In this paper, we propose new simple innovational outlier (IO) panel unit root tests with a break. A bootstrap method for dealing with cross-sectional dependence is provided and small sample properties of the bootstrap tests are investigated by Monte Carlo experiments. The panel innovational outlier unit tests are then applied to a panel of 22 OECD inflation rates.
