Despite the dominance of the “resource curse” paradigm for the last decades, some analysts criticized it and some assert that a few countries managed their rent instead as a “blessing”. The performance of Canada, Norway and even Botswana (as a major producer of diamonds) balances in fact the previous results. They all show that natural resources discoveries can have positive impacts on countries, contradicting the « resource curse » theory. Building on this intuition, we can now turn to analyzing the present case of Gulf countries: do they also suffer from a curse, or have they also transformed the rent into a positive parameter?
