Let me express a different view. I think that the central government of any sovereign state ought to be striving all the time to determine the optimum overall level of public provision, the correct overall burden of taxation, the correct allocation of total expenditures between competing requirements and the just distribution of the tax burden. It must also determine the extent to which any gap between expenditure and taxation is financed by making a draft on the central bank and how much it is financed by borrowing and on what terms. The way in which governments decide all these (and some other) issues, and the quality of leadership which they can deploy, will, in interaction with the decisions of individuals, corporations and foreigners, determine such things as interest rates, the exchange rate, the inflation rate, the growth rate and the unemployment rate. It will also profoundly influence the distribution of income and wealth not only between individuals but between whole regions, assisting, one hopes, those adversely affected by structural change.

...

I recite all this to suggest, not that sovereignty should not be given up in the noble cause of European integration, but that if all these functions are renounced by individual governments they simply have to be taken on by some other authority. The incredible lacuna in the Maastricht programme is that, while it contains a blueprint for the establishment and modus operandi of an independent central bank, there is no blueprint whatever of the analogue, in Community terms, of a central government. Yet there would simply have to be a system of institutions which fulfils all those functions at a Community level which are at present exercised by the central governments of individual member countries.

What happens if a whole country - a potential `region' in a fully integrated community - suffers a structural setback? So long as it is a sovereign state, it can devalue its currency. It can then trade successfully at full employment provided its people accept the necessary cut in their real incomes. With an economic and monetary union, this recourse is obviously barred, and its prospect is grave indeed unless federal budgeting arrangements are made which fulfil a redistributive role. As was clearly recognised in the MacDougall Report which was published in 1977, there has to be a quid pro quo for giving up the devaluation option in the form of fiscal redistribution. Some writers (such as Samuel Brittan and Sir Douglas Hague) have seriously suggested that EMU, by abolishing the balance of payments problem in its present form, would indeed abolish the problem, where it exists, of persistent failure to compete successfully in world markets. But as Professor Martin Feldstein pointed out in a major article in the Economist (13 June), this argument is very dangerously mistaken. If a country or region has no power to devalue, and if it is not the beneficiary of a system of fiscal equalisation, then there is nothing to stop it suffering a process of cumulative and terminal decline leading, in the end, to emigration as the only alternative to poverty or starvation. I sympathise with the position of those (like Margaret Thatcher) who, faced with the loss of sovereignty, wish to get off the EMU train altogether. I also sympathise with those who seek integration under the jurisdiction of some kind of federal constitution with a federal budget very much larger than that of the Community budget. What I find totally baffling is the position of those who are aiming for economic and monetary union without the creation of new political institutions (apart from a new central bank), and who raise their hands in horror at the words `federal' or `federalism'. This is the position currently adopted by the Government and by most of those who take part in the public discussion.
