The Prachowny and the Attfield and Silverstone conclusions of non-stationarity may depend on the method of constructing the gaps, either via a production function approach as in the Prachowny and Attfield and Silverstone (1997), or via a Beveridge-Nelson decomposition as in Attfield and Silverstone (1998), or on the low power of the unit root tests employed.
