“…Some of these studies use static time series models to test the equality hypothesis, and others (Cavaglia, 1992;Chung and Crowder, 2004;Dutton, 1993;Fraser and Taylor, 1990;Gaab, Granziol and Horner, 1986;Goodwin and Grennes, 1994;Kugler and Neusser, 1993;Mark, 1985aMark, , 1985bMishkin, 1984a;Modjtahedi, 1988;Parikh, 1994;Patel and Akella, 1996;Shrestha, 1999) use dynamic time series models, including cointegration models. In this present study, a model is considered dynamic if it uses lagged series.…”
