The first day of January, 1959, saw the opening moves in the formation of the European Economic Community, the most spectacular experiment in regional economic integration to occur in recent history. If no hitches occur, within fifteen years West Germany, France, Italy, and the Benelux countries will have formed something between a customs union arid a full economic union, with internal free trade, a common external tariff, partial freedom of internal factor movement, partial co-ordination of economic and social policies, and a common framework of agricultural protection and control. There is a small and wildly fluctuating probability that this “common market” will become embedded in a larger European free trade area organized by Great Britain and including Denmark, Norway, Sweden, Switzerland, Austria, and possibly other small European nations.
