Purpose – The purpose of this paper is to evaluate threshold effects in the persistence of South African aggregate inflation data. Design/methodology/approach – The conventional approach for assessing the degree of persistence within an inflation process is via its integration properties. This study makes use of univariate threshold autoregressive (TAR) models and associated unit root t…
