For emerging markets we should mention research provided for: − ASEAN (Janakiraman, Lamba, 1998;Gosh et al, 1999;Masih, Masih, 2001;Siklos, Ng, 2001), − Middle and South Americas (Phylaktis, Ravazollo, 2005;Diamandis, 2009) and − Central and Eastern Europe (Voronkova, 2004;Gilmore et al, 2008;Syllignakis, Kouretas, 2010). Taking into account length of the investigated samples we notice that 10-year or longer periods are very often considered, for instance (Caporale, Spagnolo, 2010;Gilmore et al, 2008;Sharkasi et al, 2004).…”
