The objective of this paper is to investigate the influence of the monetary policy and other shocks on the gross domestic product of each one of the Brazilian regions. The methodology is a combination of non-observed components and auto-regressive techniques (VAR). Common and specific shocks and common and specific effects of these shocks had been identified. The results indicate that Brazilian regions have symmetric responses to the common shocks but the most important shocks are the idiosyncratic ones.
