The purpose of this handbook is to document the expert knowledge relevant for Norges Bank’s conduct of monetary policy. Its primary focus is to elaborate on the topics and policy challenges described in Norges Bank’s monetary policy strategy statement. We will cite international practice and relevant literature regarding these topics and give an account of Norges Bank’s interpretations and clarifications. We will also describe the analysis system and data basis on which monetary policy decisions are based. The handbook is intended as a living product, which will be updated as the strategy and modelling system evolve.
