Abstract
The text describes the theoretical developments of the assignment rules regarding fiscal and monetary policies and the respective roles in macroeconomics stabilisation. Monetary policy emerged as the dominant policy, reducing the active macro-role of fiscal policy to taking care of debt sustainability. This consensus started to change, and a new view has appeared, giving a more active role to fiscal policy. The article concludes with a brief analysis of fiscal rules, followed by a discussion about the European Union fiscal framework, and its necessary revision.
