In this paper we use the approximate bias expressions developed in Yu (2012) and Bao et al. (2013) to improve the testing of the ordinary least squares or quasi-maximum likelihood estimator of the mean reversion parameter in continuous time models. We follow the approach given in Iglesias and...

In the context of limited dependence at large lags, Andrews (2002) showed the magnitudes of the error in rejection probabilities of the symmetric two-sided block bootstrap t, Wald and J tests. Andrews (2004) introduced the block-block bootstrap and proved that it obtained better asymptotic...
