Do international flights promote FDI? : the role of face-to-face communication

Air transportation facilitates face-to-face interactions across borders for the spatial expansion of manufacturing production. I investigate the impact of international flights on FDI entry by Japanese firms. I find that FDI entry significantly increases with the weekly frequency of flights from Japan, and the positive impact increases with a proxy for an intensity of face-to-face communication between the parent firm and foreign affiliate. The results are robust to estimation methods, additional control variables, and definitions of face-to-face communication. Thus, the results suggest that flights encourage FDI entry through a reduction in face-to-face communication costs.
