“…Our paper is related to the literature on the propagation of shocks through network linkages between firms within an economy as theoretically studied by and Kelly, Lustig, and van Nieuwerburgh (2013), and empirically examined by Barrot and Sauvagnat (2016), Hertzel, Li, Officer, and Rodgers (2008), Kolay and Lemmon (2011), Kose and Yi (2001), Johnson (2014), and Wu (2016) (see surveys by Acemoglu et al (2015) and Carvalho (2014)). Our focus, however, is on the propagation of shocks through linkages within firms but across national borders.…”
