“…Various papers investigated whether there is a so-called "J-curve", with devaluations leading to a short-run deterioration of the TB but a long-run improvement (see Bahmani-Oskooee, 1985;Rahman, Mustafa, and Burckel, 1997;Himarios, 1989;Rose and Yellen, 1989;Briguglio, 1989;Noland, 1989;Rose, 1990;Berument, 2005), with mixed results. Most studies use bilateral aggregate data (see, e.g., Boyd et al, 2001;Lal, and Lowinger, 2002;Onafuwora, 2003;McDaniel, and Agama, 2003;Fullerton and Sprinkle, 2005;Bahmani-Oskooee et al, 2006;Narayan, 2006;Bahmani-Oskooee, and Hegerty, 2011;Dash, 2013;Costamagna, 2014), again providing mixed evidence.…”
