The study looked at how changes in oil prices affect Nigeria's economy and government policies. They used a special model to see how monetary and fiscal policies react to these oil price shocks. The researchers found that oil price shocks have a big impact on things like inflation, government spending, and interest rates. They also discovered that government spending is more stable than oil revenue and interest rates. Inflation is more affected by oil prices than by monetary policy. The study suggests that Nigeria should balance its fiscal and monetary policies carefully to keep the economy stable. It also recommends reducing government reliance on oil revenue and improving financial tracking systems.
