In fact, there seems, instead, to be a risk of an economic government at the euro area level potentially being used as a scapegoat for unsuccessful policies at the national level, which would thus even undermine incentives for sound policy and effective policy coordination.
In the light of these considerations, it would seem that the main reason for the recent calls for an economic government is probably something else, namely a desire to establish political influence on monetary policy in the euro area and thereby to undermine the independence of the ECB.
