This paper intends to put into light the particularities of economic policies coordination in general and, more specifically, in the Economic and Monetary Union. The coordination of economic policies and especially of the common monetary policy with the national budgetary policies is determined by growing interdependences between member states and by the existence of some public goods within the Union and it aims at a quicker adjustment of shocks and at stabilizating the economy in the Eurozone. Realizing an efficient coordination of economic policies reprezents a necessary condition for achieving a stable and durable economic growth within the Union and it implies increasing the credibility of the authorities, transparency of the economic policies and, least but not last, increasing cooperation (dialogue) between authorities.
