“…23 Building on Gould's original work, a sizable literature of gravity-based estimates of the effect of migration on trade has developed. The single most studied reference country is the US (Dunlevy and Hutchinson, 1999;Hutchinson and Dunlevy, 2001;Co et al, 2004;Herander and Saavedra, 2005;Mundra, 2005;Dunlevy, 2006;Millimet and Osang, 2007;Bandyopadhyay et al, 2008;White, 2008, 2010;White, 2007bWhite, , 2009Tadesse, 2008a, 2008b;Jansen and Piermartini, 2009); however, there are also analyses featuring Canada (Helliwell, 1997;Head and Ries, 1998;Ching and Chen, 2000;Wagner et al, 2002;Jiang, 2007;Partridge and Furtan, 2008); the UK (Girma and Yu, 2002;Ghatak et al, 2009); Switzerland (Kandogan, 2009;Tai, 2009); Germany (Bruder, 2004); Denmark (White, 2007a); France (Briant et al, 2009);Spain (Blanes-Cristóbal, 2004; Greece (Piperakis et al, 2003); Italy (Murat and Pistoresi, 2009); the EU 15 (Parsons, 2005); Australia (White and Tadesse, 2007); New Zealand (Bryant et al, 2004) and Malaysia (Hong and Santhapparaj, 2006). 24 Very broadly, and with very few exceptions, these papers consistently find significant positive effects of immigration on trade -whether measured as imports or exports.…”
