“…Others have focused on developing time series and statistical methods for isolating trend and cyclical components and analysing their interaction (such as Harding and Pagan, 2002;Zarnowitz and Ozyildirim, 2006). Several others have been mainly concerned with assessing changes in the synchronicity of regional business cycles over time (for example, Owyang et al, 2005;Tondl and Traistaru-Siedschlag, 2006;Montoya andDe Haan, 2008: Hayashida, andHewings, 2009;Panteladis and Tsiapa, 2011;Bierbaumer-Polly, 2012). Yet others have examined the implication of asymmetries in regional business cycles for monetary integration and common currency areas (Bayoumi and Eichengreen, 1993;Krugman, 1993;Frankel and Rose, 1998;Barrios, Brülhart, Eliot and Sensier, 2003;Barrios and Lucio, 2003;Partridge and Rickman, 2005).…”
