as proposed by Xiao et al. (2008). We show that this method continues to improve estimation in the case where the regressor is a unit root or near unit root process.
