It explores how the origins of each country’s resource nationalism have influenced their abilities to adapt to a post-hydrocarbon economy. Countries that have adopted social-based policies such as Kuwait and Mexico, transition to renewable energy more slowly in comparison with countries that have adopted market-based policies like the United Arab Emirates (UAE) and Brazil. Understanding these factors expands the literature on energy-rich countries beyond the concepts of the resource curse and rentier states, allowing academics to propose theories that are better suited to the heterogeneous nature of energy-rich countries.
