So far, I’ve been describing the economic logic for fiscal federalism. However I have not qualified it. It's all nice and easy to argue that we need to tax the richest and subsidise the poorest, but how do you do this? Which pockets should the EU reach into and what should it pay for?
In the next lines I propose the following Euro-level fiscal tools : (1)Taxes on mobile factors that cause negative externalities, (2)an Income tax, and the maintenance of a (3)common education policy as well as a (4)common defence policy, with a tendency for expansionary military R&D expenditure during recessions. Finally I also argue in favour of (5)the establishment of an European Monetary Fund (EMF) to switch from cooperation to coordination of euro-area fiscal policies. This would be the best tool to keep and improve the theoretically good monitoring devices created by the SGP, while replacing its very ineffective legalistic procedures, in order to improve fiscal stability across the board.
I believe these are the necessary tools for the EU to minimise its risks of suffering from asymmetric shocks, while endowing it with the policy tools to deal with them, should they arise, as they inevitably will. They may however not be sufficient...
