The PPP debate: Multiple breaks and cross-sectional dependence


  • Snaith, Stuart


This study implements panel unit root PPP tests accommodating level and trend breaks and cross-sectional dependence. In the presence of breaks there is evidence of a currency and price index effect. Additionally accounting for cross-sectional dependence overturns support for PPP.
