I mentioned on Friday that the World Bank's Enterprise Surveys are a useful source of information to entrepreneurs. It's also informative to compare the concerns across the different countries. In Burundi, electricity is the main problem, by far. It is also the main problem in DRC. In Rwanda, it isn't a problem at all.
Rwandan companies also don't report political instability as a problem, unlike companies in the other two countries. The government in Rwanda is the most established, to the concern of some human rights organisations who find it to be oppressive. One of the best-known newspapers in the UK (The Times) had a critical front page report about their human rights record last week, and their links with the British establishment.
