Contracting with Whom? The Differential Effects of Investment Treaties on FDI

Under what conditions can governments use international commitments such as Bilateral Investment Treaties (BITs) to attract foreign direct investment (FDI)? Although numerous studies have attempted to answer this question, none considers how investment treaties may have heterogeneous affects across industry. I argue BIT effect is strongest when the obsolescing bargaining problem between firms and governments is most protracted, namely, when FDI relies on strong contracts between firms and states. Using a time series cross-sectional data set of 114 developing countries from 1985 to 2011, I find BITs are associated with increases in infrastructure investment, an industry particularly reliant on the sanctity of government contracts, but not with total FDI inflows. Moreover, BITs with strong arbitration provisions display the strongest statistical effect on infrastructure investment, while BITs that do not provide investors with such protections are not associated with increased investment. My results have implications for both scholarship on the relationship between governments and multinational firms as well as for the study of international institutions more broadly. To properly ascertain the effects of international treaties and institutions, scholars should consider not just whether institutions constrain or inform—or matter at all—but also the extent to which the targets of institutions have heterogeneous responses to them.
