A large part of the literature about Foreign Direct Investment (FDI) analyzes the associations between FDI and the factors that affect its location. Some of the motivations to explain these relationships are because FDI flows have dramatically increased, and in developing countries, are the most important source of external financing and a channel to transfer technology that contribute to economic growth. Some of the studied relationships include the effects of exchange rate on FDI (e.g., Barrel & Pain, 1996; Cushman, 1985, 1988; and Pain, 2003); the relationship between labor costs and FDI (e.g., Culem, 1988; Cushman, 1987; and Love & Lage-hidalgo, 2000); the association between political aspects and FDI (e.g., Haggard, 1989; Nigh,1985; and Tuman & Emmert, 2004); the effect of trade issues such as openness, trade protection and trade agreements on FDI (e.g., Agosin & Machado, 2006; Barrel & Pain, 1999; and Waldkirch, 2003); and the relationship between host country market size and FDI (e.g., Barrel &Pain, 1996; and Love & Lage-hidalgo, 2000).
In addition, positive associations between FDI and growth include Bengoa and Sanchez-Robles (2003), Campos and Kinoshita (2002), Hansen and Rand (2006), Li and Liu (2005), and Oliva and Rivera-Batiz (2002). The literature on the determinants of FDI reports market size as the most influential determinant of FDI. In this literature, one of the proxies used for market size is per capita GDP and represents the income level of the host country, so that it is likely that an increase in per capita GDP will increase the market size for the goods and services produced by the multinational firms?
