This paper investigates the impact of different depreciation methods on the dynamic characteristics of the Greek regional net fixed capital series. Using annual data over the period from 1974 to 2006, Karpetis and Zikos (Int J Econ Res 11(2):333–354, 2014) constructed the series of nominal net fixed capital in the case of the thirteen administrative regions of Greece, applying four different depreciation methods of capital. In the context of the present analysis, these series were initially deflated, using the country’s G.D.P. deflator (2005 = 100), and subsequently were exploited to investigate their dynamic characteristics through estimation of the best fitted ARIMA(p,d,q) models and determination of the roots of the characteristic polynomials. The statistical findings reveal, firstly, the impact of the employed depreciation methods of capital on the evolutionary pattern (monotonic or sinusoidal) of the series and secondly, the slow convergence of the Greek regional net fixed capital towards its long-run equilibrium value.
