Professor Stiglitz did review the role of political dysfunction such as corrupt and undemocratic governments in the resource curse and antidotes for them in the 3rd, 4th, and 5th paragraph.
He then argued that these antidotes are necessary, not sufficient. Resources-rich countries need a strategy to negotiate with MNCs to gain the biggest price for their resources and use the revenue to industrialize their economies.
Uncorrupt and democratic governments are not necessarily wise ones. And professor Stiglitz gave them his advices for free. He definitely should be proud of his Nobel prize.
Is it any wonder that economics is in such sorry state that a critic of Nobel laureate even can read a non-technical article right?
