Unit Roots and Smooth Transitions: A Replication

  • Kulaksizoglu, Tamer

Abstract

This paper replicates Leybourne et al. (1998), who propose a Dickey-Fuller type test for unit root that is most appropriate when there is reason to suspect the possibility of deterministic structural change in the series. We find that our replicated results are quite similar to the authors' results. We also make the Ox source code available.
