“…Gençay et al (2001) and Ramsey (2002) provide ample exposition on the use and versatility of wavelet techniques in economics and finance. During the past decade the methodology gained currency and relevant applications of wavelets include analyses of stocks (Fernandez, 2006(Fernandez, , 2008In and Kim, 2006;Rua and Nunes, 2009), commodities (Vacha and Barunik, 2012;Graham et al, 2013;Reboredo and Rivera-Castro, 2014a), exchange rates (Nekhili et al, 2002;Karuppiah and Los, 2005;Nikkinen et al, 2011), and other financial and economic variables or their interactions In, 2005, 2007;Faÿ et al, 2009;Rua, 2010;Aguiar-Conraria and Soares, 2011;Gallegati et al 2011;Aguiar-Conraria et al, 2012;Reboredo and Rivera-Castro, 2014b). By using wavelets we are able to test the hypothesis on the existence of homogeneity in dynamic correlations across various investment horizons among assets, an issue that so far has been largely overlooked in the literature.…”
