This paper considers the application of long memory processes to describe inflation with seasonal behaviour. We use … inflation rates of four different countries, USA, Canada, Tunisia, and South Africa. The analysis is carried out using the … persistence is a common feature for inflation series.

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 …
