Global Economic Policy Uncertainties and International Oil Price Volatility Under Alternative Market Conditions

The results clearly show that the GEPU-oil price volatility nexus is episodic in nature. While evidence of mean reverting stance is confirmed across the sectionalized market phases, the long-term impact of GEPU in the nexus holds true for the Covid-19 pandemic, Russia-Ukraine war, and oil price shock episodes.
