Separate from the fact that shoe-selling may or may not be a good business idea (...being married and observing women around me, I'd say, it is... and all shoe stores appear to be booming around here), I think the topic of selling to a possibly instable country is a very interesting one...
I've been heavily investing in Ecuador. As I already wrote in by blog (here:
http://kivaramon.blogspot.com/2007/03/soon-to-be-republica-bolivariana-de.html) Ecuador is hard on their way to become a socialist state. Generally, not good for business...
Ecuador's advantage is that they dollarized their economy. It's gonna be hard to put import restrictions, and their money can't really devaluate against... eh... itself, the dollar.
As for the Ukraine, I think that the concerns are mainly focused around two things:
- devaluation of the local monetary unit. One of Kiva's loan conditions is for the MFI (and thereby, generally the borrower) to take the currency exchange risk. Chances are, that if Ukraine goes the way of Zimbabwe, your entrepreneur won't be able to pay back the loan
- political change towards more restrictive money export rules. If that's the case, the MFI may not be able to pay back to Kiva.
