Employing the modified tests of Harvey, Leybourne and Taylor [Harvey, D.I., Leybourne, S.J. and Taylor, A.M.R., 2006. Modified tests for a change in persistence. Journal of Econometrics 134, 441-469.] for a single change in persistence and repartitioning the sample when a break is found, this...

We study estimation of the date of change in persistence, from I(0) to I(1) or vice versa. Contrary to statements in the original papers, our analytical results establish that the ratio-based break point estimators of Kim [Kim, J.Y., 2000. Detection of change in persistence of a linear time...
