Proposals for different types of elements of a fiscal union have flourished in recent years, both from academic and policy circles. Since a fiscal union could take a constellation of various different forms, this paper first provides an analytical framework pinpointing the five key elements of a fiscal union. It takes stock of the existing features of economic and monetary union (EMU) that embed some form of fiscal union, and then critically analyses the main arguments for and against further fiscal integration. Finally, It surveys the key proposals for a fiscal capacity and different types of Eurobonds.
