According to Millar and Rietveld (2015), what are three explanations to why natural resource wealth can become a resource curse?
O There are no booms in natural resource prices in the international market.
O When the country has weak institutions there is poor management of natural resource wealth.
O The curse lies in the inability to find sufficient foreign investments to develop a mining industry and extract the resources and they are therefore left in the ground.
O There is a long-term decline in commodity prices in the international market.
O If the natural resource dependency leads to a lack of diversification of the economy.
