Is there Really a Unit Root in the Inflation Rate? More Evidence from Panel Data Models

  • Basher, Syed A.
  • Westerlund, Joakim

Time series unit root evidence suggests that inflation is nonstationary. By contrast, when using more powerful panel unit root tests, Culver and Papell (1997) find that inflation is stationary. In this paper, we test the robustness of this result by applying a battery of recent panel unit root tests. The results suggest that the stationarity of inflation holds even after controlling for crosssectional dependence and structural change.
