Oil price shocks and macroeconomic dynamics in resource-rich emerging economies under regime shifts

How do global oil price fluctuations affect macroeconomic activity and monetary policy in resource-rich emerging economies? This paper tackles this question by developing a unified emerging market/rest-of-the-world DSGE framework featuring Ricardian and Non-Ricardian households, an oil-producing sector, a fuel subsidy programme, and a regime-switching process. The model is estimated using Bayesian methods, allowing us to be agnostic regarding regime shifts in the monetary policy rule and oil price volatility. Using data for Nigeria, we find substantial empirical support for the regime-switching behaviour and discuss how macroeconomic implications of oil price shocks may vary depending on the nature of the shock, monetary policy responses, and the fuel subsidy policy in place. Apart from providing important insights into the monetary policy transmission mechanism, the paper offers a novel, flexible, and functional model for future policy analysis, especially in resource-rich emerging countries.
