“…In most of the literature, GDP or GNP, which stands for economic market size, is usually adopted as a proxy for market size (Bilgili, Tülüce, & Do gan, 2012;Braunerhjelm & Svensson, 1996;Cuyvers et al, 2011;Filippini & Molini, 2003;Venables, 1999). To a less extent, population, which stands for the absorption ability of international trade, is also used (Ekanayake, Mukherjee, & Veeramacheneni, 2010;Filippini & Molini, 2003;Papazoglou, 2007;Kien, 2009). It should be pointed out that, while population may remain unchanged and change on a piecemeal basis, market size can rise rapidly, especially in developing countries.…”
