5. Discussion
While previous scholarship has measured the impact of BITs through their presence by using the number of these bilateral agreements in a particular time period or a dummy for BIT presence (Desbordes & Vicard, 2009; Elkins et al., 2006; Jandhyala & Weiner, 2014; Neumayer & Spess, 2005; Tobin & Rose-Ackerman, 2011), we break new ground by introducing the construct of BIT stringency a variable capturing differences in the design of BITs across the world. This is a more nuanced measurement than the simple presence (and count) of BITs and will allow researchers to open up new lines of enquiry into how international investment agreement design influences not only FDI flows, but also MNE strategy. While scholars have raised awareness of divergence in the content of BITs (Berger et al., 2013; Sachs & Sauvant, 2009; Sornarajah, 2004), there has been a notable gap in research into how the design features of these agreements influence MNE strategy. Our study addresses this gap.
