Usually, the time series of electricity prices in different markets show structural changes due to economic conditions related to supply, demand or specific market rules. While some of the proposals for modeling these series are based on mean reversion models inspired by the financial literature...

We show that the CUSUM-squared based test for a change in persistence by Leybourne et al. (2007) is not robust against shifts in the mean. A mean shift leads to serious size distortions. Therefore, adjusted critical values are needed when it is known that the data generating process has a mean...

This paper considers tests for cointegration with allowance for structural breaks, using the extrema of residual-based tests over subsamples of the data. One motivation for the approach is to formalize the practice of data snooping by practitioners, who may examine subsamples after failing to...

This paper performs a system cointegration analysis of UK money demand based on real money, real income, the opportunity cost of holding money, and inflation for the period 1873 - 2001. As a novelty we account for the effect of the world wars by estimating additive data corrections, allowing...
