This study was conducted to examine business cycles and identify significant factors affecting these cycles using Bayesian Vector Autoregressive (BVAR) in presence of institutional, political and global factors in five oil exporting countries including Canada, Iran, Nigeria, Norway and Venezuela during 1995-2016. The results of Forecast Error Variance Decomposition (FEVDs) indicated that short-term GDP had the maximum value in justifying instability. In long term, the role of GDP was decreased due to increasing role of other variables. so that at the end of periods except Iran, Nigeria and Venezuela oil shock in Canada and financial shock in Norway are the reasons for the business cycles. Moreover, findings show that political and institutional factors have changed the role of shocks and impulses. so that the impact of effective shock has decreased in instability during long term. Political and institutional factors had the considerable role in Iran and Norway, respectively. It is suggested that policymakers, before deciding on policies, first by the model used in this research examine economic and non-economic variables affecting the business cycle, and then apply appropriate monetary and fiscal policies.
