Abstract

Using a panel smooth threshold regression to analyze data from 17 Middle East and North Africa (MENA) countries, this study investigates how asymmetries in energy price (EP) fluctuations impact renewable energy (RE) development, considering varying economic growth rates. The findings reveal that EP fluctuations influence RE development differently across income levels. In high-income countries, higher EPs stimulate RE expansion, while in low-income nations, they hinder it. These results support the substitution hypothesis, indicating that higher EPs encourage a shift toward alternative RE sources, though only within the high-GDP per capita regime in the MENA region. This evidence challenges the notion of a one-size-fits-all energy policy for MENA, highlighting the need for tailored strategies based on individual countries' economic contexts. High-income nations should prioritize subsidy removal to incentivize RE investments, whereas low-income countries require phased approaches to maintain economic stability. The study's broader implications extend to global energy policy, advocating for differentiated strategies that balance sustainable energy transitions with economic growth.
