“…This research, which is surveyed in Antràs and Yeaple (2014), has investigated theoretically and empirically several mechanisms through which firm boundaries are extended using FDI. A non-exhaustive list of the mechanisms that have been shown to be important includes the relative location of firms along a global value chain and the elasticity of final demand (Antràs and Chor, 2013), final product prices (Alfaro et al, 2016), the relative contractibility of upstream and downstream production stages (Alfaro et al, forthcoming), and intangible assets and intellectual property rights protection (Bolatto et al, 2017). When we take the model to the data, we control for these alternative explanations of FDI.…”
