“…The approaches have evolved overtime from single equation models (Hooper and Mann, 1989;Campa and Goldberg, 2005;Choudhri and Hakura, 2006) to simultaneous equation approach (Zorzi et al, 2007) to various types of Vector Autoregressive (VAR) and panel data estimation approaches. These include the recursive VAR (McCarthy, 2000;Loloh, 2014, Maka, 2013 structural VAR (Gagnon and Ihrig, 2004;Sanusi, 2010;An and Wang, 2012), the vector error correction models (Frankel et al, 2012;Karoro et al, 2009;Yanamandra, 2015) and panel estimation techniques (Bailliu and Fujii, 2004;Barhoumi, 2006).…”
