This text provides an account of the history, theory and practice of monetary integration in Europe. Starting with a brief history of European monetary integration up to the start of the EMS in 1978, the authors go on to examine in more detail the workings of the EMS, including an analysis of the speculative attacks in 1992-95. The next part of the book is a substantially rewritten account of the economics of monetary union with a fresh look at the costs and benefits, the changing relationships between economic and monetary integration and the global implications of EMU. The final part of the book critically examines the specific steps towards monetary union starting from the Delors Report to the Maastricht Treaty.
