Interesting. At the same time, there is always an upside to higher risks(one way to think about vulnerability). One possible upside is the potential of reaping high growth and faster returns, as smaller countries adjust faster to changes. Especially disruptive innovations. Perhaps in this sense your approach allows for a measurement for innovative tendencies of small nation's, the premise being having to innovate in order to surmount the vulnerabilities they face.
Small states may be as complex as large ones. Multi-layered complexities at the small state level may warrant the use of multiple methodologies.

Jacob, just saw this comment. Absolutely relevant. One of the comments I got from the referees is that my paper at this point is not clustering countries. For this project, that was the point; however, I want to further investigate this, so your analysis seems like a good angle to this. What email address you are using? Lets talk further
This topic is extremely relevant. This would be an interesting and helpful addition to this literature. There are some works from UWI on this issue, but I have not seen it done with this methodology. Looking forward to seeing it in print.
