The article examines how different exchange rate policies in Nigeria affect the country's economic growth. The researchers used a method called Vector Error Correction Model to analyze data from 1980 to 2016. They found that both fixed and flexible exchange rate policies have a positive impact on Nigeria's economic growth. The study also showed that changes in the real effective exchange rate influence economic growth, and there is a one-way relationship between oil prices and real interest rates in Nigeria. The researchers suggest that policy changes are needed to address distortions in the foreign exchange market and diversify Nigeria's export base away from relying solely on oil.
