This paper investigates the effects of time-varying variance on the linear trend tests proposed by Harvey et al. (2007) (HLT) and Perron and Yabu (2009) (PY) and finds time-varying variance results in obviously different null distributions. We propose two new robust linear trend tests. An empirical application highlights the usefulness of our tests.
