World Bank's annual report Doing Business (a publication that now covers 11 indicator sets and 185 economies [full report] (PDF). The common factor of the five countries I first mentioned are the only ones that were below Venezuela. OK, the image gave it away! But VENEZUELA (!!) the country with the world's largest estimated oil reserves, so great in fact that they are nearly 25% of OPEC's entire world crude oil reserves (yes, really!).
The Doing Business report "analyzes regulations that apply to an economy’s businesses during their life cycle, including start-up and operations, trading across borders, paying taxes, and protecting investors. The aggregate ease of doing business rankings are based on 10 indicators and cover 185 economies. Doing Business does not measure all aspects of the business environment that matter to firms and investors." Attribution: World Bank. 2013.
