“…First, FDI helps improve institutional quality (Larrain & Tavares, 2004;Kwok & Tadesse, 2006;Dang, 2013;Long, Ngoc, & My, 2018), and better institutional quality, in turn, reduces shadow economy (Johnson et al, 1998;Friedman et al, 2000;Fugazza & Jacques, 2003;Torgler & Schneider, 2009;Dreher et al, 2009;Dreher & Schneider, 2010;Razmi et al, 2013). Second, FDI has a positive effect on the growth of the formal economy (Romer, 1994;Choe, 2003;Li & Liu, 2005;Long et al, 2018;Mustafa, 2019;Nantharath & Kang, 2019), so that it reduces the size of the shadow economy (La Porta & Shleifer, 2014;Williams, 2008). Third, FDI creates employment (Lall, 1995;Blomström, Fors, & Lipsey, 1997), raises wages (Heyman, Sjholm, & Tingvall, 2007), and improves labor productivity (Le, Duy, & Ngoc, 2019), thus reducing the size of the shadow economy (Boeri & Garibaldi, 2002;Dell'Anno & Solomon, 2008).…”
