Powerful nonparametric seasonal unit root tests

Burak Alparslan Eroğlu, Kemal Çağlar Göğebakan and Mirza Trokić

Economics Letters, 2018, vol. 167, issue C, 75-80

Abstract: This paper introduces a powerful nonparametric testing procedure for seasonal unit roots by utilizing the fractional integration operator. Different from the well-known seasonal unit root tests of Hylleberg et al. (1990), the proposed tests do not require any parametric specifications.
