In his study of the 'resource curse,' economist Jeffrey Sachs examined why nations with an abundance of natural resources—such as oil or minerals—often experience slower economic growth than resource-poor countries. Sachs argues that a reliance on raw material exports can lead to 'Dutch Disease,' where a surge in currency value makes other sectors, like manufacturing, less competitive globally. Furthermore, the volatility of commodity prices can create a cycle of 'boom and bust' that hampers long-term investment.
